I don't know much about these particular buildings, but they don't seem to comply with the City of Toronto's Bird-friendly Development Guidelines.
Does anybody know what EPA (referred to in article) is? The initials could stand for Environmental Protection Act, but I didn't know we in Canada had one of those. We do have a federal Migratory Birds Convention Act, but it seems to be more about what you can't hunt than how you must build sensibly.
