The next round of talks on a trade agreement with Canada will be missing a major component.
While a meeting was reportedly expected to be held on Thursday, Canadian Foreign Minister Chrystia Freeland said officials needed to do more work before she could hold fresh talks with the United States.
She went back to Canada earlier this week to personally update Prime Minister Trudeau.
During a phone call with U.S. Trade Representative Robert Lighthizer, Freeland said she would stay in Canada.
Freeland said that officials needed time to hold technical discussions, according to Reuters.

Canada's chief NAFTA negotiator, as well as the country's ambassador to the United States, will reportedly fly back to Washington on Wednesday night for more talks.
