           CANWEST AMENDS PURCHASE PRICE IN ITS PREVIOUSLY ANNOUNCED
          TENDER OFFER FOR ITS 7 5/8% SENIOR UNSECURED NOTES DUE 2013

         Winnipeg, Manitoba, -- CanWest Mediaworks Inc. ("CanWest"), a
wholly-owned subsidiary of CanWest Global Communications Corp., today announced
that it has amended the purchase price in its cash tender offer for its 7 5/8%
Senior Unsecured Notes due 2013 (the "2013 Notes"). This series of debt
securities has an outstanding principal amount outstanding of US$200 million
(CDN$238 million). The purchase price for CanWest's l0 5/8% Senior Subordinated
Notes due 2011 (the "2011 Notes") will remain as originally announced by CanWest
on September 8, 2005.

         The amended purchase price for the 2013 Notes will be a "fixed spread"
price determined on October 6, 2005 (subject to extension), calculated using a
yield equal to a fixed spread of 50 basis points plus the yield to maturity of
the 2.625% US. Treasury Note due May 15, 2008. The purchase price for the 2013
Notes will no longer be a composite price that includes an "equity claw-back"
price component. As a result of this amendment, all holders who validly tender
their 2013 Notes prior to the early tender premium deadline will receive 100% of
the "fixed spread price" (as that term is used in the Offers to Purchase and
Consent Solicitations Statement dated September 8, 2005 that CanWest distributed
to holders of the notes) for their 2013 Notes that are accepted for purchase.
Holders who validly tender their 2013 Notes after the early tender premium
deadline will receive the fixed spread price minus an early tender premium of
US$30.00 per US$l,000 principal amount of 2013 Notes that are accepted.

         All other terms and conditions of the tender offers and consent
solicitations with respect to the notes described above remain the same. For
both offers, the early tender premium deadline for the consent solicitations is
5:00 p.m. Eastern Daylight Time (EDT) on September 21, 2005 and the expiration
time is midnight EDT, on October 12, 2005. Holders may withdraw their tenders of
notes prior to 5:00 p.m. EDT on September 21, 2005. All of these dates are
subject to extension at CanWest's election.

         The tender offers and consent solicitations are made solely by the
Offers to Purchase and Consent Solicitations Statement dated September 8, 2005,
the related letter of transmittal and consent, and any amendments or supplements
thereto.



         The offers are subject to certain conditions, which include the tender
of a set minimum amount of notes of each series and the successful creation and
Canadian initial public offering of CanWest Mediaworks Income Fund.

         CanWest has retained Citigroup Global Markets Inc. to serve as dealer
manager for the tender offers and consent solicitations. Global Bondholder
Services Corporation is serving as the depositary and information agent for the
tender offers and consent solicitations.
