> the U.S. immigration situation is helping the Canadian tech scene

Well, India and China have even fewer immigration restrictions on Indian and Chinese workers than Canada does... why would Vancouver take San Francisco’s place rather than Mumbai or Shanghai?

Shanghai is practically topped-out already, there's a huge amount of VC funding being spent and it's quite hard to emigrate there. Though I don't think it's about US policy so much as just good success at reproducing the Hong Kong business environment.
