Hello Sadie
You may like to contact your local Tax Dept to establish any legal obligations.
Alternatively you may like to look up posts in here by your fellow countrymen & women using keywords like Canada etc.
I hope you have included your own hourly worth in your pricing, and ignore the pricing suggestions they pop under our noses to lower them if its quiet...
You may also like to ensure you include a reference to Instant Bookings and pre approvals because if you have IB on you may get lots of IB including by those who want to stay longer term that are better to be more closely verified for compatibility etc.
Feel free to look at my listing re IB.
It pays to err on the side of caution as there's good and bad people everywhere.
All the best.
