SAINT-GEORGES-DE-CLARENCEVILLE (Reuters) - Six Lego-like concrete blocks mark the end of a rural road at the U.S.-Canada border. The police vehicle, revving through blowing snow, crunches to a stop.

The barriers, installed last August in a joint venture with President Joe Biden's administration, stop vehicles bearing migrants from barreling across the border into the United States.
