Hope you may have managed to get some information about this Tax topic. I also wanted to share this article which mentions ''The City of Toronto imposes a four (4) percent Municipal Accommodation Tax (MAT) for stays of 28 nights or less. Airbnb will collect and remit the MAT beginning January 1, 2021, and will provide more information to hosts when this process is available. For more information about the MAT, visit the City's Short-Term Rentals page.''
I am also reaching out to our fellow member from Toronto @Erlich2 if he can share some insights with you.
