To be fair, HSR across the Rockies sounds extremely expensive and extremely inefficient.
I don't think we're going to be fixing Vancouver's isolation anytime soon.
Not just expensive, downright impossible. The Rockies are volcanic, so boring a level tunnel through the base of the mountains is out of the question. They're also very steep, which necessitates a lot of switchbacks, sharp curves, and even a pair of spiral tunnels at Kicking Horse Pass. We can and do run normal trains through these lines, but the geography severely limits how fast we can move through the terrain.
Don’t think the Rockies are volcanic. I can’t find any sources to support that.

There currently aren't any active volcanoes in the Canadian Rockies, but there is still magma towards the base of them that we'd run into if we tried to bore tunnels straight through. In theory, we could bore tunnels at a sharp incline to go over the magma; but that basically eliminates all the benefit vs just building rail lines on the surface like we already have, plus there's the added complexity of trying to make an earthquake-safe tunnel that crosses a fault line.
