    CERTIFICATIONS PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002.

I, John K. Sheppard, certify that:

     1.   I have reviewed this quarterly report on Form 10-Q of Cott
          Corporation;

     2.   Based on my knowledge, this quarterly 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 quarterly report;

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

     4.   Cott Corporation's other certifying officer 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)) for Cott
          Corporation 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 Cott
               Corporation, including its consolidated subsidiaries, is made
               known to us by others within those entities, particularly during
               the period in which this quarterly report is being prepared;

          (b)  evaluated the effectiveness of Cott Corporation's disclosure
               controls and procedures and presented in this quarterly 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

          (c)  disclosed in this quarterly report any change in Cott
               Corporation's internal control over financial reporting that
               occurred during Cott Corporation's third fiscal quarter that has
               materially affected, or is reasonably likely to materially
               affect, Cott Corporation's internal control over financial
               reporting; and

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

          (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 Cott
               Corporation'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 Cott Corporation's
               internal control over financial reporting.
