   OVERVIEW    Oncolytics Biotech Inc. is a Development Stage Company   

Since our inception in April of 1998, Oncolytics Biotech Inc. has been a development stage company and we have focused our research and development efforts on the development of REOLYSIN(R), our potential cancer therapeutic. We have not been profitable since our inception and expect to continue to incur substantial losses as we continue research and development efforts. We do not expect to generate significant revenues until, if and when, our cancer product becomes commercially viable.

General Risk Factors

Prospects for biotechnology companies in the research and development stage should generally be regarded as speculative. It is not possible to predict, based upon studies in animals, or early studies in humans, whether a new therapeutic will ultimately prove to be safe and effective in humans, or whether necessary and sufficient data can be developed through the clinical trial process to support a successful product application and approval.

If a product is approved for sale, product manufacturing at a commercial scale and significant sales to end users at a commercially reasonable price may not be successful. There can be no assurance that we will generate adequate funds to continue development, or will ever achieve significant revenues or profitable operations. Many factors (e.g. competition, patent protection, appropriate regulatory approvals) can influence the revenue and product profitability potential.

In developing a pharmaceutical product, we rely upon our employees, contractors, consultants and collaborators and other third party relationships, including the ability to obtain appropriate product liability insurance. There can be no assurance that these reliances and relationships will continue as required.

In addition to developmental and operational considerations, market prices for securities of biotechnology companies generally are volatile, and may or may not move in a manner consistent with the progress being made by Oncolytics.

REOLYSIN(R) Development Update for the First Quarter of 2008

We continue to develop our lead product REOLYSIN(R) as a potential cancer therapy. Our goal each year is to advance REOLYSIN(R) through the various steps and stages of development required for pharmaceutical products. In order to achieve this goal, we actively manage the development of our clinical trial program, our pre-clinical and collaborative programs, our manufacturing process and supply, and our intellectual property.

Clinical Trial Program

During the first quarter of 2008 our clinical trial program expanded to nine clinical trials of which seven are being conducted by us and two are being sponsored by the U.S. National Cancer Institute (“NCI”).

Clinical Trials – Actively Enrolling

During the first quarter of 2008, we continued to enroll patients in our Phase II combination REOLYSIN(R)/radiation and our three Phase I/II chemotherapeutic co-therapy clinical trials in the U.K. In the U.S., we continued to enroll patients in our Phase II sarcoma and in our Phase I/II recurrent malignant glioma clinical trials.

Clinical Trials – Expanded Enrollment

During the first quarter of 2008, we announced that we had met the initial criteria to proceed to full enrolment in our U.S. Phase II trial to evaluate the intravenous administration of REOLYSIN(R) in patients with various sarcomas that have metastasized to the lung.

According to the trial protocol, to proceed to full enrolment of 52 patients, we had to demonstrate that at least one patient in the first 38 patients treated experienced a complete or partial response, or stable disease for greater than six months. The third patient treated in the study was demonstrated to have stable disease by RECIST criteria for more than six months as measured by CT scan. A PET scan taken at the same time showed that any residual mass was metabolically inert.

This trial is a Phase II, open-label, single agent study whose primary objective is to measure tumour responses and duration of response, and to describe any evidence of antitumour activity of intravenous, multiple dose REOLYSIN(R) in patients with bone and soft tissue sarcomas metastatic to the lung. REOLYSIN(R) is delivered intravenously to patients at a dose of 3×1010 TCID50 for five consecutive days. Patients may receive additional five-day cycles of therapy every four weeks for a maximum of eight cycles. Up to 52 patients will be enrolled in the study.

Eligible patients must have a bone or soft tissue sarcoma metastatic to the lung deemed by their physician to be unresponsive to or untreatable by standard therapies. These include patients with osteosarcoma, Ewing sarcoma family tumours, malignant fibrous histiocytoma, synovial sarcoma, fibrosarcoma and leiomyosarcoma.

Clinical Trials – Recently Filed Application

In the first quarter of 2008, the NCI filed a protocol with the U.S. Food and Drug Administration for a Phase I/II clinical trial for patients with metastatic ovarian, peritoneal or fallopian tube cancers using concurrent systemic and intraperitoneal administration of REOLYSIN(R). The trial, which is being carried out at The Ohio State University Comprehensive Cancer Center, is expected to enroll up to 70 patients with metastatic ovarian, peritoneal or fallopian tube cancers. These cancer indications were selected after comprehensive preclinical studies carried out by the NCI indicated the reovirus can kill ovarian cancer cells.

Pre-Clinical Trial and Collaborative Program

In the first quarter of 2008, we reported that a research group led by Dr. Richard Vile of the Mayo Clinic College of Medicine in Rochester, Minnesota, published the results of its work testing the antitumor efficacy and safety of various combinations of reovirus and cyclophosphamide in vivo. The paper, entitled “Cyclophosphamide Facilitates Antitumor Efficacy against Subcutaneous Tumors following Intravenous Delivery of Reovirus” appeared online in the January 1, 2008 issue of Clinical Cancer Research.

The purpose of the research study was to investigate whether it was possible to use cyclophosphamide, an immune modulator, to enhance the delivery and replication of the reovirus when delivered intravenously. After testing various doses and dosing regimens of reovirus and cyclophosphamide in mice, a metronomic dosing regimen was developed that resulted in increased survival, high levels of reovirus recovered from regressing tumors, levels of neutralizing antibodies that were protective, and only very mild toxicities. The data support investigation in human clinical trials of the use of cyclophosphamide prior to systemic reovirus administration to modulate, but not ablate, the immune system.

We also reported that Dr. Kevin Harrington and his research group at The Institute of Cancer Research, London, U.K. published the results of their work testing combination treatment schedules of reovirus and radiation in human and murine tumour cells in vitro and in vivo. The paper, entitled “Enhanced In vitro and In vivo Cytotoxicity of Combined Reovirus and Radiotherapy” appeared online in the February 1, 2008 issue of Clinical Cancer Research.

The effect of different schedules of reovirus and radiotherapy on viral replication and cytotoxicity was tested in vitro and the combination was assessed in three tumour models in vivo. The results demonstrated that combining reovirus and radiotherapy significantly increased cancer cell killing both in vitro and in vivo, particularly in cell lines with moderate susceptibility to reovirus alone.

As well, in the first quarter of 2008, we reported that Dr. Kevin Harrington and his research group at The Institute of Cancer Research, London, U.K. published the results of their work characterizing immune system responses to administration of intravenous REOLYSIN(R) in a Phase I clinical trial. The paper, entitled “Characterization of the Adaptive and Innate Immune Response to Intravenous Oncolytic Reovirus (Dearing Type 3) during a Phase I Clinical Trial” appeared online in the March 6, 2008 issue of Gene Therapy.

The investigators conducted a detailed analysis of the immune effects of intravenous viral therapy by collecting and analyzing immune response to the presence of the virus. The results suggest that reovirus may stimulate the immune system to mount a dynamic immune response to the presence of virus, increasing the potential to significantly enhance the efficacy of oncolytic virotherapy. About a third of those patients also showed increases in NK (natural killer) cells following therapy. The data support the development of interventions aimed at blunting the patient’s immune response, although preclinical data also suggest that maintaining a baseline level is necessary to restrict systemic spread and toxicity of the virus.

Manufacturing and Process Development

In the first quarter of 2008, after completing the technology transfer of our 40-litre production process to our manufacturer in the U.S., we commenced production at the 40-litre scale under cGMP conditions for use in our clinical trials. Our process development activity continued to focus on scale up from 40-litre to 100-litre production runs.

Intellectual Property

During the first quarter of 2008, one U.S. and two Canadian patents were issued. At the end of the first quarter of 2008, we had been issued over 170 patents including 26 U.S. and eight Canadian patents as well as issuances in other jurisdictions. We also have over 180 patent applications filed in the U.S., Canada and other jurisdictions.

Financial Impact

We estimated at the beginning of 2008 that our average monthly cash usage would be approximately $1,660,000 for 2008. Our cash usage for the first quarter of 2008 was $2,991,234 from operating activities and $259,969 for the purchases of intellectual property and capital assets which is lower than our expected monthly average but is in line with our expectations for 2008. Our net loss for the first quarter of 2007 was $3,324,241.

Cash Resources

We exited the first quarter of 2008 with cash resources totaling $21,962,626 (see “Liquidity and Capital Resources”).

Expected REOLYSIN(R) Development for the Remainder of 2008

We plan to continue to enroll patients in our clinical trials throughout 2008 and still expect to complete enrollment in our co-therapy trials in the U.K. and our sarcoma study in the U.S. We believe that the results from these trials will allow us to broaden our Phase II clinical trial program and choose a pivotal trial path. As well, we believe that the NCI will commence enrollment in its two sponsored clinical trials.

We expect to produce REOLYSIN(R) for our clinical trial program throughout 2008. We believe we will complete our 100-litre scale up studies and will continue our examination of a lyophilization (freeze drying) process for REOLYSIN(R).

We continue to estimate, based on our expected activity for 2008 that our average monthly cash usage will be $1,660,000 per month (see “Liquidity and Capital Resources”).

   Recent 2008 Progress    Clinical Trials – Positive Interim Results   

In April, we announced positive interim results and completion of the dose escalation portion of our U.K. combination REOLYSIN(R) and carboplatin/paclitaxel trial. Four of the first eight patients treated in the study to date have a diagnosis of carcinoma of the head and neck. All three head and neck patients evaluated to date have had excellent clinical and radiological responses without appreciable toxicity. Preliminary assessment after recruitment of the first two cohorts has suggested that patients with head and neck carcinomas represent a group of patients for whom the combination of carboplatin/paclitaxel and REOLYSIN(R) may prove effective.

In the first cohort, the patient with head and neck cancer received 8 cycles of treatment (the maximum allowed) and achieved a clinical complete response. In the second cohort, the two patients with head and neck cancers with widespread disseminated disease have each received seven cycles of treatment to date and both have achieved significant partial responses. Two of the three patients, including the patient with the clinical complete response, had previously received cisplatin/5-FU treatment and all three had previously received radiotherapy.

This clinical trial has two components. The first is an open-label, dose-escalating, non-randomized study of REOLYSIN(R) given intravenously with paclitaxel and carboplatin every three weeks. Standard dosages of paclitaxel and carboplatin were delivered to patients with escalating dosages of REOLYSIN(R) intravenously. The second component of the trial includes the enrolment of a further 12 patients at the maximum dosage of REOLYSIN(R) in combination with a standard dosage of paclitaxel and carboplatin.

Eligible patients include those who have been diagnosed with advanced or metastatic solid tumours such as head and neck, melanoma, lung and ovarian cancers that are refractory (have not responded) to standard therapy or for which no curative standard therapy exists. The primary objective of the trial is to determine the Maximum Tolerated Dose (MTD), Dose-Limiting Toxicity (DLT), recommended dose and dosing schedule and safety profile of REOLYSIN(R) when administered in combination with paclitaxel and carboplatin. Secondary objectives include the evaluation of immune response to the drug combination, the body’s response to the drug combination compared to chemotherapy alone and any evidence of anti-tumour activity.

Collaborations – Results

On April 15, 2008, we announced that a poster presentation by Dr. Anders Kolb of the Nemours Center for Childhood Cancer Research entitled “Radiation in Combination with Reolysin for Pediatric Sarcomas” was presented at the American Association for Cancer Research (“AACR”) Annual Meeting. The poster covers preclinical work using reovirus in combination with radiation in mice implanted with pediatric rhabdomyosarcoma and Ewing’s sarcoma tumours. The results demonstrated that the combination of reovirus and radiation significantly enhanced efficacy compared to either treatment alone in terms of tumour regression and event-free survival.

On April 15, 2008, we announced that an oral presentation by Dr. Chandini Thirukkumaran of the Tom Baker Cancer Centre, Calgary, entitled “Targeting Multiple Myeloma with Oncolytic Viral Therapy” was presented at the AACR Annual Meeting. The presentation covered preclinical work using reovirus as a purging agent during autologous (harvested from the patient themselves) hematopoietic stem cell transplants for multiple myeloma. The results demonstrated that up to 70% of multiple myeloma cell lines tested showed reovirus sensitivity and reovirus induced cancer cell death mediated through apoptosis.

On April 16, 2008, we announced that Prof. Alan Melcher and his research group at St. James’s University Hospital in Leeds, U.K. published the results of their work in the April 10 online issue of Gene Therapy. The paper is entitled “Inflammatory Tumour Cell Killing by Oncolytic Reovirus for the Treatment of Melanoma.” The investigators showed that reovirus effectively kills and replicates in both human melanoma cell lines and freshly resected tumour. They demonstrated that reovirus melanoma killing is more potent than, and distinct from, chemotherapy or radiotherapy-induced cell death. They concluded that reovirus is suitable for clinical testing in melanoma.

RESULTS OF OPERATIONS

Net loss for the three month period ending March 31, 2008 was $3,324,241 compared to $4,113,231 for the three month period ending March 31, 2007.

   Research and Development Expenses (“R&D”)                                                           2008       2007                                                            $          $   ————————————————————————-   Manufacturing and related process    development expenses                                 503,094  1,838,193   Clinical trial expenses                             1,042,791    721,617   Pre-clinical trial expenses and collaborations              –    106,281   Other R&D expenses                                    579,926    552,146   ————————————————————————-   Research and development expenses                   2,125,811  3,218,237   ————————————————————————-   ————————————————————————-   

For the first quarter of 2008, R&D decreased to $2,125,811 compared to $3,218,237 for the first quarter of 2007. The decrease in R&D was due to the following:

   Manufacturing & Related Process Development (“M&P”)                                                           2008       2007                                                            $          $   ————————————————————————-   Product manufacturing expenses                        467,328  1,748,417   Process development expenses                           35,766     89,776   ————————————————————————-   Manufacturing and related process development    expenses                                             503,094  1,838,193   ————————————————————————-   ————————————————————————-   

Our M&P expenses for the first quarter of 2008 decreased to $503,094 compared to $1,838,193 for the first quarter of 2007.

In the first quarter of 2008, our production activity decreased compared to the first quarter of 2007. During the first quarter of 2008, we entered into a contract to manufacture REOLYSIN(R) at the 40-litre scale. We commenced production under this contract towards the end of the first quarter of 2008. In the first quarter of 2007, along with a number of manufacturing runs at the 20-litre scale, we also incurred vial filling activity for the production runs that were completed at the end of 2006.

Our process development expenses for the first quarter of 2008 were $35,766 compared to $89,776 for the first quarter of 2007. In the first quarter of 2008, our process development focus continues to be on the scale up to 100-litre production runs. In the first quarter of 2007, our process development focus was on our earlier 40-litre scale up studies.

We still expect that our M&P expenses for 2008 will increase compared to 2007. We have initiated our 40-litre production runs which will continue throughout 2008. As well, we still expect to finalize our 100-litre scale up studies and continue the examination of a lyophilization process for REOLYSIN(R) in 2008. Once our 100-litre process development studies are complete, we expect to transfer our 100-litre manufacturing process to our cGMP manufacturers.

   Clinical Trial Program                                                           2008       2007                                                            $          $   ————————————————————————-   Direct clinical trial expenses                        994,646    683,107   Other clinical trial expenses                          48,145     38,510   ————————————————————————-   Clinical trial expenses                             1,042,791    721,617   ————————————————————————-   ————————————————————————-   

During the first quarter of 2008, our direct clinical trial expenses increased to $994,646 compared to $683,107 for the first quarter of 2007. In the first quarter of 2008, we incurred direct patient costs in our six enrolling clinical trials compared to only three actively enrolling clinical trials in the first quarter of 2007.

We still expect our clinical trial expenses to increase in 2008 compared to 2007. The increase in these expenses is expected to arise from continued enrollment and continued re-treatments in our existing clinical trials.

   Pre-Clinical Trial Expenses and Research Collaborations                                                           2008       2007                                                            $          $   ————————————————————————-   Research collaboration expenses                             –    106,281   Pre-clinical trial expenses                                 –          –   ————————————————————————-   Pre-clinical trial expenses and research    collaborations                                             –    106,281   ————————————————————————-   ————————————————————————-   

During the first quarter of 2008, our research collaboration activity focused on renewing specific collaborations, but no costs were incurred compared to $106,281 for the first quarter of 2007. Our research collaboration activity continues to focus on the interaction of the immune system and the reovirus and the use of the reovirus as a co-therapy with existing chemotherapeutics and radiation.

We still expect that our pre-clinical trial expenses and research collaborations in 2008 will remain consistent with 2007.

   Other Research and Development Expenses                                                           2008       2007                                                            $          $   ————————————————————————-   R&D consulting fees                                    27,408     91,776   R&D salaries and benefits                             478,118    372,389   Other R&D expenses                                     74,400     87,981   ————————————————————————-   Other research and development expenses               579,926    552,146   ————————————————————————-   ————————————————————————-   

During the first quarter of 2008, our R&D consulting fees were $27,408 compared to $91,776 for the first quarter of 2007. In the first quarter of 2007, we incurred consulting activity associated with our co-therapy clinical trial applications that was not incurred in the first quarter of 2008.

Our R&D salaries and benefits costs were $478,118 for the first quarter of 2008 compared to $372,389 for the first quarter of 2007. The increase is a result of increases in salary levels for 2008 compared to 2007.

We still expect that our Other R&D expenses will remain consistent with 2007.

   Operating Expenses                                                           2008       2007                                                            $          $   ————————————————————————-   Public company related expenses                       759,970    581,876   Office expenses                                       324,284    324,839   ————————————————————————-   Operating expenses                                  1,084,254    906,715   ————————————————————————-   ————————————————————————-   

During the first quarter of 2008, our public company related expenses were $759,970 compared to $581,876 for the first quarter of 2007. In the first quarter of 2008, we incurred an increase in professional fees associated with the expansion of our corporate structure, an increase in our investor relations activity, and an increase in compensation costs paid to our board of directors compared to the first quarter of 2007.

During the first quarter of 2008, our office expenses were $324,284 compared to $324,839 for the first quarter of 2007. Our office expense activity has remained consistent in the first quarter of 2008 compared to the first quarter of 2007.

Commitments

As at March 31, 2008, we are committed to payments totaling $2,497,000 during the remainder of 2008 for activities related to clinical trial activity, manufacturing and collaborations. All of these committed payments are considered to be part of our normal course of business.

See note 2 to the       audited financial statements for 2007.   (2) Included in total cash are cash and cash equivalents plus short-term       investments.   (3) Included in net loss and loss per common share between March 2008 and       April 2006 are quarterly stock based compensation expenses of       $19,593, $396,278, $38,909, $82,573, $21,396, $109,670, $34,671, and       $222,376, respectively.   (4) We issued 4,600,000 units for net cash proceeds of $12,063,394 during       2007 with each unit consisting of one common share and one half of       one common share purchase warrant. (2006 – 284,000 common shares for       cash proceeds of $241,400)   (5) The long-term debt recorded represents repayable loans from the       Alberta Heritage Foundation. On January 1, 2007, in conjunction with       the adoption of the CICA Handbook section 3855 “Financial       Instruments”, this loan was recorded at fair value (see note 3 of the       December 31, 2007 audited financial statements).   (6) We have not declared or paid any dividends since incorporation.     LIQUIDITY AND CAPITAL RESOURCES    Liquidity   

As at March 31, 2008, we had cash and cash equivalents (including short-term investments) and working capital positions of $21,962,626 and $19,457,103, respectively compared to $25,213,829 and $22,732,987, respectively for December 31, 2007. The decrease in the first quarter of 2008 reflects the cash usage from our operating activities and purchase of intellectual property of $2,991,234 and $257,304, respectively.

We desire to maintain adequate cash and short-term investment reserves to support our planned activities which include our clinical trial program, product manufacturing, administrative costs, and our intellectual property expansion and protection. In 2008, we expect to continue to enroll patients in our various clinical trials and we also expect to continue with our collaborative studies pursuing support for our clinical trial program. We will therefore need to ensure that we have enough REOLYSIN(R) to supply our clinical trial and collaborative programs. We still expect our average monthly cash usage to be $1,660,000 in 2008 and we believe our existing capital resources are adequate to fund our current plans for research and development activities well into 2009. Factors that will affect our anticipated monthly burn rate include, but are not limited to, the number of manufacturing runs required to supply our clinical trial program and the cost of each run, the number of clinical trials ultimately approved, the timing of patient enrollment in the approved clinical trials, the actual costs incurred to support each clinical trial, the number of treatments each patient will receive, the timing of the NCI’s R&D activity, and the level of pre-clinical activity undertaken.

In the event that we choose to seek additional capital, we will look to fund additional capital requirements primarily through the issue of additional equity. We recognize the challenges and uncertainty inherent in the capital markets and the potential difficulties we might face in raising additional capital. Market prices and market demand for securities in biotechnology companies are volatile and there are no assurances that we will have the ability to raise funds when required.

Capital Expenditures

We spent $257,304 on intellectual property in the first quarter of 2008 compared to $218,177 in the first quarter of 2007. The change in intellectual property expenditures reflects the timing of filing costs associated with our expanded patent base. As well, we have benefited from fluctuations in the Canadian dollar as our patent costs are typically incurred in U.S. currency. At the end of the first quarter of 2008, we had been issued over 170 patents including 26 U.S. and eight Canadian patents as well as issuances in other jurisdictions. We also have over 180 patent applications filed in the U.S., Canada and other jurisdictions.

Investing Activities

Under our Investment Policy, we are permitted to invest in short-term instruments with a rating no less than R-1 (DBRS) with terms less than two years. We have $14,635,920 invested under this policy and we are currently earning interest at an effective rate of 2.74% (2007 – 4.08%).

   CHANGES IN ACCOUNTING POLICIES INCLUDING INITIAL ADOPTION    Capital Disclosures   

On January 1, 2008, the Company adopted the new recommendations of the Canadian Institute of Chartered Accountants (“CICA”) for disclosure of the Company’s objectives, policies and processes for managing capital (CICA Handbook Section 1535), as discussed further in Note 5 of our interim consolidated financial statements.

Financial Instruments – Disclosures

On January 1, 2008, the Company adopted the new recommendations of the CICA for disclosures about financial instruments, including disclosures about fair value and the credit, liquidity and market risks associated with financial instruments (CICA Handbook Section 3862), as discussed further in Notes 6 and 7 of our interim consolidated financial statements.

Financial Instruments – Presentation

On January 1, 2008, the Company adopted the new recommendations of the CICA for presentation of financial instruments (CICA Handbook Section 3863). Adoption of this standard had no impact on the Company’s financial instrument related presentation disclosures.

OTHER MD&A REQUIREMENTS

We have 41,180,748 common shares outstanding at April 30, 2008. If all of our warrants (4,220,000) and options (3,870,493) were exercised we would have 49,271,241 common shares outstanding.

Pursuant       to the transitional provisions of Section 3855, the Company       classified its short-term investments as held-to-maturity fixed       income securities and recorded its Alberta Heritage Foundation       interest free loan at fair value. As a result, there were no       adjustments made to short-term investments or other comprehensive       income and there was a decrease in the Alberta Heritage Foundation       loan of $150,000 with a corresponding decrease of $150,000 in the       Company’s deficit.     5.

CAPITAL DISCLOSURES    The Company’s objective when managing capital is to maintain adequate   cash resources to support planned activities which include the clinical   trial program, product manufacturing, administrative costs and   intellectual property expansion and protection. The Company includes   shareholders’ equity, cash and short-term investments in the definition   of capital. The Company does not have any debt other than trade accounts   payable and has potential contingent obligations relating to the   completion of its research and development of REOLYSIN(R).    In managing capital, the Company estimates its future cash requirements   by preparing a budget and a multiyear plan annually for review and   approval by the Company’s board of directors (the “Board”). The budget   establishes the approved activities for the upcoming year and estimates   the costs associated with these activities. The multiyear plan estimates   future activity along with the potential cash requirements and is based   on the Company’s assessment of its current clinical trial progress along   with the expected results from the coming year’s activity. Budget to   actual variances are prepared monthly and reviewed by the Company’s   management and are presented quarterly to the Board.    Historically, funding for the Company’s plan is primarily managed through   the issuance of additional common shares and common share purchase   warrants that upon exercise are converted to common shares. Management   regularly monitors the capital markets attempting to balance the timing   of issuing additional equity with the Company’s progress through its   clinical trial program, general market conditions, and the availability   of capital. There are no assurances that funds will be made available to   the Company when required.    The Company is not subject to externally imposed capital requirements.    7.  SHORT-TERM INVESTMENTS    Short-term investments, consisting of bankers’ acceptances, are liquid   investments that are readily convertible to known amounts of cash and are   subject to an insignificant risk of changes in value. The objectives for   holding short-term investments are to invest the Company’s excess cash   resources in investment vehicles that provide a better rate of return   compared to the Company’s interest bearing bank account with limited risk   to the principal invested. The Company also intends to match the   maturities of these short-term investments with the cash requirements of   the Company’s activities. The Company does not hold any asset backed   commercial paper.                                                                   Effective                       Original    Accrued    Carrying      Fair   Interest                         Cost      Interest     Value       Value    Rate                           $           $          $           $   ————————————————————————-   March 31, 2008   Short-term    investments       14,576,744     59,176  14,635,920  14,539,205   2.74%   ————————————————————————-   ————————————————————————-    ————————————————————————-   December 31, 2007   Short-term    investments       18,230,340    268,393  18,498,733  18,499,173   4.26%   ————————————————————————-   ————————————————————————-    Fair value is determined by using published market prices provided by the   Company’s investment advisor.    8.  FINANCIAL INSTRUMENTS    Financial instruments of the Company consist of cash and cash   equivalents, short-term investments, accounts receivable, and accounts   payable. As at March 31, 2008, there are no significant differences   between the carrying values of these amounts and their estimated market   values.    Credit risk    Credit risk is the risk of financial loss to the Company if a   counterparty to a financial instrument fails to meet its contractual   obligations. The Company is exposed to credit risk on its cash and cash   equivalents and short-term investments in the event of non-performance by   counterparties, but does not anticipate such non-performance. The maximum   exposure to credit risk of the Company at the end of the period is the   carrying value of its cash and cash equivalents and short-term   investments.    The Company mitigates its exposure to credit risk by maintaining its   primary operating and investment bank accounts with Schedule I banks in   Canada. For its foreign domiciled bank accounts, the Company uses   referrals or recommendations from its Canadian banks to open foreign bank   accounts and these accounts are used solely for the purpose of settling   accounts payable or payroll.    The Company also mitigates its exposure to credit risk by restricting its   portfolio to investment grade securities with short term maturities and   by monitoring the credit risk and credit standing of counterparties.    Interest rate risk    Interest rate risk is the risk that future cash flows of a financial   instrument will fluctuate because of changes in market interest rates.   The Company is exposed to interest rate risk through its cash and cash   equivalents and its portfolio of short-term investments. The Company   mitigates this risk through its investment policy that only allows   investment of its excess cash resources in investment grade vehicles   while matching maturities with the Company’s operational requirements.    Fluctuations in market rates of interest do not have a significant impact   on the Company’s results of operations due to the short term to maturity   of the investments held.    Currency risk    Currency risk is the risk that future cash flows of a financial   instrument will fluctuate because of changes in foreign exchange rates.   The Company is exposed to currency risk from the purchase of goods and   services primarily in the U.S. and the U.K. The Company mitigates its   foreign exchange risk through the purchase of foreign currencies in   sufficient amounts to settle its foreign accounts payable.    Balances in foreign currencies at March 31, 2008 are as follows:                                                          U.S.      British                                                       dollars      pounds                                                          $      (pnds stlg)   ————————————————————————-   Cash and cash equivalents                            441,078     181,214   Accounts payable                                    (440,988)    (35,985)   ————————————————————————-                                                             90     145,229   ————————————————————————-   ————————————————————————-    Liquidity risk    Liquidity risk is the risk that the Company will encounter difficulty in   meeting obligations associated with financial liabilities. The Company   manages liquidity risk through the management of its capital structure as   outlined in note 6 to the unaudited financial statements.    Accounts payable are all due within the current operating period.    About Oncolytics Biotech Inc.
