The STV program has been extended until September 2022. What they didn't do is update the requirements, like quarantine length, testing, etc. The Vancouver consulate is encouraged to believe that the November statement/press release will bring clarity to the situation.
I'm still waiting for a reasonable air route. Singapore air will be flying to and from Vancouver BC starting December 2. I plan on being on a flight that week if I can find out what the freaking requirements of the STV are.
