Protection of personal information

The Commission d’accès à l’information du Québec reminds public organizations that certain provisions of the Act to modernize legislative provisions respecting the protection of personal information in the private sector, also known as Bill 25, came into force on September 22, 2022. This reform modernizes the rules protecting personal information in Québec, so that they are better adapted to the new challenges posed by today’s digital and technological environment.

To this end, please consult our new Privacy Policy. Politique de protection des renseignements personnels.

Throughout the year, training on the main issues covered by Law 25 will be deployed to all CGTSIM staff.
