EXHIBIT 5

                           "BARE" INTERIM CERTIFICATE
   Form 52-109FT2 - Certification of Interim Filings during Transition Period

I, John Maguire, Chief Financial Officer, certify that:

      1.    I have reviewed the interim filings (as this term is defined in
            Multilateral Instrument 52-109 Certification of Disclosure in
            Issuers' Annual and Interim Filings) of CanWest Global
            Communications Corp., (the issuer) for the interim period ending May
            31, 2005;

      2.    Based on my knowledge, the interim filings do not contain any untrue
            statement of a material fact or omit to state a material fact
            required to be stated or that is necessary to make a statement not
            misleading in light of the circumstances under which it was made,
            with respect to the period covered by the interim filings; and

      3.    Based on my knowledge, the interim financial statements together
            with the other financial information included in the interim filings
            fairly present in all material respects the financial condition,
            results of operations and cash flows of the issuer, as of the date
            and for the periods presented in the interim filings.

Date: July 14, 2005
