Ms. Laroche, it was possible to do it for the GST. Indeed, the goal is not necessarily to achieve economies of scale. The primary goal, at least the Conservative Party's goal, is to make life easier for Quebecers. You said yourself that you had initiated discussions to make life easier for Quebecers, but that they went nowhere.
In our view, a single tax return could be processed by both levels of government, and this would not take away from the Canada Revenue Agency's autonomy in its duty to collect taxes and provide services. In fact, I don't see the connection. The Canada Revenue Agency would still have just as much access to the information needed to deliver benefits to Canadians, such as the Canada emergency response benefit. An administrative agreement between the two levels of government would not result in any information being withheld, as far as I know.
Could the Canada Revenue Agency lay out a plan to show us how a single tax return administered by the Government of Quebec could be introduced?
