Canada wants to change a bilateral agreement to allow it to turn back thousands of asylum seekers walking across the border but the United States is not cooperating, according to a Canadian official with knowledge of the discussions.
Under the Safe Third Country Agreement, or STCA, asylum seekers who arrive at a formal Canada-U.S. border crossing going in either direction are turned back and told to apply for asylum in the first country they arrived in.
Canada wants the agreement rewritten to apply to the entire border.
