For Immediate Release
September 20, 2005

WINNIPEG, CANADA - CanWest Mediaworks Inc. announced today, in response to
shareholder and analyst inquiries following the announcement yesterday evening
by the Minister of Finance, that the prospectus offering of securities of
CanWest Mediaworks Income Fund is not affected by the Minister's announcement
and the Government`s moratorium on income tax rulings respecting flow-through
entities. The proposed transaction is not predicated on receiving an advance
income tax ruling, nor has one been requested. The prospectus offering is
proceeding as planned.

This news release contains certain comments or forward-looking statements that
are based largely upon the Company`s current expectations and are subject to
certain risks, trends and uncertainties. These factors could cause actual future
performance to vary materially from current expectations.

The Fund's units have not been, and will not be, registered under the United
States Securities Act of 1933, as amended, and may not be offered or sold in the
United States absent registration or the availability of an applicable exemption
from the registration requirement of such Act. The Fund's units are being
offered only by means of the preliminary prospectus. This news release does not
constitute an offer to sell or the solicitation of any offer to buy, nor shall
there be any sale of the Fund's units in any province, territory state or
jurisdiction in which such offer, solicitation or sale would be unlawful prior
to registration or qualification under the securities laws of any such province,
state or jurisdiction. This news release is neither an offer to purchase nor a
solicitation of an offer to sell notes of CanWest Media Works Inc.

CanWest Mediaworks Inc. is a wholly-owned subsidiary of CanWest Global
