I haven't seen much in Montreal - and offhand, I don't recall any on R-L, or Dorchester - though it's not impossible they've added a few feet here and there. Though there's lots of flower boxes in a few spots. R-L however is a 6-lane arterial, with a median. It's more akin to University than King. St. Catherines would be a better comparison to King, and I recall no fencing there.
Gosh, that's ugly. But how is this comparable? It's a 7-lane artery, out in the suburbs, adjacent to a large bus terminal at the terminus of a subway line. The fence runs for all of 70 metres, along the south side of the terminus. I suspect the problem you get here, is that a lot of students for nearby Vanier Cegep, and Cegep de St-Laurent arrive on bus, and then make a beeline across the road. This is similar to the 65 metres of fencing we see in Toronto on Bay Street from Front to the train tracks, outside the GO bus terminal.
Vanier is my Alma Mater, though before they build that Metro station. Dawson too in pre-motherhouse days. However, it's no secret I'm playing without a full DEC.
I said earlier, that a short piece of fence near an intersection wasn't a big issue. Nor have I complained about the Bay fence (though I think there should be a pedestrian crossing of some kind at the south end of that), similar to the new one on Yonge) - perhaps there's be a chance to do that with the end comping to the GO terminal.
Though I honestly don't know which spot on King actually needs that, being a much narrower road. Perhaps near St. Andrew - though University is a more likely candidate really. It's much wider, and doesn't have the small stores on each side; it's much more like Dorchester.
Often it's sheer stupidity that has lead to them - and a surprising number hit by the streetcar they just got off. Many are at intersections, where the fence wouldn't apply.
That's just a a stop though. I wasn't precluding ANY barrier. In particular I was objecting to mid-block barriers and at intersections that had no signals (like Victoria/King). You don't have stops at those locations.
