The Street View image of the bridge shows a school bus driving under it with little in the way of clearance. Also in that image is the clearance height, which is 10ft, 9in.
Jass, not that Canadians are of the "utmost importance" but, like any article, it is written for a specific market, a market where people might be concerned that someone they know might be on it. In fact, I heard about it through a Canadian I know living in New York who frequently takes Megabus between New York and Toronto.
Furthermore, if you notice, about 15.5 hours passed between the story's initial publication and the edited version we see now. Meaning they probably already covered the basics of the crash in previous copies but once it was clear that no one of the same nationality of the market to whom this article was written was killed, they updated it to reflect that.
It's exactly the same as when American press highlights that no Americans are killed when a plane goes down in Thailand, for example.
