When I last visited Toronto (which was some time ago -- 2012), I was struck by not just how much the city was building up, but by how far out from the city center was building towers. Most of the towers were along the lake, and near a highway, but I didn't see much in terms of rail-based public transit or nearby office towers (basically everything being advertised was residential units), so I have two questions:  - How full are those buildings? - Are there significant traffic issues from induced commutes?
