Short-term rentals look like an easy way to boost a property's income. List it on Airbnb, charge nightly rates instead of monthly rent, and the math often looks better than a long-term tenant. The financing side is where that math gets more complicated, and it works differently in Canada than a lot of what you'll find searching online, which is written for the American market.
Here's what actually applies if you're financing a short-term rental in Ontario.
The rule that changes everything: check where you can legally operate first
Before any conversation about mortgages, there's a more basic question. Can you legally run a short-term rental at this address at all?
Toronto only permits short-term rentals in a person's principal residence, the home where they actually live, sleep, and get their mail. Investment properties, second homes, and units you don't personally live in cannot be listed for stays under 28 days, full stop. Ottawa has a similar rule, with some added flexibility for renting rooms. This means the classic "buy an investment property and Airbnb it" strategy, common across a lot of financing content aimed at American investors, simply isn't legal in Toronto or Ottawa for anything other than the home you actually live in.
Other parts of Ontario are more permissive. Niagara Falls and Niagara-on-the-Lake, for example, don't require the property to be a principal residence, which is part of why cottage country and tourist towns remain popular for dedicated STR investment. Rules vary meaningfully by municipality, and they change. Always confirm current bylaws with the specific city or town before assuming a property qualifies, and if it's a condo, check the condo corporation's own declaration and rules too. A condo board can prohibit short-term rentals even where the city allows them, and that ban overrides the city's approval.
This matters for financing because it changes what you're actually asking a lender to finance: a mortgage on your own home where you'll rent out a room or two, versus a mortgage on a separate investment property. Those are different conversations.
How Canadian lenders actually treat short-term rental income
If you've searched this topic, you've probably run into a lot of content about DSCR loans, a US mortgage product that qualifies you based purely on a property's rental income. That product doesn't really exist in Canada in the same form. Here's what does.
Most big banks default to long-term rental rates, but this isn't an absolute rule. The major Canadian banks and most large credit unions will typically qualify a property based on its long-term rental market rate rather than what it could earn as an Airbnb. If a two-bedroom condo would rent for $2,200 a month on a standard lease, that's often the number they'll default to, even if you're planning to run it as a $4,500-a-month Airbnb. That said, some big banks will consider actual short-term rental income directly on a deal, particularly where there's a proven operating history on the property or on comparable properties. This tends to be handled case by case rather than as an advertised program, which is exactly the kind of detail worth asking us about directly before you assume the answer either way.
B-lenders and some credit unions are more flexible as a rule, and a number will consider actual or projected short-term rental income directly, particularly local credit unions in cottage or tourism-heavy regions who understand that market. Expect a rate roughly 1 to 2% higher than a big bank would offer, along with additional fees, in exchange for that flexibility.
Documentation matters more than people expect. If you're already running a short-term rental and want that income to help you qualify for your next property, lenders will want to see it properly reported. This is one of the more common mistakes: hosts who run an Airbnb, collect the income, and don't report it on their taxes. When it comes time to use that income history for a future mortgage, there's nothing to show a lender. Reporting the income, and paying tax on it, is what makes it usable later.
Rental income generally can't be used twice. Under current federal banking guidelines, income you've already used to qualify for one mortgage generally can't be reused to qualify for a second one. This mostly affects investors scaling up a portfolio rather than someone buying their first property, but it's worth knowing if short-term rental income is part of a bigger growth plan.
The realistic financing paths
If it's your principal residence with a legal secondary suite, basement unit, or laneway suite: This is the most straightforward path in Toronto and Ottawa, since it fits within the principal-residence rule and is a scenario most Canadian lenders are comfortable with. A standard residential mortgage applies, and many lenders will let you use anywhere from 50% to 100% of the secondary unit's income to help you qualify, though this is usually based on projected long-term rental value rather than short-term rates. Whether you actually run that secondary unit as a short-term rental afterward is a separate operational decision from how the mortgage was underwritten.
If it's a dedicated investment property in a municipality that allows it: Expect standard investment property mortgage terms: typically 20 to 35% down. Qualification is often based on long-term market rent rather than projected Airbnb income, though some big banks will underwrite actual short-term rental income directly if there's a solid operating history to point to, and B-lenders and credit unions tend to be more consistently open to it. Either way, build your fallback numbers around the conservative, long-term rental figure. If the property only cash-flows as a short-term rental and would lose money as a regular tenancy, that's a real risk, not just a financing inconvenience. Regulations can change, platforms can delist a listing, and a bad season can happen. A property that only works one way has no fallback.
If you're tapping equity from an existing property: A home equity line of credit (HELOC) or a cash-out refinance on a property you already own is a common way to fund the down payment on a short-term rental purchase, since it's secured against real estate you already hold rather than counted as unsecured borrowed funds. Lenders can see the difference, and many won't accept a down payment that came from an unsecured personal line of credit.
What to have ready before we start
- Confirmation the property can legally operate as a short-term rental, in writing where possible: municipal bylaw, zoning, and condo declaration if applicable.
- A long-term market rent estimate for the property, since that's the number most lenders will actually use, even if short-term income is your real plan.
- Two years of tax returns if you're already running any rental income, short or long-term, since lenders will want to see it reported.
- Bank statements showing rental deposits, if you have an operating history.
- A realistic budget that includes mortgage payment, property tax, insurance, higher short-term-rental-specific insurance if applicable, cleaning and management costs, municipal registration and accommodation tax obligations, and a vacancy buffer, not just the mortgage payment against gross projected income.
Bring us whatever you've got on this list, even if it's incomplete, and we'll help fill in the rest before deciding which lender to approach.
The honest bottom line
Short-term rental income can genuinely make a property more profitable to operate. It rarely helps you finance the property in the first place, at least not through a major Canadian bank as a matter of course. The financing conversation and the operating plan are two different things, and treating them as one is where a lot of hopeful investors run into trouble. Confirm the property can legally be used the way you intend, qualify the mortgage on numbers a lender will actually accept, and let the short-term rental upside be the reward for running the property well, not the assumption the whole purchase rests on.
If you're weighing a short-term rental purchase, or trying to figure out whether a property you already own could qualify for the right kind of financing, this is exactly the sort of file we like sorting through with clients before an offer goes in, not after. Reach out and we'll walk through the numbers with you.
