At this point, I think only big healthy street trees can help with making these streets walkable. Along with reducing lanes, narrowing lanes, reducing speeds adding green medians. I don't think the buildings will frame the road well enough. They are still building new buildings with strange green strips of grass between them and the sidewalk. Not park or amenity space, just weird unnecessary setbacks. It would be better if they were plantings with benches etc.
I can see eventually adding a loop on HuLRT around Square 1 as originally proposed. Not sure there is enough along Burnhamthorpe to support LRT to Islington. And LRT is not great value for money given how slow it is. Perhaps a BRT could be justified eventually, but it would probably be sapped of demand between the Dundas BRT to the south and Transitway along the 403. Really, Dundas BRT could have a branch off that goes up to MCC and connects with Kipling. It would make more sense to hook MCC into GO where you have a hope of getting somewhere inside an hour.
