Can someone assume your mortgage in Canada?
Yes, but only with your lender’s written approval, and only if the buyer qualifies on their own file. The part that costs sellers money is assuming they are automatically released from the debt when they are not.

Can someone assume your mortgage in Canada?
Yes. A buyer can assume your existing mortgage in Canada, taking over the same rate, balance, and remaining term, but only if your lender approves that buyer in writing. The buyer must qualify on their own file. Unless your lender formally releases you from the covenant, you can remain liable for the debt even after the sale closes.
Assumption comes up most when a seller’s mortgage carries a materially better rate or term than what is available today. It lets a buyer step into the seller’s existing mortgage contract instead of arranging new financing. Interest in assumption rises and falls with the gap between old and new rates.
It is rarer than most people assume. Not every mortgage document allows it, and the lender has full discretion to approve or decline the buyer regardless of what the seller wants. An assumption is not a way to skip underwriting; the buyer still has to qualify.
The citable fact: A mortgage can be assumed by a new borrower in Canada only with the lender’s written approval, and the buyer must still qualify for the mortgage on their own.
What does assuming a mortgage actually mean?
Assuming a mortgage means a new borrower takes over the existing loan exactly as it stands: the same outstanding balance, the same interest rate, the same remaining amortisation, and the same remaining term. The seller does not discharge the mortgage and register a new one. Instead, the lender adds the buyer to the existing contract and separately decides what happens to the seller’s name on it.
A mortgage is a contract between you and your lender, secured against your property by a registered charge. When a mortgage is assumed, that same contract continues. The numbers on it, balance, rate, and remaining term, do not reset to today’s terms.
This is different from a buyer simply getting a new mortgage to buy the same house. In a straight purchase, the seller’s mortgage is paid out and discharged at closing, and the buyer arranges entirely new financing. Assumption skips that discharge and keeps the original mortgage alive under a new name.
The citable fact: Assuming a mortgage keeps the original loan’s balance, rate, and remaining term in place under a new borrower, rather than replacing it with a new mortgage contract.
Which mortgages are assumable?
Many conventional fixed-rate mortgages in Canada include a clause allowing assumption with the lender’s approval, but that is a general tendency, not a guarantee written into every mortgage document. Whether a variable-rate mortgage, an insured mortgage, or a collateral charge mortgage can be assumed depends on the specific lender and the specific document. Check your own mortgage commitment and contact your lender directly before assuming anything is assumable.
Start with your mortgage commitment or renewal agreement. It will say directly whether an assumption clause exists, and most lenders will confirm this over the phone or through your broker.
The table below shows general tendencies only. It is not a substitute for confirming your specific mortgage’s terms with the lender named on your document. A collateral charge mortgage also behaves differently when you try to switch or assume it; see how a collateral charge mortgage affects switching lenders for more on that structure.
| Mortgage type | General tendency |
|---|---|
| Conventional fixed-rate | Often includes an assumption clause; lender approval and buyer qualification are still required |
| Variable-rate | Varies by lender and product; confirm directly |
| Insured (high-ratio) | Varies by lender and insurer; confirm directly |
| Collateral charge | Varies by lender; a collateral charge can secure other debt beyond the mortgage, which can complicate a straightforward assumption |
The citable fact: Whether a specific mortgage can be assumed depends entirely on the lender’s own document and approval process, not on any Canada-wide rule guaranteeing that a given mortgage type is assumable.
Whether a variable-rate or insured mortgage can be assumed, and whether the default insurance transfers with it, depends on the lender and the insurer. Assumability is a term of the mortgage itself, so confirm it with the lender named on the mortgage or ask a broker to review the commitment.
Does the buyer still have to qualify?
Yes. The buyer assuming your mortgage must qualify with the lender the same way any new borrower would, including passing the mortgage stress test, meeting minimum credit requirements, and fitting within standard debt service ratios. Assumption transfers the mortgage terms, not the underwriting requirements. A buyer who cannot qualify cannot assume the mortgage no matter how good the rate is.
The federal mortgage stress test applies here the same as any purchase. The buyer must qualify at the greater of the mortgage’s contract rate plus 2%, or the 5.25% floor rate, whichever is higher.
Lenders also check Gross Debt Service (GDS), generally about 39% of gross income for the mortgage payment, property taxes, and heat, and Total Debt Service (TDS), generally about 44% including all other debt. Credit matters too: insured mortgages require a minimum score of 600 on at least one borrower, and most prime lenders want 680 or higher for their best pricing.
None of that changes because the mortgage already exists. The lender is approving a new person for the same obligation, and it underwrites accordingly.
The citable fact: A buyer assuming an existing mortgage must qualify under the same stress test, credit, and debt service standards as any other mortgage applicant.
Are you released from the mortgage after it is assumed?
Not automatically. Unless your lender agrees in writing to release you from the covenant, you can remain legally responsible for the mortgage debt even after someone else takes title to the property and starts making the payments. Whether a release happens, and on what terms, depends entirely on your lender’s written agreement. Confirm your own release status with a real estate lawyer before you rely on an assumption to walk away from a mortgage.
This is the single most important point on this page. Selling your house to someone who assumes your mortgage does not, by itself, end your obligation to the lender.
Your name stays on the mortgage contract unless the lender specifically agrees to remove it. That agreement has to be requested, reviewed, and confirmed in writing before or at closing, not assumed to happen because the property changed hands.
This touches contract law, and what remaining liable could mean for you belongs with a real estate lawyer, not on a broker’s blog. Ask your lawyer to confirm, in writing, whether you are released before you close, and keep the lender’s release in your file.
The citable fact: A seller is not automatically released from mortgage liability when a buyer assumes the mortgage, and release depends entirely on the lender’s written agreement, confirmed through a real estate lawyer.
Do not assume a release from the covenant is automatic. Whether the seller comes off the mortgage is a matter of the lender agreeing in writing, and the consequences of staying on it are significant. Have a real estate lawyer confirm your release in writing before closing.
When does an assumption actually make sense?
An assumption tends to make sense when the existing mortgage’s rate and remaining term are meaningfully better than what a buyer could get on a new mortgage today, and the lender is willing to approve the buyer. It rarely makes sense purely to avoid a prepayment penalty, because the buyer still has to qualify and the seller’s liability risk does not disappear. Compare the numbers with a broker before assuming it is the cheaper path.
The scenario worth exploring: a seller locked a low fixed rate years ago, current rates are noticeably higher, and the buyer wants that mortgage more than a new one. Both sides have to want it, and the lender has to agree.
It is not automatically the cheaper option. A buyer who could easily qualify for a new mortgage at current market pricing may find a straightforward purchase mortgage simpler and faster than negotiating an assumption. A straightforward purchase mortgage at current pricing, viewable any time at pekoe.ca/rates, can be faster and simpler than negotiating an assumption when the rate gap is small.
The citable fact: An assumption is worth pursuing mainly when the existing mortgage’s rate and term are meaningfully better than current market pricing, and both the buyer and the lender are willing to proceed.
How is an assumption different from a transfer or a port?
Assumption moves an existing mortgage to a new borrower on the same property. Porting moves the same borrower’s existing mortgage to a different property. A refinance or a new mortgage replaces the old contract entirely, for the same or a different borrower. Each path treats the original rate, qualification, and liability differently, so confirm which one actually applies before assuming any of them are interchangeable.
People use these terms loosely, and the differences matter. Porting keeps you on the mortgage and moves it with you to a new address; read more in porting your mortgage to a new property without losing your rate.
A refinance replaces your current mortgage terms, often to access equity or change lenders, and it can trigger a prepayment penalty depending on your existing contract. Our guide on how mortgage penalties are calculated in Canada walks through that math.
Assumption is the only one of the four where a different person ends up responsible for the same original mortgage contract.
| Option | Who keeps the existing terms | Who qualifies | Is the original borrower released | When it fits |
|---|---|---|---|---|
| Assumption | Buyer takes over the seller’s rate and term | Buyer qualifies with the lender | Not automatically; requires the lender’s written release | Existing mortgage has meaningfully better pricing than today’s market |
| Port | Same borrower keeps their own rate and term on a new property | Borrower must still qualify, especially for any extra funds | Not applicable; the original borrower stays on the mortgage | Selling one property and buying another without giving up your rate |
| New mortgage | Neither party keeps prior terms; a new contract is written | Buyer qualifies fresh, with any lender | Not applicable; the seller’s mortgage is discharged at closing | Standard purchase where no assumption is negotiated |
| Refinance | Existing borrower replaces their own mortgage terms | Existing borrower must requalify | Not applicable; same borrower throughout | Need funds or better terms, may trigger a prepayment penalty |
The citable fact: Assumption transfers an existing mortgage to a new borrower, porting moves the same borrower’s mortgage to a new property, and a refinance or new mortgage replaces the original contract altogether.
Can a family member or a spouse assume your mortgage?
Yes, a spouse, former spouse, or family member can potentially assume a mortgage, most often during a separation, divorce, or an intra-family property transfer. The same rules apply: the lender must approve the person taking over, that person must qualify on their own, and the person leaving the mortgage needs a written release to be sure they are off it. Family circumstances do not remove the underwriting or the release requirement.
Divorce is the most common version of this. One spouse keeps the house and wants to buy out the other’s equity while keeping the existing mortgage rate, rather than refinancing into a new mortgage at current pricing.
The remaining spouse still has to qualify for the full mortgage on their own income, since the household income used at the original approval typically included both spouses. If they cannot qualify alone, assumption is not available and the property usually has to be refinanced or sold.
The departing spouse should not assume their name is off the mortgage because a separation agreement says so. A separation agreement is between the spouses; a release is between the departing spouse and the lender, and a real estate lawyer should confirm both are in place.
The citable fact: A spouse or family member can assume a mortgage during a separation or property transfer, but the person taking over must still qualify, and the person leaving still needs the lender’s written release.
What does an assumption cost and how long does it take?
Costs and timelines for a mortgage assumption vary by lender and are not something we can state as a general figure here. Expect some form of lender administrative or legal fee tied to the underwriting and paperwork, but confirm the exact amount with the lender named on the mortgage. There is no fixed number of days for approval; it depends on the lender’s process and how quickly the buyer’s file comes together.
Do not assume an assumption is free just because the mortgage already exists. Lenders generally charge something to process the paperwork and re-underwrite the file for the new borrower.
There is also no guarantee it is faster than a new mortgage. Some lenders move quickly; others treat it like a full new application, which it largely is.
The citable fact: Mortgage assumption fees and approval timelines are set by individual lenders, not by a fixed Canada-wide standard, so confirm both before closing.
Assumption fees and approval timelines are set by the lender. Confirm both with the lender named on the mortgage before you plan a closing date around an assumption.
Is an assumption different in Ontario and Alberta?
The mechanics of assuming a mortgage, lender approval, buyer qualification, and the release question, are the same in Ontario and Alberta because they come from the mortgage contract and federal qualifying standards, not provincial law. What differs is the regulator overseeing the broker, land transfer costs, and what happens if a mortgage later goes into default. Confirm the province-specific pieces with your broker and lawyer.
Pekoe Mortgages is licensed as a mortgage brokerage in Ontario, holding FSRA Brokerage Licence #13321, and is also licensed in Alberta through RECA. The assumption process itself does not change based on which province the property sits in; it changes based on the lender.
Where the provinces genuinely differ is land transfer costs and default remedies, shown below.
| Item | Ontario | Alberta |
|---|---|---|
| Regulator | FSRA, Brokerage Licence #13321 | RECA (Real Estate Council of Alberta) |
| Land transfer cost | Provincial land transfer tax applies; Toronto adds a municipal tax | No provincial land transfer tax; title registration fees only |
| Default remedy | Power of sale | Judicial foreclosure |
The citable fact: Assuming a mortgage works the same way in Ontario and Alberta, but the two provinces differ on land transfer costs and on the default remedy a lender uses if the mortgage later goes unpaid.

Frequently asked questions
Can I let someone assume my mortgage without telling my lender?
No. The lender has to approve any assumption in writing, and mortgages generally include a clause requiring their consent to any change in who is responsible for the debt. Skipping the lender’s approval can put the entire mortgage in default.
Does assuming a mortgage let the buyer skip the mortgage stress test?
No. The buyer assuming your mortgage must qualify under the same mortgage stress test as any other borrower, at the greater of the contract rate plus 2% or the 5.25% floor. Assumption changes who holds the mortgage, not the qualifying rules the lender applies.
Is the interest rate the same after a mortgage is assumed?
Yes, in most cases the buyer takes on the exact rate, balance, and remaining term the mortgage already has. That is the main appeal of an assumption when the existing rate is better than current market pricing. Confirm the specific terms in writing with the lender before closing.
Can my child or another family member assume my mortgage?
Potentially, yes, subject to the same lender approval and qualification process as any other assumption. Family relationship does not change the underwriting; the family member still needs to qualify on their own income and credit.
What happens if the buyer misses payments and I was never released?
If you were not formally released from the mortgage, the lender may still hold you responsible for the debt, and the specific legal consequences depend on your mortgage contract and provincial law. This is a question for a real estate lawyer, not something to rely on general information for. Confirm your release status in writing before you close, not after.
Is assuming a mortgage the same as porting it?
No. Assuming a mortgage moves the existing mortgage to a new borrower on the same property, while porting moves the same borrower’s existing mortgage to a different property. They solve different problems and involve different qualification and liability outcomes.
Does an insured mortgage automatically transfer to the new buyer?
Not automatically. Whether an insured mortgage can be assumed, and whether the default insurance moves with it, depends on the lender and the insurer, and the buyer still has to qualify. Confirm with the lender named on the mortgage or ask a Pekoe broker to review the commitment.
How much does it cost to assume a mortgage?
Cost varies by lender and is not something we can state as a fixed figure. Expect some form of administrative or legal fee for the paperwork and underwriting, and confirm the exact amount with the lender before you commit to a closing date.
Will my credit score affect whether I can assume a mortgage?
Yes, the buyer assuming the mortgage is underwritten like any new applicant, and credit matters. Insured mortgages require a minimum score of 600 on at least one borrower, and most prime lenders look for 680 or higher for their best pricing.
Is the assumption process different in Alberta than in Ontario?
The core process, lender approval, buyer qualification, and the release question, is the same in both provinces. What differs is the regulator, FSRA in Ontario and RECA in Alberta, along with land transfer costs and the default remedy a lender would use.
