The Financial Post reports in its Friday, Jan. 10, edition that National Bank economist Warren Lovely says Canada must resolve its political uncertainty as quickly as possible to effectively address the challenges posed by incoming U.S. President Donald Trump. The Post's Jordan Gowling writes that Mr. Lovely says: "Let's work toward establishing a strong position with a clear mandate from Canadian voters to our parliamentarians. This clarity is essential for our federal and provincial governments to implement the necessary policies to address today's risk factors, with Trump being the primary concern." On Monday, Prime Minister Justin Trudeau announced his resignation. The country is in a state of uncertainty just as Mr. Trump, who has threatened to impose 25-per-cent tariffs on Canadian and Mexican goods, is preparing to take office. McGill University public policy professor Christopher Ragan says that while he believes the Bank of Canada will be forced to cut rates, there is not much it can do to address the kind of shock that tariffs of that magnitude would have on the Canadian economy. Mr. Ragan said, "Lower the interest rates all you want, it's probably not going to stimulate much investment."
