lined up at que border. They were to be towed across by canadian troops as American troops could not be allowed to drive them in. Twas a bit dicey around there then. There was general fear of an armed inssurection, It was also he time the war powers act was passed allowing canadians to be incarcerated without a charge and held for 6 months incommunicado. I dont know if it has ever been specifically recinded.
thanx,
