The credit-card balance is growing, the kitchen quote has arrived, and your home has equity.
On paper, the solution can look obvious: replace expensive debt with borrowing secured by the house.
But that changes more than the interest rate.
A mortgage refinance, home equity loan or home equity line of credit (HELOC) may carry a lower interest rate than unsecured debt such as a credit card. The trade-off is that the borrowing is secured by your home. If repayment becomes a problem, the consequences can therefore be much more serious.
For Canadian homeowners, a useful starting point is this: a refinance or home equity loan can fit a known amount with a defined repayment plan, while a HELOC can be better suited to expenses that arrive in stages—provided you have a plan to repay the principal.
The right choice still depends on your mortgage contract, available equity, qualification, interest rates, fees and repayment timeline.
Do not choose based only on the smallest monthly payment. Compare the total cost, repayment period, fees, rate risk and what happens if household income changes.
Quick Answer
A mortgage refinance can let you restructure your existing mortgage and potentially borrow additional money against your home.
A home equity loan provides a lump sum that is repaid through scheduled principal-and-interest payments.
A HELOC provides revolving credit secured by the home. You can borrow, repay and borrow again up to the approved limit, while paying interest only on the amount actually borrowed.
The cheapest-looking monthly payment is not necessarily the cheapest option overall. Extending debt over a longer period can increase total interest costs, and moving unsecured debt onto your home makes the property collateral.
Start with the equity you can actually use
Home equity is the difference between your home's value and the debt secured against it, including your mortgage, HELOC and other loans or lines of credit secured by the property.
A lender may require an appraisal before deciding how much you can borrow.
Consider an illustrative homeowner whose property is appraised at $600,000 and whose remaining mortgage is $360,000.
The homeowner has:
$600,000 − $360,000 = $240,000 in home equity.
But having $240,000 of equity does not mean the homeowner can borrow another $240,000.
According to the Financial Consumer Agency of Canada (FCAC), financial institutions may usually allow total borrowing secured against home equity of up to 80% of the home's value, subject to the product and lender's approval.
In this example:
80% × $600,000 = $480,000
With $360,000 already owed on the mortgage, that leaves theoretical additional borrowing room of:
$480,000 − $360,000 = $120,000
That $120,000 is not an approval or guaranteed amount.
Income, existing debts, credit history, property value, lender underwriting and the type of home-equity product can all affect the actual amount available.
FCAC also notes that borrowing against home equity may involve costs such as appraisal, title-search, title-insurance and legal fees.
See FCAC's guide to borrowing against home equity.

Mortgage refinance vs home equity loan: what's the difference?
Imagine the homeowner in our example has two bills competing for attention.
There is $28,000 of credit-card debt, where the amount is already known.
Then there is a $32,000 kitchen renovation estimate, but the contractor will bill at different stages.
Those two expenses may call for very different borrowing structures.
Mortgage refinance
A mortgage refinance changes the existing mortgage arrangement and may allow additional borrowing against the property.
It can make sense for a defined borrowing need when restructuring the existing mortgage produces acceptable overall costs.
But the interest rate is only one part of the calculation.
If you refinance a closed mortgage before the end of its term, you may face a prepayment charge. Extending the debt over a longer amortization can also reduce the monthly payment while potentially increasing how long you remain in debt.
Home equity loan
A home equity loan provides a one-time lump sum.
According to FCAC, you pay interest on the total amount borrowed and repay fixed amounts on a fixed term and schedule. Payments include principal and interest.
Once the borrowed amount has been repaid, you cannot simply borrow it again as you could with revolving credit.
That structure can fit something with a clearly defined cost—for example, a completed renovation contract or a specific amount of debt being consolidated.
The important distinction is structural: refinancing changes the existing mortgage arrangement, while a home equity loan is separate borrowing secured against the home's equity.
Where a HELOC fits
Now consider the kitchen renovation.
The contractor does not need all $32,000 tomorrow. Perhaps a deposit is required first, followed by cabinetry, electrical work and the final payment weeks or months later.
Borrowing the entire amount immediately through a lump-sum loan could mean paying interest on money before it is actually needed.
That is where a HELOC can become useful.
A HELOC is revolving credit secured by your home. You can access money up to your approved limit, repay it and borrow again.
According to FCAC, you pay interest only on the amount borrowed.
Most HELOCs have variable interest rates. Depending on the lender and product, required regular payments may cover only interest or may include principal and interest.
That flexibility is also the biggest risk.
If you continually reborrow or make only interest payments, a balance intended to last six months can remain for years. FCAC specifically warns that easy access to HELOC funds may encourage borrowers to take on more debt and that paying only interest will not eliminate the loan.
The practical rule is simple: a HELOC should have a repayment plan, not just a credit limit.
FCAC recommends establishing a clear purpose, creating a budget, borrowing only what you need and setting a repayment schedule.
Read FCAC's guide to home equity lines of credit.
Where a second mortgage fits
A second mortgage is another mortgage registered against the home while the first mortgage remains in place.
That means the homeowner must continue making payments on both.
According to FCAC, second-mortgage interest rates are usually higher than rates on first mortgages because second mortgages represent greater risk to lenders.
For some borrowers, a second mortgage may provide access to a lump sum without replacing the existing first mortgage. But its rate, fees and combined payment burden need to be compared carefully with refinancing and other alternatives.
Match the borrowing structure to the job
| Option | Can fit | Core trade-off |
|---|---|---|
| Mortgage refinance | Known borrowing amount when restructuring the existing mortgage is cost-effective | May involve prepayment charges, fees or a longer repayment period |
| Home equity loan | Defined lump-sum expense | Interest applies to the full amount borrowed |
| HELOC | Staged or uncertain expenses | Variable rates and reusable credit can prolong debt |
| Second mortgage | Lump sum while keeping the first mortgage | Usually higher rate and two secured obligations |
| Unsecured loan or line of credit | Borrowing without securing the debt against the home | Interest may be higher, but the home is not collateral for that debt |
Return to our homeowner.
The $28,000 credit-card balance is already known. If it is consolidated, the homeowner can establish a specific date by which that $28,000 should disappear.
The $32,000 renovation, however, may be billed in stages.
Drawing $8,000 today, another amount when cabinetry arrives and the remainder as work progresses can avoid paying interest on the entire renovation budget from day one.
But there is a catch.
If the homeowner pays off $28,000 of credit-card debt using home equity and then rebuilds the card balance, the household has not solved the original problem. It has added new unsecured debt while the old debt now sits against the house.
That is the real danger behind debt consolidation.
Compare every quote using the same finish line
Debt consolidation can simplify payments and may save money when high-interest debt is replaced by borrowing at a lower rate.
But a lower rate does not automatically mean a lower total cost.
FCAC warns that extending the repayment period may result in paying more interest over time. Continuing the spending habits that created the original balances can also lead to additional debt.
See FCAC's debt-consolidation guidance.
The easiest way to make a meaningful comparison is to give competing lenders the same borrowing amount and the same target payoff date.
Then compare:
- total interest through that date;
- mortgage prepayment charges, if applicable;
- appraisal and legal costs;
- title, administration, cancellation and discharge fees;
- the cost of any optional insurance you choose; and
- what the payment could become if a variable interest rate rises.
This prevents a common comparison mistake.
Suppose one option offers a noticeably smaller monthly payment only because the debt is being repaid over many more years. Comparing monthly payments alone makes that option look cheaper even though the borrower may remain in debt much longer.
Compare the finish line, not just the starting payment.
Breaking, refinancing or transferring a mortgage before the end of its term may result in a prepayment charge depending on the mortgage contract.
Federally regulated lenders must provide information about mortgage prepayment privileges and charges.

Understand the HELOC limits
The borrowing limits deserve special attention because the 80% home-equity figure and 65% HELOC figure are not interchangeable.
FCAC says you may generally borrow up to 65% of your home's value through a HELOC.
To qualify, you need minimum equity of:
- more than 35% for a standalone HELOC; or
- 20% for a HELOC combined with a mortgage.
Applicants must also pass a stress test to qualify for a HELOC at a bank.
The broader home-equity borrowing limit may usually reach 80% of the property's value, but that does not mean the entire 80% can necessarily be borrowed as a HELOC.
The lender will also consider the debt already secured against the property and its qualification requirements.
Test the payment before signing
A lower monthly payment is not automatically safer.
Sometimes it simply means the debt lasts longer.
For a variable-rate HELOC, ask what happens if the interest rate rises. FCAC notes that most HELOCs have variable rates and that rate changes may increase minimum monthly payments.
For any secured borrowing, run another test:
What happens if household income drops temporarily?
Imagine the homeowner consolidates the credit cards and starts the renovation. Six months later, one household income is interrupted.
The house did not become less valuable overnight—but the monthly obligations suddenly became much harder to carry.
That is why affordability should be tested against an uncomfortable scenario, not only today's budget.
For additional context on variable-rate exposure, see TwikUp's Canada mortgage rate outlook.
Most importantly, remember what makes home-equity borrowing different from a credit card or unsecured personal loan:
your home is collateral.
If you do not repay what you owe, the lender may ultimately take possession of the property.
Make the final decision
Before moving debt onto your home, ask five questions:
-
Is the amount known now?
A refinance or home equity loan may fit a defined lump-sum need. -
Will costs arrive in stages?
A HELOC may let you borrow only as money is needed, but it should come with a principal-repayment plan. -
What is the all-in cost?
Include interest, mortgage penalties and every applicable appraisal, legal, title, administration or discharge cost. -
When will the debt reach zero?
A smaller monthly payment means little if it keeps the debt alive for years longer. -
What happens if income falls or rates rise?
If the resulting secured payments could put the home at risk, keeping some borrowing unsecured—or seeking debt advice before borrowing more—may deserve consideration.
The best home-equity product is therefore not necessarily the one offering the largest credit limit or smallest first payment.
It is the one whose cost, structure and repayment timeline match the problem you are actually trying to solve.
And if existing debt has already become difficult to manage, consider speaking with a reputable credit counsellor or Licensed Insolvency Trustee before turning more of that debt into borrowing secured by your home.
Frequently asked questions
Is a HELOC the same as a home equity loan?
No. A HELOC is revolving credit secured by your home. You can borrow, repay and reuse available credit up to the approved limit.
A home equity loan provides a one-time lump sum that is repaid according to a fixed term and schedule.
Can I use a HELOC to consolidate credit-card debt?
A HELOC may be used for debt consolidation.
However, doing so changes the risk profile of the debt because the HELOC is secured by your home. A lower interest rate may also fail to produce savings if repayment is stretched over a much longer period or new credit-card balances accumulate.
Does refinancing always cause a mortgage penalty?
No.
Whether a prepayment charge applies depends on the mortgage contract and when and how the mortgage is refinanced or paid out. Closed mortgages may restrict how much you can prepay without a charge, while open mortgages generally provide greater prepayment flexibility.
Check your mortgage agreement and obtain the actual payout or prepayment-charge amount from your lender before comparing refinancing offers.
How much can I borrow against home equity in Canada?
According to FCAC, financial institutions may usually allow borrowing secured against home equity of up to 80% of the home's value, subject to the type of product, existing secured debt and lender approval.
A HELOC may generally provide borrowing of up to 65% of the home's value.
These figures are maximum parameters, not guaranteed approvals.
