Mr. Camilleri announced also today a number of senior executive appointments at
CanWest MediaWorks. With these appointments, CanWest MediaWorks has assembled
some of the best global talent to lead the company's Canadian media operations
in sustained growth and to meet the challenges in what may be the world's most
competitive and sophisticated media market.

MS. KATHLEEN A. DORE is appointed to the position of President Television and
Radio, CanWest MediaWorks and MICHAEL G. WILLIAMS is named President,
Publications, CanWest MediaWorks. Both appointments fill positions that have
been vacant since early in 2003. JOSEPH T. MANGIONE is appointed to the position
of President, Sales and Marketing, CanWest MediaWorks. Biographical information
on each of the new executives is contained in the backgrounder attached to this
release.

"The world has changed and the ingredients for success are different," said Mr.
Camilleri. "We know that growth only comes when we focus on the customer.
Today`s customers choose how, when, and where, they receive news, information,
and entertainment. We are going to excel in giving them that choice with
superior service."


                                                                               1

"The company has achieved much since it launched the integration of its greatly
expanded portfolio of media assets acquired in 2000," Camilleri continued. "More
efficient and lower cost operations, integrated sales and marketing teams, and
the introduction of new and complementary businesses including radio stations,
music marketing and distribution, and book publishing have been important
milestones in our strategy to date. CanWest MediaWorks is now the industry
leader in cross-media advertising and multi-media sales and marketing campaigns.
These activities increase revenues, support newspaper circulation and increase
television ratings. We are confident that we have the foundation of history,
talent, and critical experience to continue to win in the marketplace," Mr.
Camilleri stated.

In welcoming the new executives, Mr. Camilleri spoke of CanWest MediaWorks'
important innovation and growth opportunities going forward. "Looking ahead, our
priority is to adapt our publishing businesses to reflect changing consumer
demands and readership trends through the introduction of new products and
digitized delivery systems - more choices, superior service."

"The number one priority of our broadcasting operations is to address challenges
to the conventional television business model posed by the proliferation of new
specialty television channels and certain regulatory advantages they currently
enjoy," added Mr. Camilleri. "In that regard we will continue to make
significant investments in new programming to boost ratings and increase
revenues at Global. We will generate more Canadian television production,
including profitable news and information programming. CanWest MediaWorks will
continue to build the subscriber and advertising base of its successful new
digital television channels while actively looking at opportunities to launch
new channels and to expand its position in Canadian radio. CanWest MediaWorks
will also launch new business units in the coming months as we evolve to a
customer focused content and marketing company," said Mr. Camilleri.

"With our world-class leadership, CanWest MediaWorks will continue to deliver on
its growth strategy - to offer more innovative and superior products to its
customers at lower costs, to advance the competitive position of our publishing,
broadcasting, and interactive operations, and to strengthen the company's
financial performance for the benefit of our shareholders," added Mr.
Camilleri.

Mr. Camilleri announced a number of additional appointments to the new CanWest
MediaWorks executive team, the details of which are also included in the
attached backgrounder. These appointments, which fill existing vacancies or are
in anticipation of planned retirements, will further the integration of
CanWest's Canadian media operations, which began in 2003 when the management of
CanWest's Canadian newspaper, television and interactive operations were
combined into one business.

Also commenting on today's announcements, CanWest President and Chief Executive
Officer Leonard Asper said, "I am delighted to welcome this addition of talent
to CanWest MediaWorks. These appointments are the result of an extensive
executive search in Canada and elsewhere to identify and recruit the best global
talent to help us realize our vision to become a top-ranking international media
company. The three essential ingredients for our successful growth strategy are
securing the right people at all levels, generating or acquiring superior
content, and using the best technology to deliver that content to consumers how
and when they want it. These additions to our management team at CanWest
MediaWorks represent an important milestone in ensuring that CanWest continues
to move forward on all those fronts," Mr. Asper added, "Over the past four years
we have fully digested the two major acquisitions that the company made in 2000.
We have completed the integration of our operations, and realized the resulting
efficiencies. Now it is time for us to address the structural challenges to our
mature businesses, drive forward our

                                                                               2
