Agreed, integrated tram lines at street level would work perfectly in Toronto (as they do all around the word).

Toronto just needs to take some streets with tram lines already in them and turn sections of these streets into car free pedestrian zones. Half if not more trams have boarding zones within a full traffic lane already.

Toronto being toronto through would probably screw it up, turning a non issue into a issue, with pedestrian barriers and over engineering of some sort.
