With Canada, the United States and Mexico due to sign a new trade pact Friday, the three sides are still finalizing some of the details, Canadian Foreign Minister Chrystia Freeland said on Thursday.

Canada's envoy to the United States was asked for his opinion today - on a scale of one to 10 - whether Ottawa and Washington are likely to strike a new trade deal by a Sunday deadline.

'We're going to make a fairer deal with Canada," the president said. "Just like we did with Mexico."
