Montreal, Quebec, September 27, 2006

CGI Group Inc. (CGI) (TSX: GIB.A; NYSE: GIB), a major supplier of information
technology services to the public sector and one of the largest independent
information technology (IT) and business process services firms in the world,
announced today three contract signings in Western Canada totalling more than
$20 million. The contracts, covering both municipal and provincial jurisdictions
have been signed with the following entities:

• City of Calgary - an
enterprise service desk for a three year contract with an option for two
additional two year agreements

• British Columbia Ministry of Health - a
five year contract to provide application and server management
services

• Alberta Ministry of Health and Wellness - a four year contract
to provide Business Intelligence Environment (BIE) services

“These three
contracts show the diversity of CGI’s end-to-end offerings for the public
sector,” said Bill Clark, Senior Vice President of CGI for Western Canada. “We
are very proud of our long-term partnership with Alberta Health and Wellness and
welcome two new outsourcing clients - the City of Calgary and BC Health - to the
fold.”

For the City of Calgary, CGI will be providing an enterprise
service desk on a 24/7 basis supporting all IT related issues. The call center
will handle all technology support calls from City staff starting on November 1,
2006.

Beginning on October 1, 2006, CGI will provide the British
Columbia Ministry of Health with management of servers and support of selected
computer applications including BC ambulance services, home and community care,
population health and wellness and others.

The Business Intelligence
Environment (BIE) services provided to the Alberta Ministry of Health and
Wellness will allow the department to import data from many of its current
applications to a central data repository and allow better analysis of the
consumption of health care services.

“The Canadian public sector is an
important area of growth for CGI and these three wins are very strategic for
us,” added Bill Clark. “They reflect a trend towards business transformation in
the Canadian public sector. For over thirty years, we have been a major provider
to federal, state, provincial, local and municipal governments in the U.S.,
Canada, Europe and Australia and we are well positioned to help governments
achieve their goals and better serve their citizens.”

With over 5,000
professionals dedicated to the public sector and more than $1 billion in revenue
from this sector, CGI is one of the largest IT and business process services
providers to government in Canada and the United States. The company serves the
majority of federal and 75% of provincial and territorial governments in Canada.
This deep expertise enables public sector clients to modernize and transform
with services and solutions that improve the citizen experience, increase
efficiency and improve accountability.
