Canada's Freeland to travel to Washington tomorrow for NAFTA talks: spokesman

Canada's Foreign Minister Chrystia Freeland will travel to Washington tomorrow to continue efforts to rewrite the North American Free Trade Agreement, a spokesman said today.

Freeland's announcement comes an hour after the US and Mexico announced an agreement to modernize the 25-year-old agreement free trade pact after a year of fraught negotiations.

"As we have said all along, progress between Mexico and the United States is a necessary requirement for any renewed NAFTA agreement," Freeland's spokesman Adam Austen said.

But he said Ottawa would "only sign a new NAFTA that is good for Canada and good for the middle class. Canada's signature is required.
