I drove from Toronto to Buffalo to void the required test. Once you leave the country it is no longer required as you can no longer spread any virus to Canadians and you cannot feasibly take the test anywhere. I got gas in USA (with a time stamped receipt) and re-entered on a new arrivecan. There are no random tests for land entries. From now on I will always put in my arrivecan that I am entering either by land or at YTZ to avoid being randomly selected. I’ll just say my original flight to BUF/YTZ got cancelled and the airline flew me instead to YYZ.
