How cottage mortgages work in Ontario

Yes, you can get a mortgage on a cottage

Yes. Cottages get financed every week in Ontario, and most of the families considering a cottage are surprised by how normal the process feels. The paperwork is much the same as for a city home mortgage. The property is what changes. A lender is lending against a building on a lake, often on a private road or heated by a wood stove, and once in a while reachable only by boat. How that building is set up decides your down payment, your rate and which lenders will even look at it.

This guide walks through how cottage mortgages really work, from how lenders sort properties to how you qualify while still carrying your home. If you want a number first, try the cottage mortgage calculator or how much cottage you can afford, then come back for the why.

Boat access does not automatically rule out mortgage insurance. Sagen’s Type B programme permits boat-only access for eligible personally occupied properties, with up to 90% financing and an own-resources down payment. Canada Guaranty excludes islands without bridge access. A lender must still accept the exact access, title, condition and marketability; insurer eligibility is not a mortgage approval.

How a cottage mortgage differs from a home mortgage

On the surface it is the same product: a term, a rate, an amortization and a monthly payment. Underneath, four things change.

• The property is judged harder. Lenders look at road access, a permanent heat source, the foundation, the water supply, the septic system and how easy the place would be to resell. A city house rarely fails any of these. A cottage often fails one.
• Fewer insurers play. CMHC stopped insuring second homes on May 30, 2014. Today only Sagen and Canada Guaranty insure cottages, and their rules are narrower than for a principal home.
• You are carrying two properties. Your existing mortgage, property tax and heating costs stay in your debt ratios, so your income has to stretch further.
• The lender pool shrinks for unusual places. Water access, island, leased land and off-grid cottages often push you toward credit unions or private lenders, with bigger down payments.

Year-round vs seasonal: how lenders sort cottages

Lenders and insurers split cottages into two broad groups. You will hear them called Type A and Type B. In plain terms, the question is: can you drive to it and live in it all winter?

The grey areas are where deals get stuck: a cottage on piers, a lake water intake instead of a well, a private road with a snow-ploughing agreement, or a wood stove as the only heat. We cover those in Type A vs Type B cottages and four-season vs seasonal cottages. The short version: check the property against lender rules before you firm up an offer, not after.

Insured second-home programs vs conventional mortgages

There are two paths to a cottage mortgage. Which one you take depends mostly on how much you put down and what the property is.

Insured (less than 20% down)

If you put down less than 20%, the mortgage must carry default insurance, and for a cottage that means Sagen or Canada Guaranty. Both run second-home programs with similar rules for year-round properties:

• Maximum 95% loan to value on a purchase, so 5% down on the first $500,000 and 10% on the portion above that.
• Purchase price strictly below $1,500,000 when you put down less than 20%, following the federal change on December 15, 2024.
• One unit only, used by you or an immediate family member. No rental pools, timeshares or condo hotels.
• Qualifying rate of the greater of your contract rate plus 2% or 5.25%.

Canada Guaranty requires a winterized home with year-round access and does not insure island properties without bridge access. Sagen's seasonal option (Type B) accepts cottages that are not winterized, with at least 10% down coming from your own resources. Sagen also limits applicants to one Sagen-insured vacation property. Rules vary by insurer, so the exact cottage matters.

Conventional (20% or more down)

Qualifying for a cottage when you already own a home

This is the part most online calculators skip, and it is usually the real limit. A lender adds up the costs of both properties and compares them to your income.

• Housing costs on the cottage: the new mortgage payment at the qualifying rate, property tax and heat.
• Your existing home: your current mortgage payment, property tax, heat and any condo fees.
• Other debts: car loans, lines of credit, student loans and credit card minimums.
• The stress test: you qualify at the greater of your contract rate plus 2% or 5.25%, for insured and uninsured mortgages alike.

Canada Guaranty publishes maximum debt ratios of 39% of gross income for housing costs and 44% for all debts on its second-home product. Lenders on conventional files set their own limits, and since 2025 federally regulated lenders also manage how many of their new uninsured loans go above 4.5 times the borrower's income. That cap applies across the lender's whole book of loans. It can still affect how flexible a lender feels on a big file.

The practical move: run your numbers with the cottage affordability calculator, which asks about your current home, then get a cottage pre-approval before you shop seriously.

Cottage mortgage rates

Cottage rates follow the same market as home rates, but the property and the structure of the deal can add a premium. Insured mortgages on clean year-round cottages are often priced close to regular home rates. Seasonal cottages, water access properties and anything that pushes you to a credit union or alternative lender usually costs more. We never publish a lender's rate as an offer because it changes daily and depends on the property. Our cottage mortgage rates guide explains what moves your rate and how to get the best one.

Amortization on a cottage mortgage

An eligible first-time buyer or purchaser of a newly built home may qualify for a 30-year insured amortization. Sagen adds 0.20 percentage points to its insurance premium rate for amortizations over 25 years. A repeat buyer purchasing a resale second home should model 25 years unless a different eligible structure is confirmed.

With 20% or more down, amortization becomes lender policy. Some lenders allow longer amortizations on conventional cottage mortgages, which lowers the payment and helps your ratios. Longer means more interest over time, so we usually show both options side by side.

Where your down payment can come from

Most cottage buyers fund the down payment from one or a mix of these sources:

1. Savings and investments. Cash, non-registered investments or a TFSA.
2. Equity in your home. A HELOC or refinance on your house. Federally regulated lenders cap the revolving line at 65% of your home's value and total borrowing at 80%. See using your HELOC to buy a cottage and the home equity calculator.
3. RRSP withdrawals. Allowed as a regular, taxable withdrawal. The tax-free Home Buyers' Plan and the FHSA are not available for a vacation property. Our FHSA and RRSP guide explains the one exception.
4. Sale proceeds. From another property or investment.
5. Gifts from family. Often accepted on year-round cottages. Seasonal insured cottages need the down payment from your own resources, so gifts and borrowed money need a careful look.

Do not forget closing costs on top. Ontario land transfer tax on a $650,000 cottage is $9,475, and the first-time buyer refund does not apply to a second property. The closing costs calculator adds it all up.

Properties lenders avoid

Some cottages are harder to finance. Expect fewer lenders and more money down.

• An eligible personally occupied boat-access cottage may fit Sagen’s Type B programme with 10% down from your own resources. The lender must also accept the property. Other financing structures may require more equity; there is no universal boat-access minimum.
• Crown land or leased land. You do not own the land, so options narrow to some credit unions or cash. See Crown land lease cottages.
• No potable water or a failing septic. Lenders may require a water test and hold back funds until treatment is installed. See wells, septic and water tests.
• Rental pools, timeshares, fractional ownership and condo hotels. Excluded by the insurers and generally declined by big banks.
• Cottages needing major work. See buying a cottage that needs work.

Big banks vs credit unions vs private lenders

As brokers, we place cottage files with all of these. The right fit often depends on one or two property details, which is why we ask about the cottage before we talk rate.

What to have ready

• Income documents: recent pay stubs and an employment letter, or two years of tax returns and Notices of Assessment if you are self-employed. See self-employed cottage mortgages.
• Your current mortgage statement, property tax bill and any HELOC balances.
• Proof of down payment, with 90 days of history in most cases.
• The listing, including heat source, water, septic, road access and any rental history.
• An idea of how you will use it: just family, or some rental. That changes the mortgage. See second home vs investment property.

Our take

Most cottage files that stall do so over the property, so that is where we start. Once the property type is clear and both homes are counted honestly, the rest of the mortgage is routine. When you are ready, start here and we will map the options for the actual cottage you are looking at.
