U.S. President Donald Trump says he is "terminating all discussions on trade with Canada" and threatening new tariffs over Ottawa's plans to push ahead with a digital services tax at the end of the month.
Trump says Washington will notify Canada about new tariff rates required "to do business with the United States" within the next week.
Trump made the comments in a post on his social media account this afternoon, calling it a "direct and blatant attack on our country."
