The Globe and Mail reports in its Friday edition that TFI International, Canada's biggest trucking company, says America's trade war is hammering some of its freight volumes and fuelling uncertainty. The Globe's Nicolas Van Praet writes that the tariffs U.S. President Donald Trump has imposed on imports from dozens of countries and the fog about his trade policy intentions are hitting businesses across North America, forcing companies to pull financial guidance and reshape strategy. TFI's specialized truckload unit has been "really affected because our end customers are sitting on the fence waiting to see where this is going to go," TFI chief executive officer Alain Bédard told analysts on a call Thursday. "We're not using our trucks to the full extent because the volumes are not where they normally should be." One particular example raised by the CEO illustrates the point: "If you're a farmer in the U.S. today, you don't know who's going to buy your crop because the Chinese are saying, 'You know what? We're going to buy from Brazil. We're not buying from the U.S. any more.' Then you're not going to buy a tractor. You're not going to buy a combine. You're not going to do anything until you have better visibility."
