Just to clear it up, I'm not a wobbly cyclist. And though I don't speed through intersections, I don't crawl along either like I'm on a one speed cruiser or anything. Just average speed, I guess. I've got a mirror on the bike I use in rougher weather, but I don't find that it works better than shoulder checking.
A former coworker and I would share stories sometimes...she'd been riding in Vancouver for something like ten years, and then she moved here. She was run off the road several times in Toronto.
It also might have soemthing to do with my route, which is a little unavoidable...still, plenty of cyclists use Queen St every day....
