Quebec City, Quebec, October 25, 2005

CGI Group Inc. (CGI) (TSX: GIB.SV.A; NYSE: GIB), today announced the signing of a two-year project valued at CDN$20 million for the adapting and integrating of information technology and accounting systems related to the Quebec Goods and Services Tax (QST). By October 2006, the ministère du Revenu du Québec (Quebec's revenue ministry) will adapt more than 20 systems to coordinate them with those of the Canada Revenue Agency (CRA). The systems pertain mainly to accounting, audits, client account management, security and electronic data exchange.

As part of the contract, CGI will be responsible for guiding Revenu Québec professionals in modifying the ministry's QST management systems; participating in the development of CRA systems, primarily with respect to systems documentation, forms and letters; training thousands of Revenu Québec users; and aligning Revenu Québec processes and systems with those of the CRA. CGI will be supported in this work by its partner Systématix.

Pierre Turcotte, senior vice-president and general manager, Quebec, for CGI said: "We are very proud of our team and their dedication to the Ministry. Having an in-depth knowledge of our clients' infrastructure and business is key for us as we know what ramifications these modified systems will have on their existing infrastructure. We are committed to serving the government sector and want to continue to be seen as their partner of choice."
