    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 2007

We continue to develop our lead product REOLYSIN(R) as a possible cancer
therapy. Our goal each year is to advance REOLYSIN(R) through the various
steps and stages of development required for potential 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

We currently have six clinical trials ongoing of which three are actively
enrolling patients and three have been recently approved.

Clinical Trials – Actively Enrolling

During the first quarter of 2007, we continued to enroll patients in our
phase II and Phase Ib combination REOLYSIN(R)/radiation clinical trials in the
U.K. and in our Phase I/II recurrent malignant glioma clinical trial in the
U.S.

Clinical Trials – Recently Approved to Commence

Along with our U.K. REOLYSIN(R) in combination with paclitaxel and
carboplatin clinical trial, we received approval to commence two additional
co-therapy clinical trials in the U.K.

U.K. REOLYSIN(R) in Combination with Docetaxel

In the first quarter of 2007, we announced we had received a letter of
approval from the U.K. Medicines and Healthcare products Regulatory Agency
(“MHRA”) for our Clinical Trial Application (“CTA”) to begin a clinical trial
using intravenous administration of REOLYSIN(R) in combination with docetaxel
(Taxotere(R)) in patients with advanced cancers including bladder, prostate,
lung and upper gastro-intestinal. The principal investigator is Professor
Hardev Pandha of The Royal Surrey Hospital, U.K. Docetaxel is used in patients
with lung, breast and prostate cancers, and is also used widely in the
treatment of many other types of cancers.

The trial has two components. The first is an open-label, dose-escalating,
non-randomized study of REOLYSIN(R) given intravenously with docetaxel every
three weeks. A standard dosage of docetaxel will be delivered with escalating
dosages of REOLYSIN(R) intravenously. A maximum of three cohorts will be
enrolled in the REOLYSIN(R) dose escalation portion. The second component of
the trial will immediately follow and will include the enrolment of a further
12 patients at the maximum dosage of REOLYSIN(R) in combination with a
standard dosage of docetaxel.

Eligible patients include those who have been diagnosed with advanced or
metastatic solid tumours such as bladder, lung, prostate or upper
gastro-intestinal cancers that are refractory 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 docetaxel. 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.

U.K. REOLYSIN(R) in Combination with Gemcitabine

During the first quarter of 2007, we announced we had received a letter of
approval from the MHRA to begin a clinical trial using intravenous
administration of REOLYSIN(R) in combination with gemcitabine (Gemzar(R)) in
patients with advanced cancers including pancreatic, lung and ovarian. The
principal investigators are Dr. Johann de Bono of The Royal Marsden NHS
Foundation Trust and The Institute of Cancer Research, London and Professor
Jeff Evans of the University of Glasgow and the Beatson Oncology Centre in
Glasgow, Scotland. Gemcitabine is used in patients with lung, pancreatic and
ovarian cancers and is also used widely in the treatment of many other types
of cancers.

This trial has two components. The first is an open-label,
dose-escalating, non-randomized study of REOLYSIN(R) given intravenously with
gemcitabine every three weeks. A standard dosage of gemcitabine will be
delivered with escalating dosages of REOLYSIN(R) intravenously. A maximum of
three cohorts will be enrolled in the REOLYSIN(R) dose escalation portion. The
second component of the trial will immediately follow and will include the
enrolment of a further 12 patients at the maximum dosage of REOLYSIN(R) in
combination with a standard dosage of gemcitabine.

Eligible patients include those who have been diagnosed with advanced or
metastatic solid tumours including pancreatic, lung and ovarian cancers that
are refractory to standard therapy or for which no curative standard therapy
exists. The primary objective of the trial is to determine the MTD, DLT,
recommended dose and dosing schedule and safety profile of REOLYSIN(R) when
administered in combination with gemcitabine. 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.

Pre-Clinical Trial and Collaborative Program

In the first quarter of 2007, an oral presentation entitled “Reovirus as a
Potentially Immunogenic as well as Cytotoxic Therapy for Metastatic Colorectal
Cancer” was given by one of our collaborators, Dr. Sheila Fraser of St.
James’s University Hospital in Leeds, U.K. The investigators tested reovirus
in vitro against recently resected colorectal cancer liver metastases. The
results showed that a significant proportion of tumour cell cultures showed
susceptibility to death following reovirus infection, and also demonstrated
effective replication of reovirus within these cells. In addition, dendritic
cells that prime the immune system to fight cancer cells were activated by
exposure to the reovirus. The investigators concluded that the data supports
the development of reovirus as a novel therapy for colorectal cancer, with the
potential to direct the immune system to target cancer cells.

During the first quarter of 2007, an abstract entitled “In Vivo Synergy
between Oncolytic Reovirus and Gemcitabine in Ras-Mutated Human HCT116
Xenografts” was made available on the American Association for Cancer Research
(AACR) website at www.aacr.org. The abstract covered preclinical work using
reovirus in combination with gemcitabine and showed the combination of
reovirus and gemcitabine was more effective than gemcitabine or reovirus alone
at killing human colon cancer cells in a mouse model.

In March 2007, Professor Hardev Pandha of The Royal Surrey Hospital, U.K.
presented a poster entitled “Synergistic Antitumour Activity of Oncolytic
Reovirus and Cisplatin in Malignant Melanoma” at the 4th International
Conference on Oncolytic Viruses as Cancer Therapeutics in Carefree, Arizona.
The results of the preclinical study showed that the combination of reovirus
and cisplatin was significantly more effective than cisplatin or reovirus
alone at killing melanoma cancer cells in a mouse model. The investigators
concluded that the addition of chemotherapeutic agents can enhance the
efficacy of reovirus therapy.

Finally in March 2007, Dr. Richard Vile of the Mayo College of Medicine,
Rochester, Minnesota delivered an oral presentation at the 4th International
Conference on Oncolytic Viruses as Cancer Therapeutics in Carefree, Arizona
that covered a study of systemic administration of reovirus in combination
with cyclophosphamide, an immune modulator. The work demonstrated that
systemic administration of reovirus in combination with cyclophosphamide
enhanced tumour regression in a melanoma animal model without increasing
toxicity. In addition, the investigators were able to demonstrate that the
addition of cyclophosphamide significantly increased the amount of reovirus
replicating within the tumour. The investigators concluded that the addition
of cyclophosphamide may lead to improved efficacy of REOLYSIN(R) treatment.

Manufacturing and Process Development

We continued to have REOLYSIN(R) manufactured in order to supply our
current and future clinical trial program. In the first quarter of 2007, we
contracted for additional cGMP (“current good manufacturing practices”)
production runs. As well, we continued process development activity focused on
the potential scale up of our manufacturing process.

Intellectual Property

In the first quarter of 2007, two U.S. patents were issued. At the end of
the first quarter of 2007, we had been issued a total of 19 U.S., five
Canadian and three European patents. We also have other patent applications
filed in the U.S., Europe and Canada and other jurisdictions.

Financing Activity

During the first quarter of 2007, we issued 4,600,000 units at a price of
$3.00 per unit for net proceeds of $12,068,172. Each unit consisted of one
common share and one-half of one common share purchase warrant. Each whole
common share purchase warrant shall entitle the holder thereof to acquire one
common share upon payment of $3.50 expiring on February 22, 2010. The net
proceeds from this offering will be used for our clinical trial program,
manufacturing activities in support of the clinical trial program and for
general corporate purposes.

Financial Impact

We estimated at the beginning of 2007 that our monthly cash usage would be
approximately $1,400,000 for 2007. Our cash usage for the first quarter of
2007 was $3,747,709 from operating activities and $252,925 for the purchases
of intellectual property and capital assets which is in line with our
estimate. Our net loss for the first quarter of 2007 was $4,113,231.

Cash Resources

We exited the first quarter of 2007 with cash resources totaling
$35,681,286 (see “Liquidity and Capital Resources”).

Expected REOLYSIN(R) Development for the Remainder of 2007

We believe that we will continue to expand our clinical trials to include
studies investigating REOLYSIN(R) as a monotherapy. As well, we expect to
commence enrollment in our co-therapy chemotherapy clinical trials in 2007 and
to continue to enroll patients in our other trials. We believe we will
complete enrollment in our U.K. Phase Ia/Ib and Phase II combination REOLYSIN
(R) /radiation clinical trials by the end of 2007 and complete enrollment in
our chemotherapy co-therapy studies in 2008. We expect to produce REOLYSIN(R)
in 2007 to supply our clinical trial program. We also plan to complete our
scale up studies in an effort to continue to improve our manufacturing
process.

Based on our expected activity in 2007, we continue to estimate our
monthly cash usage to be $1,400,000 per month (see “Liquidity and Capital
Resources”).

    Recent 2007 Progress

    U.S. Phase II Sarcoma Clinical Trial

On April 11, 2007, we announced that subsequent to the regulatory review
period for this submission, we are proceeding with a Phase II trial to
evaluate the intravenous administration of REOLYSIN(R) in patients with
various sarcomas that have metastasized to the lung. The Principal
Investigators are Dr. Glenn S. Kroog of the Montefiore Medical Center/Albert
Einstein College of Medicine in the Bronx, New York, Dr. Laurence H. Baker of
the University of Michigan Comprehensive Cancer Center in Ann Arbor, and Dr.
Monica Mita of the Cancer Therapy and Research Center, Institute for Drug
Development in San Antonio, Texas.

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) will be given intravenously to patients at a dose of 3×10
(10) TCID (50) 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.

RESULTS OF OPERATIONS

Net loss for the three month period ending March 31, 2007 was $4,113,231
compared to $2,994,536 for the three month period ending March 31, 2006.

For the first quarter of 2007, R&D increased to $3,218,237 compared to
$1,916,322 for the first quarter of 2006. The increase in R&D was due to the
following:

    Manufacturing & Related Process Development ("M&P")

    -------------------------------------------------------------------------
    -------------------------------------------------------------------------

Our M&P expenses for the first quarter of 2007 increased to $1,838,193
compared to $843,141 for the first quarter of 2006.

In the first quarter of 2007, our production and vial filling activity
increased compared to the first quarter of 2006. In the first quarter of 2007,
we commenced additional production runs to manufacture REOLYSIN(R). As well,
we incurred costs associated with the vialling of our production runs that
were completed at the end of 2006. In the first quarter of 2006, we were
completing the production runs that had started at the end of 2005.

Our process development expenses for the first quarter of 2007 were
$89,776 compared to $199,718 for the first quarter of 2006. In the first
quarter of 2007, our main process development focus was on our scale up
studies. In the first quarter of 2006, our process development activity
included scale up studies and the validation of the fill process used in our
manufacturing process.

We still expect that our overall manufacturing and related process
development expenses for 2007 will decrease compared to 2006. We expect to
complete our planned 2007 production runs in the third quarter of 2007. As
well, we expect to continue our process development activity that is examining
the potential scale up of our manufacturing process.

We are also examining ways to reduce our economic dependence resulting
from having only a single cGMP manufacturer. This might include building up a
level of inventory, increasing the scale of each production run, engaging
another cGMP manufacturer or manufacturing REOLYSIN(R) ourselves. Depending on
how we mitigate our risk of economic dependence our expectation of our 2007
M&P expenses may change.

    -------------------------------------------------------------------------

During the first quarter of 2007, our direct clinical trial expenses
increased to $683,107 compared to $499,633 for the first quarter of 2006. In
the first quarter of 2007, we incurred direct patient costs in our three
ongoing clinical trials along with start up costs associated with our three
U.K. co-therapy clinical trials that were approved to commence at the end of
2006 and at the beginning of 2007. In the first quarter of 2006, we incurred
direct patient costs in our three ongoing clinical trials.

We still expect our clinical trial expenses in 2007 will increase compared
to 2006 as we expect to commence enrollment in our U.K. co-therapy trials in
2007. As well, we expect to continue to expand our clinical trial program to
include additional Phase II trials.

    -------------------------------------------------------------------------

During the first quarter of 2007, our research collaboration expenses were
$106,281 compared to $155,086 for the first quarter of 2006. 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. As well, we will also examine the
use of new RAS active viruses as potential therapeutics and investigate new
uses of the reovirus in therapy.

For the remainder of 2007, we still expect that pre-clinical trial
expenses and research collaborations will decline compared to 2006. We expect
to continue with our various collaborations in order to provide support for
our expanding clinical trial program. As well, we may expand our collaborative
activities to include other viruses.

During the first quarter of 2007, our R&D consulting fees were $91,776
compared to $32,955 for the first quarter of 2006. In the first quarter of
2007, we incurred consulting activity associated with our ongoing clinical
trials and assistance with our clinical trial applications. In the first
quarter of 2006, our consulting activity related to our ongoing clinical
trials.

Our R&D salaries and benefits costs were $372,389 in the first quarter of
2007 compared to $321,125 in the first quarter of 2006. The increase is a
result of increases in salary and staff levels along with the hiring of our
Vice President of Intellectual Property in 2007.

We now expect that our other research and development expenses for the
remainder of 2007 will increase compared to 2006. We expect that salaries and
benefits will increase to reflect increased compensation levels and the salary
and benefit costs for our Vice President of Intellectual Property. Our R&D
consulting fees are expected to remain consistent with 2006. However, we may
choose to engage additional consultants to assist us in the development of
protocols and regulatory filings for our additional combination therapy and
phase II clinical trial studies, possibly causing our R&D consulting expenses
to increase.

    -------------------------------------------------------------------------

During the first quarter of 2007, our public company related expenses were
$581,876 compared to $834,720 for the first quarter of 2006. In the first
quarter of 2006, we incurred financial advisory costs that were not incurred
in the first quarter of 2007.

During the first quarter of 2007, our office expenses were $324,839
compared to $283,216 for the first quarter of 2006. Our office expense
activity has remained consistent in the first quarter of 2007 compared to the
first quarter of 2006 with increases mainly due to increased compensation
levels and a general increase in office costs.

Commitments

As at March 31, 2007, we are committed to payments totaling $1,623,000
during the remainder of 2007 for activities related to clinical trial activity
and collaborations. All of these committed payments are considered to be part
of our normal course of business.

    (1) Subsequent to the acquisition of Oncolytics Biotech Inc. by SYNSORB
        in April 1999, we applied push down accounting. See note 2 to the
        audited financial statements for 2006.
    (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 2007 and
        April 2004 are quarterly stock based compensation expenses of
        $64,167, $109,670, $34,671, $222,376, $36,833, $38,152, $4,173, and
        $8,404, respectively.
    (4) We issued 4,600,000 common shares for net cash proceeds of $12,068
        during 2007 (2006 - 284,000 common shares for cash proceeds of
        $241,400; 2005 - 4,321,252 common shares for cash proceeds of
        $18,789,596).
    (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 1 of the
        March 31, 2007 interim financial statements).
    (6) We have not declared or paid any dividends since incorporation.

    LIQUIDITY AND CAPITAL RESOURCES

    Liquidity

As at March 31, 2007, we had cash and cash equivalents (including
short-term investments) and working capital positions of $35,681,286 and
$33,664,830, respectively compared to $27,613,748 and $25,719,870,
respectively for December 31, 2006. The increase in 2007 reflects the cash
inflow from financing activities of $12,068,172 offset by cash usage from
operating activities and purchases of intellectual property of $3,747,709 and
$218,177, 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. For the remainder of 2007, we are expecting to
commence patient enrollment in our co-therapy trials and continue to enroll
patients in our existing trials throughout 2007. We also expect to continue to
expand our clinical trial program. As well we expect to continue with our
collaborative studies pursuing support for our future clinical trial program.
We will therefore need to ensure that we have enough REOLYSIN(R) to supply our
clinical trial and collaborative programs. We continue to expect our cash
usage in 2007 to be $1,400,000 per month 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 $218,177 on intellectual property in the first quarter of 2007
compared to $230,948 in the first quarter of 2006. The change in intellectual
property expenditures reflects the timing of filing costs associated with our
expanded patent base. In the first quarter of 2007, two U.S. patents were
issued bringing our total patents issued to 19 in the U.S., five in Canada and
three in Europe.

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 $24,356,007 invested under this policy and we are currently
earning interest at an effective rate of 4.08% (2006 – 3.56%).

OTHER MD&A REQUIREMENTS

We have 41,120,748 common shares outstanding at April 26, 2007. If all of
our warrants (4,972,000) and options (3,537,950) were exercised we would have
49,630,698 common shares outstanding.

                        NOTES TO FINANCIAL STATEMENTS

    March 31, 2007 (unaudited)


    1.  ACCOUNTING POLICIES

    These unaudited interim financial statements do not include all of the
    disclosures included in the Company's annual financial statements.
    Accordingly, these unaudited interim financial statements should be read
    in conjunction with the Company's most recent annual financial
    statements. The information as at and for the year ended December 31,
    2006 has been derived from the Company's audited financial statements.

    The accounting policies used in the preparation of these unaudited
    interim financial statements conform with those used in the Company's
    most recent annual financial statements except the following:

    Adoption of New Accounting Policy

    Financial Instruments

    On January 1, 2007, the Company prospectively adopted, without
    restatement, CICA Handbook section 3855 "Financial Instruments -
    Recognition and Measurement" and section 1530 "Other Comprehensive
    Income". 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, at the beginning of the year, 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.

    Financial Assets

    Financial assets comprise of cash and cash equivalents, accounts
    receivable (mainly goods and service tax receivable), and short-term
    investments.

    Cash and cash equivalents

    Cash and cash equivalents consist of cash on hand and balances with the
    Company's bank including interest bearing deposits.

    Short-term investments

    The Company determines the appropriate classification of its short-term
    investments at the time of purchase and reevaluates such designation as
    of each balance sheet date. Short-term investments can be classified as
    held-for-trading, available-for-sale or held-to-maturity. Currently, the
    Company has classified all its short-term investments as held-to-maturity
    as it has the positive intent and ability to hold the securities to
    maturity. Held-to-maturity securities are stated at original cost,
    adjusted for amortization of premiums and accretion of discounts to
    maturity computed under the effective interest method. Such amortization
    and interest on securities classified as held-to-maturity are included in
    interest income.

    3.  STOCK BASED COMPENSATION

    As the Company is following the fair value based method of accounting for
    stock options, the Company recorded compensation expense of $21,396
    (March 31, 2006 - $36,833) for the period with respect to the vesting of
    options issued in prior periods with an offsetting credit to contributed
    surplus.

    On February 1, 2007, the Company granted 100,000 options with an exercise
    price of $3.28 (the market price at the date of grant) to its recently
    appointed Vice President of Intellectual Property. These options are
    conditional upon an increase in the Company's option pool which the
    Company presently expects to occur at the Annual General Meeting on
    May 2, 2007. As a result, no compensation expense has been recorded with
    respect to these options during the three month period ending March 31,
    2007.

    7.  SHORT-TERM INVESTMENTS

    Short-term investments, mainly consisting of government of Canada
    treasury bills, 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.

                                                                   Effective
