I'm following the advice of a moderator on the Facebook page Thailand Visa Advice and not this group. An added hurdle is flying out of Canada to Thailand with a longer flight itinerary than your visa, airlines often turn people away. If you have a visa you obtained with the flight itinerary, then you have a good chance of convincing them to let you go. I've experience this and know of others who have too. So it's a little bigger than just covid extensions.
