That requires changing the regulations for all CCPCs, and would prevent income splitting for all families that own an incorporated business, as well as medical professionals who own a genuine practice with an office and employees. Sauce for the goose is sauce for the gander.
BTW, income splitting is available fro any self employed person who chooses to incorporate. There plenty of IT professionals, accountants, architects and caterers who do this. Any contractor can do it. Your main hand up seems to be that doctors are making 400k, paid by the province and they benefit from incorporation. If they were paid privately or making 100k, would we be having this discussion?
