EXHIBIT 31.1
            CERTIFICATION OF THE CHIEF EXECUTIVE OFFICER PURSUANT TO

SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

I, Peter Katevatis, Chief Executive Officer, certify that:

(1)      I have reviewed  this  quarterly  report on Form 10-QSB of  Mediscience
         Technology Corp.;

(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 registrant as of, and for, the periods presented in this report;

(4)      The registrant's  other  certifying  officers 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  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 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)       evaluated the  effectiveness  of the  registrant'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  the  report  any  change  in  the  registrant's
                  internal  control over  financial  reporting that has occurred
                  during  the  registrant's  most  recent  fiscal  quarter  (the
                  registrant's  fourth fiscal  quarter in the case of the annual
                  report) 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 officers 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 (or persons  performing the equivalent
         functions):

         a)       all  significant  deficiencies  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.
