Hey there, also Canadian traveler out of Ontario. I have been to St Maarten twice in the last 2 months for a few weeks at a time. The rules change and as of January 1st they change again for entry to sxm. Toronto Pearson Terminal 3 was no big deal a couple of weeks ago. Keep printed records of your qr-code vaccine info from Ontario. Also your qr-code from EHAS which you will be able to do within 72 hours of your departure. They will also prompt you to buy covid insurance for $15. You will get a copy of that when you get your ehas q r code pre-entry approval. I am surprised that you are flying Air Transat which is generally a Sunday flight. My flight was supposed to be Air Transit on
January 23rd and was cancelled a week ago. I am now flying down on the 20th of January. I have a residence in Maho so I am there frequently over the winter. If you have any specific questions I could try to answer or there are many on this forum who have lots of knowledge. Try not to worry.
