I left 14 months ago after being told the same thing, I was sitting in the airport at the gate when a friend sent me a link telling me they would change the rules 24hours and 5 minutes after I left...
You can get a test done outside if you have been travelling in provinces with high corona or if you have been in contact with someone who has tested positive.
it was, or at least it was today but rules change all the time. I wasn't aware of it till i stood there but I managed to talk my way into a free test :p
I'm at immigration now and came on the same 2 month multiple tourist visa, I will tell you if I get my one month extension in 30 minutes or so once they come back from lunch
