Airbnb and Short-Term Rental Taxes in Canada: What Ottawa Operators Need to Know
Running an Airbnb in Ottawa? CPA Majdi Ibrahim explains income tax, GST/HST, the deduction denial rule, and what non-compliant rentals really cost.
By Majdi Ibrahim, CPA | Majdi Ibrahim, CPA Professional Corporation | Ottawa, Ontario
Short-term rentals have become a meaningful source of income for thousands of Canadians — and an increasingly complex tax situation for many of them. Renting out a spare room, a basement suite, or a cottage through Airbnb or VRBO sounds straightforward. The tax side is anything but.
This article is for Ottawa-area landlords and property owners who are running, or thinking about running, a short-term rental. It covers the income tax rules, the GST/HST obligation that catches most operators off guard, the newer deduction denial rule for non-compliant rentals, and the Ottawa-specific licensing context that makes all of this locally relevant.
We cover the broader rental income picture in our rental income tax guide. This article focuses specifically on short-term rentals.
At a Glance
All short-term rental income is taxable. There's no threshold below which you don't have to report it.
Short-term rentals are generally taxable supplies for GST/HST purposes. Long-term residential rentals are usually exempt. Short-term is not. If you exceed the $30,000 small supplier threshold, GST/HST registration is required.
For taxation years after 2023, deductions can be denied for non-compliant short-term rentals. If your rental doesn't meet local licensing and permitting requirements, you may lose the ability to deduct expenses — even though the income is still taxable.
The definition of "short-term" differs by rule. For GST/HST, it's generally under one month. For the income tax deduction denial rule, it's under 90 consecutive days.
Ottawa has its own short-term rental licensing regime. Operating without a licence isn't just a municipal issue — it can now have direct income tax consequences.
Reporting Short-Term Rental Income
Short-term rental income is reported as income on your personal T1 tax return. Depending on the nature and scale of the activity, it may be reported as:
Rental income (T776 — Statement of Real Estate Rentals): This is the most common treatment for property owners renting on platforms like Airbnb. You report gross rental revenue and deduct allowable expenses. Net income (or loss) flows into your total personal income for the year.
Business income: If the services you provide go significantly beyond basic accommodation — regular cleaning, meals, concierge services, linen changes — CRA may treat the activity as a business rather than a rental. Business income is reported differently (on Form T2125) and has different rules for deductions and CCA. Most casual Airbnb operators don't cross this line, but operators running a more intensive hospitality-style operation might.
The distinction matters because rental activities have specific CCA restrictions, including that CCA generally cannot be used to create or increase a rental loss. Business income is reported differently, and the expense and loss analysis can differ depending on the facts. Basic occupancy services such as heat, hydro, parking, and ordinary turnover cleaning usually do not, by themselves, make the activity a business. More hotel-like services — meals, concierge services, tour booking, daily cleaning or linen changes during the stay — increase the business-income risk. If your operation is substantial or you're uncertain, it's worth getting a clear picture before filing rather than after.
Deductible Expenses for Short-Term Rentals
The general rule is the same as for long-term rentals: expenses incurred to earn rental income are deductible. For short-term rentals, this commonly includes:
- Mortgage interest on the property (not principal)
- Property taxes (proportionate to rental use if property is also personally used)
- Insurance (rental-use portion)
- Repairs and maintenance
- Platform fees (Airbnb service fees, VRBO listing fees)
- Cleaning costs
- Supplies (linens, toiletries, coffee — consumables provided to guests)
- Photography and listing costs
- Municipal licensing and permit fees (where the rental is compliant)
Personal-use proration matters. If you rent out a property you also use personally — a cottage, a room in your home, a condo you stay in occasionally — only the portion of expenses related to the rental-use period and rental-use space is deductible. A property rented 60% of the time and used personally 40% can only deduct 60% of shared expenses like insurance, mortgage interest, and property taxes.
Capital improvements are not immediately deductible — they're added to the Adjusted Cost Base (ACB) of the property. The repairs vs. capital improvements distinction applies to short-term rentals just as it does to long-term ones.
The Deduction Denial Rule: Non-Compliant Short-Term Rentals
This is the rule that changed everything for short-term rental operators, effective for taxation years after 2023.
What the rule says: Income tax deductions can be denied for expenses related to a non-compliant short-term rental property. For this purpose, a short-term rental is defined as a residential property rented or offered for rent for periods of less than 90 consecutive days.
What makes a rental non-compliant:
- Operating in a municipality or province that prohibits short-term rentals in that location (zoning restrictions, strata rules, condo bylaws)
- Not holding the required provincial or municipal registration, licence, or permit
The result: If your rental is non-compliant, you still report the income, but deductions related to the non-compliant short-term rental period can be denied. In a fully non-compliant operation, that may mean no deduction for expenses such as mortgage interest, property taxes, insurance, repairs, and platform fees against that income.
This is separate from GST/HST. The deduction denial rule is an income tax rule. GST/HST compliance is a separate obligation entirely (covered below). You can be compliant for GST/HST and still have deductions denied for income tax purposes if you're not licensed.
Ottawa's Short-Term Rental Licensing Rules
Ottawa introduced a short-term rental licensing regime that operators need to understand — not just for municipal compliance, but because non-compliance now has direct income tax consequences.
Under Ottawa's rules:
- Short-term rental operators (renting for less than 30 days) are generally required to register and obtain a licence from the City
- The property being rented must generally be the operator's principal residence, with additional rules depending on ownership, tenancy, condo or co-op restrictions, and the specific property
- Operators must display their licence number in all listings
The specific rules and zones matter. Before assuming your short-term rental is compliant, municipal eligibility should be confirmed with the City or an appropriate legal or licensing advisor. A CPA can then help assess how that compliance status affects the income tax deduction rules.
The practical implication for tax purposes: If you're operating a short-term rental in Ottawa without a licence, your deductions are at risk under the post-2023 rules, regardless of whether the city has taken enforcement action against you yet.
GST/HST: The Obligation Most Operators Don't Know About
This is one of the most common surprises in short-term rental taxation — and one of the most expensive to discover late.
Long-Term vs. Short-Term: The Key Distinction
Long-term residential rentals — generally accommodation provided continuously to the same person for one month or more — are typically exempt supplies for GST/HST purposes. No GST/HST is charged, and no Input Tax Credits (ITCs) are available on related expenses.
Short-term accommodation — generally under one month — is generally a taxable supply. GST/HST applies.
The $30,000 Registration Threshold
If your total taxable supplies, including short-term rental revenue, exceed $30,000 over four consecutive calendar quarters or in a single quarter, you are generally required to register for GST/HST. Once registered:
- You must charge and collect HST (13% in Ontario) on the rental revenue
- You must remit the HST collected to CRA, net of any Input Tax Credits
- You may claim ITCs on eligible expenses related to the taxable short-term rental activity (cleaning services, supplies, platform fees, etc.)
Many Airbnb operators underestimate how quickly they reach this threshold. A property renting for $150–200/night and generating $35,000–$50,000 in annual revenue is already over the threshold.
Airbnb and HST: What the Platform Does and Doesn't Do
Airbnb may collect and remit GST/HST on certain bookings where the host is not registered for GST/HST. However, if you are required to register, or if you provide your GST/HST number to the platform, you may be responsible for charging, collecting, and remitting GST/HST on the accommodation revenue. Do not assume the platform has handled your entire GST/HST obligation without reviewing your registration status and platform settings.
The GST/HST rules can also differ depending on whether you are registering under the regular GST/HST rules or the platform-based short-term accommodation rules. The practical point is the same: once short-term rental revenue approaches $30,000, the GST/HST status should be reviewed before assuming no registration is required.
Change-in-Use When Converting to Short-Term Rental
If you purchase a property as a long-term rental (exempt) and convert it to short-term (taxable), or vice versa, there can be GST/HST self-supply and change-in-use implications — including potential deemed supplies at fair market value. In some cases, a property used primarily in taxable short-term rental activity can also create GST/HST issues on a later sale. This is genuinely complex territory and worth a specific review if you're converting a property between uses.
Change-in-Use: When Taxes Trigger Without a Sale
One of the less intuitive aspects of short-term rental taxation is that changing how you use a property can trigger a capital gains event even without selling it.
If you convert a property from personal use to rental use — or from long-term to short-term rental — CRA's change-in-use rules may deem a disposition at fair market value at the time of conversion. This can create a capital gain even though no money changed hands.
The most common situations:
- A cottage used personally for years that is put on Airbnb
- A condo that shifts from long-term tenant to nightly short-term rental
- A principal residence where a room begins to be rented on a short-term basis
In some cases, a subsection 45(2) or 45(3) election may be available to defer the deemed disposition — but timing and CCA history matter. This is one of those decisions that's significantly easier to make before the conversion happens than after.
We cover the capital gains implications in more detail in our capital gains article.
What CRA Watches for With Short-Term Rentals
Under-reported income. Digital platform reporting rules have increased the amount of information available to tax authorities. Short-term rental operators should assume platform income is visible or can become visible to CRA. Assuming rental income won't be noticed is a significant risk.
Unregistered GST/HST. Operators over the $30,000 threshold who haven't registered are a compliance priority. Operators over the threshold who failed to register may face retroactive registration, unremitted tax, interest, and potential penalties.
Non-compliant deductions post-2023. The deduction denial rule gives CRA a clear hook to disallow expenses where municipal licensing compliance can't be demonstrated.
Inflated expense claims. Personal-use properties where 100% of expenses are being deducted against short-term rental income — without proper proration — are a common audit issue.
The best defence is good records. A clear log of rental nights vs. personal-use nights, receipts for all expenses claimed, documentation of municipal licence compliance, and proper HST account records make a significant difference if CRA reviews your returns.
Ottawa & Area: Local Context
Ottawa licensing: As noted above, Ottawa requires short-term rental operators to hold a city licence, generally limited to principal residences. An operator running a non-principal-residence short-term rental in Ottawa is exposed both municipally and under the post-2023 income tax deduction denial rules.
Gatineau operators: Quebec has its own provincial short-term rental rules, separate from Ontario's and Ottawa's regime. Quebec operators face Quebec-specific registration requirements. If you live in Ottawa but operate a short-term rental in Gatineau, both jurisdictions' rules may be relevant.
Student area properties. Short-term rentals near uOttawa, Carleton, or Algonquin during peak periods — convocation, orientation, major events — are common. These are still subject to Ottawa's licensing rules and all the income tax and GST/HST obligations above.
What Happens When You Bring This to Majdi Ibrahim, CPA?
A clear compliance picture. We review your specific situation — the property, the rental pattern, the municipal status, the revenue — and tell you exactly where you stand on income tax reporting, GST/HST registration, and the deduction denial rules.
GST/HST registration and catch-up if needed. If you've been operating over the threshold without registering, we help assess the exposure and the options — including whether a voluntary approach to CRA makes sense before they contact you.
Proper proration of personal and rental expenses. If the property has mixed use, we make sure the deductible portion is calculated correctly — defensible, not aggressive.
Year-end planning for short-term rental operators. Timing of capital purchases, CCA decisions, and the income vs. business income question are all worth reviewing before year-end, not after.

Frequently Asked Questions
Do I have to report Airbnb income?
Yes. All short-term rental income is taxable in Canada and must be reported on your T1 tax return. There is no minimum threshold for income tax reporting purposes. Digital platform reporting rules have increased the amount of information available to tax authorities, and short-term rental operators should assume platform income is visible or can become visible to CRA.
Do I need to charge GST/HST on my Airbnb rental?
If your total taxable revenues — including short-term rental income — exceed $30,000 over four consecutive calendar quarters or in a single quarter, you are required to register for GST/HST and charge HST (13% in Ontario) on your short-term rental revenue. Many operators reach this threshold without realizing it. Long-term residential rentals (generally one month or more) are typically exempt from GST/HST. If you are required to register, or if you provide your GST/HST number to the platform, you may be responsible for charging, collecting, and remitting on the accommodation revenue. Airbnb may collect tax in some cases where the host is not registered, but registered hosts should not assume the platform has handled the full obligation.
What happens if my short-term rental is not licensed in Ottawa?
For taxation years after 2023, operating a non-compliant short-term rental — including one that doesn't hold the required municipal licence — can result in deductions related to the non-compliant rental period being denied. You still report the income, but expenses cannot be offset against it. Municipal eligibility should be confirmed with the City or an appropriate legal or licensing advisor. A CPA can then help assess how that compliance status affects the income tax deduction rules.
Can I deduct my mortgage on a short-term rental?
You can deduct the interest portion of the mortgage — not the principal repayment. If the property is also personally used, only the rental-use portion of the interest is deductible. Getting the proration right matters, and your lender's annual interest summary is the right starting point for the calculation.
Is short-term rental income business income or rental income?
For most casual Airbnb operators, it's rental income reported on Form T776. If you're providing significant services beyond basic accommodation — daily cleaning, meals, concierge — CRA may treat it as business income on Form T2125. The distinction affects reporting, CCA treatment, and how losses are reviewed. Most operators don't cross the business income line, but the question is worth reviewing if your operation is more intensive.
What are the tax consequences of converting my cottage to a short-term rental?
Converting a personal-use property to a rental can trigger a deemed disposition under CRA's change-in-use rules — a capital gains event even without a sale. A subsection 45(2) election may be available to defer the deemed disposition, but timing and CCA history matter. This is one of the decisions that's much easier to navigate before the conversion than after.
I've been renting on Airbnb for a few years without registering for GST/HST. What should I do?
If you've been over the $30,000 threshold without registering, you may face retroactive registration, unremitted tax, interest, and potential penalties. The sooner this is addressed, the better — the options available narrow as time passes. Speaking to a CPA before contacting CRA yourself is strongly advisable.
