The bill is very similar, if not exact, to the Canada Business Corporations Act and the Canada Cooperatives Act in that the act itself does not define what the accounting standards are. It really doesn't care. But to the extent that there's a coexistence of corporate entities within a province, it defers to the provincial authorities to make whatever rules or licensing arrangements are required to provide public accounting services within that province.
If the provinces, either through Bill 46 in Quebec or the Public Accounting Act in Ontario, decide to allow CGAs to do public auditing within the confines of the province, it will automatically allow them to do federal incorporations.
