It shouldn't cost you much to pass it along, so why would you defy the request of the current finance minister? Wouldn't you be expected to say with the perceived conflict of interest—not just the real ones, but the perceived one—that your board member has in being the inserted finance minister between the Prime Minister and the current finance minister, “You know what? Maybe we should be careful since the Canadian part of our business is small and this is a minuscule amount of that business and we should comply.”
Or is it that you're just too greedy to screw Canadian small businesses that you'll take every dollar out of them? As you are an American-based company, you don't really care about the Canadian market, and neither does your board member. You would have thought your board member, Mark Carney, would have said: “Hey, guys, this does matter. You shouldn't do this reputational harm to the company.” Is he that detached as a board member that he doesn't actually care about what's going on in his own country?
