Freeland said she spoke with U.S. Trade Representative Robert Lighthizer over the weekend after their talks ended on Friday, and their teams have had "a lot of contact" since then.
Freeland will head back to Canada for government business and to report to Canadian Prime Minister Justin Trudeau what transpired during the day's talks and where the negotiations stand.
Trudeau and his ministers will hold a caucus retreat in Saskatoon, Saskatchewan, to plot their strategy.
Canada and the United States have been negotiating since August 28 after Washington unveiled a proposed North American free-trade deal with Mexico and pressed Canada to sign on or be left out. The United States and Mexico reached an agreement on overhauling NAFTA at the beginning of last week, turning up the pressure on Canada to agree to new terms. While Reuters reported on Tuesday that Canada is prepared to make concessions on the issue, it is likely to face opposition among supporters of Trudeau's Liberal Party in Ontario and Quebec.
Wiens declined to say what action the organization would take if an updated NAFTA deal gave the USA a greater chunk of the Canadian market, but did not rule out campaigning against ratification of the agreement, or the Liberal government. "Nafta has been the worst trade deal ever".
Freeland said on Friday she and Lighthizer were making "very good progress" in talks to save NAFTA amid increasing Canadian optimism that a deal can be reached.
Meanwhile, despite the "several" issues still in dispute, there is strong will on the USA side, especially, to wrap up the talks by Friday, trade lawyer Dan Ujczo said Monday.
Freeland also appeared at the women's summit Monday, while Lighthizer was overseas to meet with European Union Trade Commissioner Cecilia Malmstrom.
The two sides have so far been unable to resolve their differences over USA access to the Canadian dairy market, a cultural exemption for Canada and the Chapter 19 dispute resolution mechanism.
USA officials say time is running out to reach a deal that the current Congress can vote on. Under U.S. trade negotiating laws, a text for that agreement is due by October 1.
A late day comment from Pres. Trump boosted the precious metal and the Canadian dollar where he said "Trade talks going well".
"I think this is a complicated time for employees".
It is unclear how long the current round of talks will go on in Washington.
"There's an opportunity to update NAFTA and we're happy to do it, but as I've said it has to be the right deal, it has to be a good deal", he said. "I can't read the tea leaves, but. coming back and saying, "Sorry, we couldn't get an agreement" is just too hard politically to manage" on both sides, Sosnow said.
