(Adds quotes, details) OTTAWA, Nov 14 (Reuters) - Canada will boost security on major public transit systems in a bid to prevent bloody attacks of the kind that rocked London last year, Transport Minister Lawrence Cannon said on Tuesday. He said Ottawa would spend up to C$37 million ($32 million) on the country's six busiest urban transit systems -- Montreal, Toronto, Ottawa, Edmonton, Calgary and Vancouver. The money will cover the cost of high priority projects such as upgrading security equipment as well as drawing up new security plans and employee training programs. "Canada is not immune to the threat of terrorism. We must remain vigilant and continue to work with our partners in government and industry to address transit security issues," Cannon told a news conference in Montreal. "We feel it's extremely important ... to go to where the risk is the highest, that is to say where there are more people on a daily basis commuting," he said. Cannon later told the Canadian Broadcasting Corp. that Ottawa would, over the next two years, also fund studies of other transit systems across Canada to assess the risks. Osama bin Laden's al Qaeda group has identified Canada as a target for possible attack several times. Canadian troops did not take part in the U.S.-led war on Iraq but are fighting Taliban militants in Afghanistan. In July 2005, four Muslim suicide bombers killed 52 commuters on three subway trains and a bus in London. In March 2004, three blasts killed 191 people in Madrid. "We have seen very tragic incidents in London, Spain and elsewhere. What this money will do is allow us to put cameras throughout our system, in the subways ... in our streetcars and buses," Toronto Mayor David Miller told CBC television. ($1=$1.14 Canadian)
