Bank of Canada Governor Tiff Macklem said on Thursday a policy shift in the U.S. was causing uncertainty and President Donald Trump's tariff threats were already impacting businesses and households.

President Donald Trump put a month-long pause on his planned tariffs on Canadian imports. Earlier in the day, though, he added two new items to his long list of inaccurate complaints about Canada.

Mark Carney, the frontrunner to be the next Canadian prime minister, has said his country is "going to stand up to a bully" after US President Donald Trump said he would unveil tariffs of 25% on Canada. Speaking exclusively to BBC Newsnight, 59-year-old Carney said Canada will "match dollar for dollar the US tariffs".
