**CERTIFICATION**




I,
      R.
      David Anderson, certify that:




1.
      I have
      reviewed this annual report on Form 40-F of CGI Group Inc.;




2.
      Based on my knowledge, this 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 report;




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




4.
      The issuer’s other certifying officer(s) and I are responsible for establishing
      and maintaining disclosure controls and procedures (as defined in Exchange
      Act
      Rules 13a-15(e) and 15d-15(e ))
      and
      internal control over financial reporting (as defined in Exchange Act Rules
      13a-15(f) and 15d-15(f)) for the issuer 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 issuer, including its consolidated
      subsidiaries, is made known to us by others within those entities, particularly
      during the period in which this report is being prepared;




(b)
      Designed such internal control over financial reporting, or caused such internal
      control over financial reporting to be designed under our supervision, to
      provide reasonable assurance regarding the reliability of financial reporting
      and the preparation of financial statements for external purposes in accordance
      with generally accepted accounting principles;




(c) Evaluated
      the effectiveness of the issuer’s disclosure controls and procedures and
      presented in this 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 report any change in the issuer’s internal control over
      financial reporting that occurred during the period covered by the annual report
      that has materially affected, or is reasonably likely to materially affect,
      the
      issuer’s internal control over financial reporting; and




5.
      The issuer’s other certifying officer(s) and I have disclosed, based on our most
      recent evaluation of internal control over financial reporting, to the issuer’s
      auditors and the audit committee of the issuer’s board of directors (or persons
      performing the equivalent functions):




(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 issuer’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 issuer’s internal control over financial
      reporting.
