                            CERTIFICATION PURSUANT TO
                     SECURITIES EXCHANGE ACT RULE 13A-14(A)

I, Jacques Bedard, certify that:

1.   I have reviewed this annual report on Form 20-F of ART Advanced Research
     technologies Inc. ("Registrant");

2.   Based on my knowledge, this annual report does not contain any untrue
     statement of a material fact or omit to state a material fact necessary to
     make the statements made, in light of the circumstances under which such
     statements were made, not misleading with respect to the period covered by
     this annual report;

3.   Based on my knowledge, the financial statements, and other financial
     information included in this annual report, fairly present in all material
     respects the financial condition, results of operations and cash flows of
     the Registrant as of, and for, the periods presented in this annual report;

4.   The Registrant's other certifying officer and I are responsible for
     establishing and maintaining disclosure controls and procedures (as defined
     in Securities Exchange Act Rules 13a-15(e) and 15d-15(e)) for the
     Registrant and have:

     (a)  designed such disclosure controls and procedures, or caused such
          disclosure controls and procedures to be designed under our
          supervision, to ensure that material information relating to the
          Registrant, including their subsidiaries, is made known to us by
          others within those entities, particularly during the period in which
          this annual report is being prepared;

     (b)  [Paragraph omitted pursuant to SEC Releases Nos. 33-8238 and 34-47986]

     (c)  evaluated the effectiveness of the Registrant's disclosure controls
          and procedures and presented in this annual report our conclusions
          about the effectiveness of the disclosure controls and procedures, as
          of the end of the period covered by this report based on such
          evaluation; and

     (d)  disclosed in this annual report any change in the Registrant's
          internal control over financial reporting that occurred during the
          Registrant's most recent fiscal quarter that has materially affected,
          or is reasonably likely to materially affect, the Registrant's
          internal control over financial reporting; and

5.   The Registrant's other certifying officer and I have disclosed, based on
     our most recent evaluation of internal control over financial reporting, to
     the Registrant's auditors and the audit committee of the Registrant's board
     of directors:

     (a)  all significant deficiencies and material weaknesses in the design or
          operation of internal control over financial reporting which are
          reasonably likely to adversely affect the Registrant's ability to
          record, process, summarize and report financial information; and

     (b)  any fraud, whether or not material, that involves management or other
          employees who have a significant role in the Registrant's internal
          control over financial reporting.
