    DISCLOSURE CONTROLS AND PROCEDURES, AND INTERNAL CONTROLS   Pursuant
to the Sarbanes-Oxley Act of 2002 as adopted by the U.S. Securities and
Exchange Commission, management evaluates the effectiveness of the design and
operation of the Corporations disclosure controls and procedures (disclosure
controls) and internal controls for financial reporting (internal
controls).  This evaluation is done
under the supervision of, and with the participation of, the Chief Executive
Officer and the acting principal financial officer).  Disclosure
controls are procedures designed to ensure that information required to be
disclosed in reports filed with securities regulatory agencies is recorded,
processed, summarized and reported on a timely basis, and that management,
including the Chief Executive Officer and the acting principal financial
officer, can make timely decisions utilizing such information.  Internal controls are procedures designed to
provide reasonable assurance that transactions are properly authorized, assets
are safeguarded against unauthorized or improper use, and transactions are
properly recorded and reported.  It
should be noted that the design of any system of controls is based in part upon
certain assumptions about the likelihood of future events, and there can be no
assurance that any design will succeed in achieving its stated goals under all
potential future conditions, regardless of how remote.  Within
90 days prior to the filing of this annual report, management evaluated the
effectiveness of disclosure controls and internal controls.  Based on that evaluation, the Chief
Executive Officer and the acting principal financial officer have concluded
that:  Canadian Superiors disclosure controls are effective in ensuring that
material information relating to Canadian Superior is made known to management
on a timely basis, and is included in this annual report; and  Canadian Superiors internal controls are effective in providing
assurance that the consolidated financial statements for 2002 are fairly
presented.  To
the best of these officers knowledge and belief, there have been no
significant changes in internal controls or in other factors that could
significantly affect internal controls subsequent to the date on which such
evaluation was completed in connection with this annual report, including any
corrective actions with regard to significant deficiencies and material
weaknesses.    3
