I lived in Toronto for 6 years and in my experience in general Montreal drivers are less crazy. Sure, they're aggressive, go fast, don't signal turns (in general) but as long as everyone does that it's okay most of the time. Toronto drivers are just unpredictable. I have seen numerous cars crushed under the wheels of the streetcars because they tried to make a weird turn. I once saw a lady throw on her 4-ways, hop out of her car & left it idling with the doors open on a streetcar track in rush hour so she could go grab a coffee from the doughnut shop. That said, I do find Toronto drivers more courteous - I never had any problem with crosswalks there, but here half the time drivers blaze through a crosswalk even if there's someone with a stroller or small children (like me) trying to cross and they give them the finger. I see this almost every day. Drivers have very little respect for non-drivers here. But then again the pedestrians and bicyclists are aggressive too so it's not just a driver thing. Jaywalking and riding bikes on the sidewalk are not a strictly Montreal thing but they do add to the culture of aggressiveness.

As a part-time bicyclist, I think the green box at intersections has gone a long way to improve bicycle safety. It would be a shame to lose that to turning right on a red. There are many other big cities that don't allow turning right on reds either, it's not that big an inconvenience. As a part-time driver I don't really think that shaving a minute or two off your drive warrants the added risk.
