New Airbnb Hosts in Canada Must Register Before They Deduct Expenses

Anyone drawing up a launch plan for a Canadian Airbnb in 2026 needs a municipal license or provincial registration number before writing off a single expense. Since January 1, 2024, Ottawa has denied income tax deductions on short-term rental income earned in any province or municipality where the operator isn't compliant with local licensing rules, or where short-term rentals are banned outright. That federal measure now sits ahead of platform sign-up on the actual to-do list for new hosts.

The federal rule that changes the math

The deduction denial applies whether or not a host ever gets caught by a city inspector. If a municipality requires registration and the host doesn't have it, the Canada Revenue Agency treats mortgage interest, cleaning, utilities and platform commissions as non-deductible against that rental income. A host renting a Toronto condo without the city's short-term rental registration number can still take bookings on Airbnb, but the tax return lands as though none of the operating costs existed.

Licensing still runs city by city

Toronto limits short-term rentals to a host's principal residence and requires city registration before a listing can go live. Vancouver enforces a similar principal-residence rule tied to a business license. Quebec goes further: every short-term rental needs a registration number from the province's tourism regulator, and Airbnb has required Quebec hosts to display that number on the listing itself since the rule took effect. None of these systems talk to each other, so an operator with properties in more than one province files separate paperwork on separate timelines for each.

The tax threshold hosts tend to miss

GST/HST registration is the other line item that trips up first-time hosts. Any operator whose worldwide taxable rental revenue clears CAD 30,000 across four consecutive calendar quarters must register for GST/HST and begin charging it, a threshold a single well-booked property in a market like Banff or Whistler can clear within one peak season. Getting that registration in place before the threshold hits, rather than after, avoids a retroactive bill on bookings already taken.

None of this changes what a Canadian short-term rental can earn. It changes the order of operations: registration and licensing now come before the spreadsheet of projected income, not after the first guest checks out.
