Do you really believe what you wrote here? Tariffs are to spur domestic product sales, by making foreign cheap crap harder to dump into the local market place by raising their costs to the approx. same price as domestic product. In this way the shopper decides on quality and loyalty over price, of course you knew that and were just playing silly bugger right.
The revenue from the Tariffs of course are put into the general revenue of the government like all other taxes.
As far as Trudeau goes he hasn't got a clue what is right for Canadians in the market place until somebody tells him what he needs to do and why he needs to do it.
