That's exclusively in the area of federal jurisdiction. The matter of interprovincial trade is exclusively an area of federal jurisdiction, so I don't see any interference with the provinces' jurisdiction on that issue. The federal government is free to legislate as it wants on that issue and in fact, the history of the Importation of Intoxicating Liquors Act is that the provinces asked the federal government to introduce the original IILA in 1928 because they did not have the power to regulate interprovincial trade. So if the federal government chooses to put a particular standard in there, it is certainly free to do so, in my legal opinion.
