Update: We managed to fly to Toronto and everything went smooth, my friend got us an Uber to pick the car rental. We didn't get inside rental office, they did everything outside with social distancing and we got the car. Friend already bought us food for the trip and we drove straight to our quarantine place, with only a stop for gas. I dropped the car at the car rental, also they do everything outside and gave me a shuttle back home, I sit at the back and there is a shield to separate driver and me. Our quarantine will end in a few days.
