TORONTO -- Following a frosty couple days, U.S. President Donald Trump has once again hinted at a possible trade spat with Canada and other NATO countries that he believes aren鈥檛 鈥減utting up their money鈥 on defence spending.

Trump spoke in Washington, D.C. on Thursday in front of representatives ofthe United Nations Security Council and said he had a productive meeting with the leaders of the nine countries who already spend two per cent of their gross domestic product on defence.

鈥淪ome (countries are) really not close and we may have to do something with trade,鈥 he said at the meeting. 鈥淚t鈥檚 not fair that they get U.S. protection. They鈥檙e not putting up their money.鈥

In 2014, all 29 NATO countries agreed to increase defence spending to two per cent of their GDP. Canada currently spends just 1.31 per cent of its GDP on defence and does not have a timetable to reach the two per cent milestone, though the government intends to reach 1.4 per cent by the 2024-2025 fiscal year.

On Dec. 3, Trudeau and Trump met in London at the NATO summit, where Trump called Canada 鈥渟lightly delinquent鈥 on defence spending and when pressed on the matter, Trudeau first said he was committed to spending more and then told Trump that Canada was at 1.4 per cent.

This exchange began a tense few days between the two as Trudeau was later caught on camera talking about Trump to French President Emmanuel Macron, among other world leaders.

Trump went to call Trudeau 鈥渢wo-faced鈥 the next day. His son Donald Trump Jr. also weighed into the matter, of Trudeau in blackface while agreeing with his father that Trudeau is 鈥渢wo-faced.鈥

Speaking on CTV鈥檚 Power Play on Thursday, Deputy Prime Minister Chrystia Freeland sidestepped a question about whether the exposed conversation had hurt relations between Canada and the U.S.

鈥淲e did have some difficult conversations along the way, but have developed a really effective working relationship,鈥 she said. 鈥淚 think we would agree that the current U.S. administration (and) the current government of Canada disagree about a lot of things and we鈥檙e candid with each other about that.鈥
