IMO, that canopy should never have been built in the first place. A well designed public square doesn't need to be artificially enclosed by a canopy. It has the effect of isolating the square from Dundas Street, which is the opposite of what a square should do. The enclosure should come from the surrounding buildings, not a structure along the edge. That and the lack of a central focal point in the square makes it awkward place to spend time. It's almost as if the designers of public squares in Toronto have never spent time in squares in the rest of the world.
