Please, Withdrawing from trade with the United States would result in Canada being a failed state overnight, exporting commodities and low grade manufactured goods to the United States is the only thing propping this "country" up.
In the end, we are Americans, we're simply the United Empire Loyalists, up until 1812, there wasn't even a border between us, the people here called themselves "Americans", the only "Canadians" at the time were in Quebec, and in actual fact, even during that seminal war, trade between the Canada's and the United States not only continued completely unabated, it actually increased, the Americans in New England were actually supplying the proto-Canadians with goods to keep them in the fight, because they opposed the war and favoured friendly relations and trade with Britain, James Madison be damned.
Trump is no Madison, he's more Jacksonian, bombastic perhaps, chauvinistic to be sure, but no threat to us. As to the Mueller Witch Hunt, if the Democucks try to impeach, Trump will simply become more powerful, trying to overthrow the will of the electorate in America is a big mistake, impeaching Nixon simply led to Ronald Reagan, Newt Gingrich and Clintonian Triangulation. Trying to bring Trump down by any means other than election, will cripple the Democrats for generations to come.
