President Trump may have already celebrated the passage of the United States-Mexico-Canada Agreement on trade, but the deal hasn’t yet been ratified by Canada, and it may not be for weeks.

“It is a major economic issue for the regions. We can’t just move on,” Yves-Francois Blanchet, leader of the Canadian Parliament’s Bloc Quebecois, tweeted Thursday. Blanchet promised “developments in the coming days” but gave no further details. Bloc Quebecois and other relatively small opposition groups have used parliamentary procedure to slow the deal.
