Nonsense, it is a perfectly reasonable response to the disproportionate, capricious, and possibly-illegal Republican import taxes on Americans (tariffs) that were thrown onto Canadian everything while "joking" about violently annexing Canada.
If Mr. Whiting cared about reasonable and proportional trade, he should be aiming those complaints at his own politicians. He's been maxing out in his donations to the company PAC for the last several years, but I can't tell you for sure what candidates that money went to. [0]
