The Financial Post reports in its Tuesday edition that the threat of widespread U.S. tariffs is forcing some Canadian companies with operations on both sides of the border to consider shifting production or relocating to the U.S. The Post's Serah Louis writes that last week, Montreal-based TFI International came under scrutiny after announcing it planned to change its legal domicile to the U.S., but the proposal drew the ire of the Caisse pension fund, one of its biggest shareholders. The trucking company has since said it will stay. KPMG found that nearly half of Canadian businesses had plans to shift investments or production to the U.S. to serve the U.S. market and reduce costs in the event that sweeping 25-per-cent U.S. tariffs on Canadian goods are implemented, though so far few have followed through. "I think the threat of tariffs have got Canadian companies exploring and investigating potential shifts in operations from Canada to the U.S., but I'm yet to see a lot of tangible evidence of companies actually doing it at this stage," said KPMG's Lachlan Wolfers. He added that it would not make sense for Canadian companies to shift their operations to the U.S. entirely if most of their customer base lies in Canada.
