Donald Trump threatened Canada with 25% tariffs and even quipped about a merger of the two nations. The North American neighbors have strong economic links, so what could be the impact of a trade dispute?

Donald Trump's increasingly strident approach to relations with Canada is provoking fear about the potential consequences north of the border and questions about just how serious the U.S. president-elect actually is.

President-elect Trump proposed making Canada the 51st state, citing $200–250 billion in US subsidies and low NATO contributions. PM Trudeau earlier dismissed the remarks as a distraction, reaffirming sovereignty and warning of countermeasures if tariffs are imposed.

Outgoing Canadian Prime Minister Justin Trudeau offered a behind-the-scenes glimpse into President-elect Donald Trump’s recent comments about annexing Canada. During an MSNBC interview Thursday, Trudeau revealed that the matter of annexation came up as a topic of discussion during his visit with Trump at Mar-a-Lago in November.

Surveys show most Canadians prefer staying separate, though some see potential power in a merger. What would it look like if Canada joined the U.S.?

Canada’s leaders clap back at U.S. president-elect Donald Trump after he again said he’ll make Canada the 51st state of the United States.

The president-elect said he'd use "economic force" to bring Canada into the US while also saying the Northern neighbor had nothing the US needs.
