I guess we don't need to rehash this discussion. Street running LRT is not rapid transit. Toronto needs a crosstown/orbital line to connect the various radial lines (subway/GO) Line 5 is a failure in that regard. Sheppard is our next opportunity but it seems likely we will screw it up by building it as $1b/km underground TR. Converting to LRT and street running is a failure in the other direction. Maybe our next hope is the 407 orbital line. It's just a disaster for regional transit connectivity that we do not prioritize a fast orbital connection. It's not sustainable for downtown to be the only easily accessible location for employment.
Sheppard could work but they would need to shut it down to convert it to Ontario Line tech. I don’t know how politically feasible that would be. A GO midtown line could also work but I don’t see it working. A 407 line using Ontario line tech running from Burlington to Oshawa could work.
