A landmark ruling last week found that sending refugee claimants back to the United States under the Safe Third Country Agreement violates their human rights—and a federal judge has given the government six months to fix or terminate the policy. What does this mean for the US-Canada border? For the thousands of refugees every year that arrive in the United States then try to make it to Canada?

To understand this agreement you have to go back to the months after 9/11, when immigration and border security were undergoing massive changes. And to understand why the agreement has been invalidated in court, you need to look at what's changed at the border in the years since then.
