As Canadian border agents are set to strike as early as June, Minnesota officials are on alert. 

Canadian border agents voted 96% in favor of going on strike, according to Mark Weber, the president of Canada’s Customs and Immigration Union. The strike could bring traffic to a standstill at border crossings along the larger than 5,000-mile U.S.-Canadian border. Officials in Minnesota, a state home to eight border crossings and 547 miles of a shared border with Canada, are preparing for the strike.
