I put niagra, qaida and canada into a google search and came up with a terrorism vulnerability? site, but it has niagras peace bridge as a vulnerable at all times place.

Sites, primarily of economic significance, that are vulnerable at all times include:
Nuclear and intelligence facilities at Chalk River (Ontario).
Peace Bridge in Niagra Falls (Ontario).
Ambassador Bridge connecting Windsor (Ontario) and Detroit (US).
Syncrude production facility in Fort McMurray (Alberta).
Nuclear facility at Point Lepreau (British Columbia).
Nuclear facility at Pickering (Ontario).
