My point is people care more about where their cars are made, and they don't even really care about that.
Even if people wouldn't normally care, they will care now because of the publicity and bidding process that has taken place. People in cities who do not win will be upset when they lose, and people everywhere, including places that were never in the running, will be upset if they put the office in Canada. You must not have heard of the "America first" line of thinking that got trump elected, in part.
This will blow over in months and be totally forgotten.
But on the other hand, if they want to run a PR campaign on the basis of "we seriously considered many US cities, and Toronto was a better option", they're certainly putting in the groundwork for that.
