We crossed back into Canada April 1st, the 1st day pre-arrival covid tests were not required.
I was "randomly selected" and told to complete the take home test from @SwitchHealthCA within 24 hours. /1
Within an hour of getting to our cottage, fairly remotely located, where we indicated we would isolate in our #ArriveCan app (which worked well) as part of the quarantine plan ArriveCan asks for, I started the registration and testing process. /2
