John Furlong says there's already a comprehensive security plan in place. And he says the bombings haven't yet given VANOC a reason to change its strategy.
"We decided quite a long time ago we did not want security to be the story of the 2010 Games. We want this to be about sport and about celebration and about culture and about nation building."
Furlong admits that no one knows for sure who is responsible for the London bombings, or why they targeted the British capital.
But he says he doesn't think it has anything to do with London winning the right to host the 2012 Olympic Game just the day before.
"As the day wound down, it was fairly clear that what happened in London was aimed at the G8 and not at this," says Furlong.
But an international security expert at Simon Fraser University disagrees. Andre Gerelymatos believes attackers might have been attracted by the worldwide attention given London's victory.
"I think another reason they decided on London was that a lot of media was focused about the announcement over the Olympics, and a lot of international media was there."
Gerelymatos also says Canada is a likely target because of its military involvement in the war in Afghanistan and our proximity to the United States.
