Prime Minister Justin Trudeau has suggested his country could cut a deal with the U.S. without Mexico.

The leader of Canada's most populous province said Wednesday that all of the country's provincial and territorial governments want Prime Minister Justin Trudeau's federal government to negotiate a bilateral trade deal with the United States that excludes Mexico.

Canada wants Mexico to stay in a continental trade pact despite concerns about China possibly using it as a back door to flood the North American market, a source directly familiar with the matter said on Wednesday.
