About 100 police, firefighters and other emergency workers held a disaster-response drill in downtown Toronto's deserted financial district Sunday following a week that saw two soldiers killed on Canadian soil.
Security in normally relaxed Canada has been tighter in the days since a gunman shot dead a soldier in Ottawa before charging into the parliament building and another man ran over two soldiers with a car, killing one, outside Montreal.
Toronto emergency responders donned oxygen tanks and yellow full-body hazardous material suits shortly after dawn, set up decontamination tents and practiced how they would respond in an office tower that had received a suspicious package.
