Beware the 3rd floor. I know of at least one person who found bedbugs there.
A quick google search shows that this library has had bed bug reports since 2010 at least. Not surprising seeing the enormous number of universtity students that study there (they probably bring them in from their dorms, which have had a problem with bedbugs the past couple years).

According to CityNews and Toronto Star reports and staff who work there, this location (the Metro Toronto Reference Library) has bedbugs.
