It doesn’t matter if you are vaccinated, you still need to do the mandatory 3 day hotel quarantine (you pay) and then an 11 day home quaratine. There are no exceptions. Please don’t post in CAPS, it means yelling.
Currently you still have to quarantine. Assume that will eventually change so monitor the Canadian government website and it may also depend on the proof required because unfortunately people will falsify proof of vaccinationl
