US President DONALD TRUMP has said he had an extremely productive first call with Canadian Prime Minister MARK CARNEY, amid an ongoing trade war between the two neighbours.

In a Truth Social post, TRUMP said that the two will meet immediately after Canada’s upcoming elections on 28 April to discuss politics, business, and all other factors.

CARNEY, currently in the midst of an election campaign, described the call as very constructive, adding that he told the president that Canada will implement retaliatory tariffs to protect Canadian workers.

The call between Carney and Trump, however, is the first since the new prime minister took office on 14 March.
