The Trump administration doesn't have the legal authority to sideswipe Canada and sign a bilateral trade deal with Mexico, Quebec's chief NAFTA negotiator said Monday.

Raymond Bachand, an ex-Quebec finance minister, said "there is no worry whatsoever" the current one-on-one talks between the United States and Mexico will end in a trade deal signed without Canada.

Bilateral NAFTA negotiations between the two countries have been building momentum in recent weeks, while Canada has yet to return to the table this summer.

U.S. President Donald Trump recently stated a deal with Mexico "is coming along nicely" and "Canada must wait."

The president has also said he would be interested in signing separate deals with both countries.

Even if Trump really wanted that, Bachand said, he couldn't get it.

"If the U.S. wanted a bilateral deal — and they don't, they've repeated often they want a trilateral deal — they don't have legal authority.

"They have the authority from Congress to negotiate a trilateral NAFTA deal in a fast-track way — meaning Congress votes yes or no on the final deal once it's been reached. They don't have that (fast-track) authority for a bilateral deal."

Bachand made the comments in Stowe, Vt., during the two-day annual conference between governors of New England states and the premiers of Quebec and the eastern Canadian provinces.

Pleased to welcome my fellow New England Governors and Eastern Canadian Premiers to Vermont for the <a href="https://twitter.com/hashtag/NEGECP?src=hash&ref_src=twsrc%5Etfw">#NEGECP</a> Conference. Looking forward to a productive day discussing shared efforts to strengthen our economies, create jobs, protect the vulnerable and our environment, and more. <a href="https://t.co/aGQCTSrXJJ">pic.twitter.com/aGQCTSrXJJ</a> —@GovPhilScott

Senate, governors will ensure NAFTA continues

Not a single U.S. governor or senator has asked to pull their country out of NAFTA, Bachand said, which is Canada's true trump card in the negotiations, he added.

"So all the so-called modernization attempts the president wants with NAFTA, there is a kind of red line," Bachand said. "NAFTA will continue because the power in the U.S. Senate is very strong in commercial decisions, and governors also have a big influence."

On Sunday, Vermont Gov. Phil Scott and Quebec Premier Philippe Couillard signed a joint declaration on economic co-operation, despite the trade tensions between the two countries.

Today, I signed a Joint Declaration with Quebec Premier Philippe Couillard, demonstrating our commitment to strengthening the Vermont-Quebec bond, and our cooperative efforts to foster economic growth. <a href="https://t.co/GXaQzNdZ3B">https://t.co/GXaQzNdZ3B</a> <a href="https://t.co/VhKfcGOMdC">pic.twitter.com/VhKfcGOMdC</a> —@GovPhilScott

Scott said the agreement "acknowledges our intertwined economies and solidifies our commitment to building cross-border trade."

Couillard said Monday one of the ways a new NAFTA deal will be reached is by convincing Americans who live outside the states that border Canada of how critical trade is for the economies of both countries.

Quebec's premier said he had breakfast with the eastern premiers and New England governors Monday and they "almost exclusively" talked about NAFTA.

"The border states understand well the level of integration of our economies," he said. "It's the rest of the country and the White House we have to work on."
