I'll add a minor point: with the rising bicycle use in Québec we're seeing a new issue pop up, where a good few cyclists mistakenly treat walk signs as green lights, endangering pedestrians (and other cyclists) with the speed at which they enter the crossing, or wrongly expecting pedestrians to yield to a bicycle instead of the other way around.

Toronto need to make sure the TPS is trained in up to date cyclist & pedestrian safety for this to work. In the last two years I've had the pleasure of seeing SPVQ officers reminding cyclists to yield to pedestrians when they signal crossings, and it makes a noticeable difference over time.
