Julie Taub, an immigration and refugee lawyer, claims that, since the introduction of the agreement in late 2004, the Canada Border Services Agency has lost its capacity and would be "overwhelmed" if the agreement were repealed. Since the beginning of January 2017 and up until the end of March 2018, the RCMP have intercepted 25,645 people crossing the border into Canada at places other than official border checkpoints, with "Roxham Road", near the route between Plattsburgh, New York and Montreal the busiest, becoming a proxy name for this trend. Public Safety Canada estimates another 2,500 came across in April 2018 for a total at just over 28,000. As of early 2019, over 40,000 people crossed into Canada from the United States since early 2017.
