Finch is 40m wide in some places and all of that space is either track or car lanes, whereas in that video, Paris provides loads of space for pedestrians to cross in stages if they need, either a couple metres wide or huge areas, breaking up crossings by creating refuge islands, often protected by bollards. At every pedestrian crossing in that video there is enough room for a people to cross part of the way and safely wait if there isn't enough time to cross fully. If we had that here maybe different timings could be considered.
Toronto uses
1.0 metres / second as a walking speed to account for those walking slower, like children or seniors. Shortening pedestrian crossing times would mean people would get "trapped" in the middle, and creating refuge islands would be an incredible cost (worth it everywhere imo, but that's not happening).
I once asked Becky Katz, who used to head the pedestrian unit in transportation services, why the city doesn't have two/multi stage crossings, and her answer was people
hate them, and that creates an obstacle at the city. It stunned me because when I've used them in Europe I think they're amazing and feel much safer, but they're often configured to have people only cross one or two lanes at a time. The one people here know is at Queen and University where you're crossing 4 lanes on each side of the refuge, so I guess it's not surprising that when that's your image of a two/multi stage crossing, you dislike it.
