The feds are appealing a controversial ruling that struck down an agreement between the United States and Canada regarding refugees.
Since 2004, the Safe Third Country Agreement has made it harder for people seeking refugee status in Canada to pass through the U.S.
Under the agreement, people who are fleeing violence are required to file their claims in the first safe country they arrive in, which includes the U.S.
That means people who land in the U.S. cannot claim status in Canada.
In July, a federal court struck down the law, ruling that parts of it violated a right to life, liberty and security.
However, it is set to remain in place until mid-January.
Public Safety Minister Bill Blair argues that there were errors in the court’s initial findings.
