Dozens are protesting the U.S./Canada Safe Third Country Agreement (STCA) after the deaths of eight migrants, including two Canadian children, trying to cross the border. The STCA requires migrants seeking asylum in the U.S. or Canada to apply in the country where they first arrive, and the recent amendment covers the entire land border. Critics argue that the agreement forces migrants to attempt crossing through deadly, informal routes and reduces their opportunities for refuge in Canada. Protesters demand an end to the STCA and permanent residency for all migrants. Canada’s Supreme Court is considering a constitutional challenge to the agreement.
