Thank you very much.
In my opinion, the solution is quite simple. Amendments are made by exchanging letters, as was done when Revenue Canada became the Canada Revenue Agency.
Ms. Laroche, you were saying that most benefit programs that the agency administers for other departments and agencies, such as the guaranteed income supplement, the GST rebate and the Canada child benefit, are based on the information in tax returns. You state that, since a return has to be produced to show eligibility for the benefits, it is not possible to administer those benefit programs without tax information.
If the agreement between Quebec and Canada allows Quebec to send to Ottawa a copy of the tax information for its taxpayers, will the agency have the information it needs about their previous years' income, which it uses as a basis for paying out the benefits? Does it have any reason to believe that Quebec would not be able to comply with an agreement between Quebec and Canada on exchanging information?
