It worked extremely well for the Chinese. A bunch of motivated premature analysis kept insisting it was a failure pre mass adoption - HSR takes decades to reach full utilization - now few years later it's hitting positive net returns when considering society wide multiplier effects. Also bonus of developing secondary cities along routes, which is actually perfect for Quebec-Windsor corridor that contains half Canadian population along 1200km line. It's almost a no brainer if Canada wants to keep immigration flowing and decongest new comers settling in a few cities. Extra bonus it's electrified, Canada can build trains, and it's more comfy than aviation. Primary problem is Canada/US can't build large scale infra anymore, especially not proper HSR that needs to be elevated, more so to have it route/link to networks that connect urban centres.
