Today - July 5, 2021, fully vaccinated travelers (which I have been for a month) can come back into Canada without the hotel quarantine but beware
1. you had to have had the full vaccine (two doses at least 14 days before travelling/coming home)
2. the international borders are still closed to "non-essential travel". That means no vacation travel .abroad
3 You still need the dreaded PCR test before coming in and then once you come in - lots of extra effort and costs
4. You have to sign up for ArriveCan app to provide all of you vaccine and travel info
Use ArriveCAN: Submit travel information to enter Canada - Canada.ca
4. I still figuring out the best ways to get the PCR tests both here and abroad for my travels. I will share when I know more
Hope this helps
