Wouldn't a simpler method for interprovincial trade be for the federal government to invoke Section 94 of the 1867 Constitution Act, which authorizes the federal government to transfer responsibility for property rights and trade to itself with the consent of the provinces, with only Quebec being exempt from Section 94? As more and more provinces joined, businesses and other third parties could put more and more pressure on the holdouts to join.

Concerns from regions like Alberta about it not taking into account their particular circumstances could be alleviated by placing its national headquarters in some place like Calgary, which would also make sense as being one of the country's leading business hubs?
