The trade war initiated by U.S. President Donald Trump is significantly impacting Canadian ports, with Halifax experiencing a 10% drop in container traffic as concerns grow over the fluctuating nature of tariffs. Professor Trevor Heaver predicts a dramatic decline in shipping traffic, particularly affecting the Trans-Pacific trade, and anticipates increased “blank sailings” due to reduced demand. While Vancouver’s port sees a majority of trade with non-U.S. countries, the Port of Prince Rupert is expected to face the most significant challenges, despite recent steady volumes.
