Quebec's access to information legislation applies to the government, the National Assembly, the lieutenant-governor, the Conseil exécutif—or executive council—and the Conseil du trésor—or treasury board. They can, however, invoke restrictions to protect certain kinds of information, for instance, involving parliamentary privilege. I know that's something that was discussed with Ms. Legault.
The act contains a provision protecting certain decisions made by the executive council or treasury board. It lists the documents that are protected, such as certain communications between ministers or between a minister and the executive council or treasury board, and the records of the deliberations of the executive council or a cabinet committee. If you'd like more detail on the information covered by the restrictions, you can consult sections 30 and 33 of the access to documents act.
As regards the office of a minister, section 34 of the act protects information for the exclusive use of a minister in the exercise of their political role, as opposed to their role as the head of a department. That's how I would summarize the safeguards in that respect and the way they are interpreted.
