I'm curious which goods they have in mind:
(Bloomberg) -- The Trump administration's top trade negotiator suggested the US ought to consider banning some Canadian goods, injecting another threat into a trade dispute between Washington and Ottawa.
...
"Canada has banned the sale of liquor and spirits. We haven't banned anything from Canada. You know, they've capped the type of autos we can bring in, they've banned certain goods and services from procurement in the provinces," US Trade Representative Jamieson Greer said in an interview with Canadian Broadcasting Corp. on Wednesday.
"Canada" hasn't banned the sales. Most of the provinces did.
The funny thing is that I bet they haven't thought about it. I'm sure the Canadians have had the "break glass in case of Donald" binders prepared for various contingencies for awhile. That's why they can quickly figure out how to cause the maximum pain (hitting important employers in swing states and small but critical supplies). I bet the Trumpers didn't make a plan.
