Even we are trying to move to Windsor this July. From whatever I've gathered by speaking to some folks in Windsor, the Canadian officials are calling up multiple times to ensure recent entrants/visitors are complying with the quarantine rule. Incase of any suspicions, they may even be visiting the given address in person. I guess this strict enforcing may be partly because the Govt. bears the primary responsibility of the nation's healthcare, on both the fiscal and operational side.
In terms of house showing, due to Covid-19 situations, most of the house showings, esp. through Agents, are being done through video calls. Atleast that has been my experience in the last month when I was searching for a rental property. Coming to banks, it seems you may be able to open bank accounts in Canada through online, without the need for a physical presence.
Lastly, even though you have lost 1.5 years, you still have 1.5 years left(given the req. to stay 2 out of 5 yrs). Hopefully, this should give you ample time on your hands to fulfill your settlement needs without taking undue risks/stress. Good Luck on your move!
