Canada said on Wednesday that it would need to see movement from the United States if the two sides are to reach a deal on renewing NAFTA, which Washington insists must be finished by the end of the month.
Although the administration of U.S. President Donald Trump and its allies are increasing pressure on Canada to make the concessions they say are needed for the North American Free Trade Agreement, Canadian Prime Minister Justin Trudeau made clear he also wanted to see flexibility.
"We're interested in what could be a good deal for Canada but we're going to need to see a certain amount of movement in order to get there and that's certainly what we're hoping for," he told reporters in Ottawa.
Shortly afterwards, Canadian Foreign Minister Chrystia Freeland met U.S. Trade Representative Robert Lighthizer for their fourth set of talks in four weeks with the two sides still disagreeing on major issues.
Trump has already wrapped up a side deal with Mexico and is threatening to exclude Canada if necessary. Canadian officials say they do not believe the U.S. Congress would agree to turn NAFTA into a bilateral treaty.
U.S. Chamber of Commerce President Thomas Donohue said it would be extremely complicated, if not impossible, for the administration to pull off a Mexico-only agreement.
"If Canada doesn't come into the deal there is no deal," Donohue told a media breakfast in Washington.
Donohue said he believed that if the administration wanted to end the current NAFTA, such a move would be subject to a vote in Congress, which would be difficult to get.
The Chamber, the most influential U.S. business lobby, wants NAFTA to be renegotiated as a tri-lateral agreement, citing how highly integrated the three member nations' economies have become since the pact came into force in 1994.
Negotiators are arguing over cultural protections, dispute resolution, and a U.S. demand for more access to Canada's protected dairy market. Sources say Ottawa has made clear it is prepared to make concessions, which would anger the influential dairy lobby.
"For American farmers the Canadian market is a drop in the bucket. For us it's our livelihood," Dairy Farmers of Canada vice president David Wiens told reporters in Ottawa. Concessions in past trade deals had already hurt Canadian farmers, he said.
"The dairy sector cannot be negatively impacted again by a new trade agreement," he said. "Enough is enough."
