The claim that a subway would be needed to handle the load should be the last thing to be considered, at least along that alignment.
This is central King St in TO and San Diego's central LRT corridor + transit mall (E-W along the centre of the image), both shown at the same elevation. There's very clearly a stark difference. If we're to go global and choose any other city with a central transit mall, I believe it's safe to say there'd be a stark difference with King as well. Not saying we shouldn't have a transit mall, but it's very clear that a grade-separated transit solution is needed through the core. Toronto planners deduced this a century ago, and numerous times since then. This isn't the boonies, this isn't the 905, this isn't the former boroughs, nor is this a quaint old style downtown... It's the centre of the 4th largest city on the continent and a leading global financial hub. The current and proposed densities blow San Diego and numerous other surface streetcar/LRT cities out of the water many times over.
If we are silly enough to not build a new E-W subway across the core, then any streetcar/LRT solution must be grade separated through the core. Nothing else will work. And not in the plannertician sense that gets suburban subways built, I mean literally. Again, this was deduced many times since the early half of the 20th C.
