Your home has built up equity. Now you want to use it. Two options come up almost every time: a second mortgage or a HELOC. They both let you access the equity you've built, but they work very differently, and choosing the wrong one can cost you.
This guide breaks down exactly how each product works, what they cost, who qualifies, and which one fits which situation. No jargon. Just the information you need to make the right call.
How a second mortgage works in Canada
A second mortgage is a lump-sum loan secured against the equity in your home, sitting behind your first mortgage in priority. If you owe $400,000 on a $700,000 home, you have roughly $300,000 in equity. A second mortgage lets you borrow against a portion of that (typically up to 80% of the property's appraised value combined with your first mortgage).
You receive the full amount upfront. Repayments are fixed: the same principal and interest amount comes out every month for the term of the loan, usually six months to two years for a private second mortgage.
The interest rate on a second mortgage is higher than a conventional first mortgage. That's the lender's compensation for sitting in second position. If the property ever went into power of sale, the first mortgage gets paid out before a cent reaches the second. Private lenders offering second mortgages typically charge 8-14% depending on the loan-to-value ratio, the property type, and the borrower's overall file.
Second mortgages are typically used for large one-time capital needs (business investment, debt consolidation, renovation), situations where the borrower can't qualify for a bank refinance, and bridge financing while a longer-term solution is arranged.
A second mortgage has an end date. When the term expires, the full balance is either paid out, refinanced, or rolled into a new term. It's a structured, time-limited product. That's exactly what some borrowers need and exactly what others find constraining.
How a HELOC works in Canada
A HELOC is a Home Equity Line of Credit: a revolving credit facility secured against your home. Instead of receiving a lump sum, you get a credit limit you can draw from, repay, and draw from again. Think of it like a very large secured credit card, except the interest rates are much lower.
Under OSFI rules, Canadian lenders can issue a HELOC up to 65% of your home's appraised value. Combined with a first mortgage, the total can't exceed 80% loan-to-value. On a $700,000 home with a $400,000 first mortgage, your HELOC limit would be capped at $160,000 ($700,000 x 80% = $560,000, minus the $400,000 mortgage).
HELOC interest rates in Canada track the prime rate. They're variable, so your payment changes when the Bank of Canada moves rates. In a rising-rate environment, HELOC costs go up. In a falling-rate environment, they go down. Most HELOCs require interest-only payments during the draw period, with no mandatory principal repayment as long as you stay within your limit.
HELOCs work well for ongoing, variable needs: home renovations done in stages, a business with fluctuating capital requirements, or an investment property down payment being built up over time. Flexible product, flexible use.
The catch: most Canadian banks require a strong credit score (typically 680+) and verifiable employment income to approve a HELOC. Self-employed Canadians and business owners with non-standard income often get declined. Private lenders can offer HELOCs with more flexible qualification criteria, though typically at higher rates. If that's your situation, HELOCs for self-employed Canadians covers the private-lender route in detail.
Second mortgage vs. HELOC: side-by-side comparison
Here's how the two products stack up across the factors that matter most.
| Feature | Second Mortgage | HELOC |
|---|---|---|
| How you receive funds | Lump sum upfront | Draw as needed, up to credit limit |
| Repayment structure | Fixed monthly principal + interest | Interest-only (minimum); flexible repayment |
| Interest rate type | Fixed for the term | Variable, tied to prime rate |
| Rate range (Canada, 2026) | 8-14% (private lender) | Prime + 0.5-1% (bank); higher with private |
| Term length | 6 months to 2 years (private) | Revolving, no fixed end date |
| Max LTV | Up to 80% combined LTV | 65% HELOC + up to 80% combined with first mortgage |
| Qualification (bank) | Credit score, income, stress test | Credit score 680+, income, stress test |
| Qualification (private) | Equity-based, more flexible | Available, more flexible than banks |
| Best for | Large one-time needs, consolidation | Ongoing, variable capital needs |
| Prepayment flexibility | Often open; depends on lender | Repay and redraw freely |
So which one should you choose? A homeowner in Kelowna has $280,000 in equity on a paid-down rental property. She needs $150,000 to fund a second investment property purchase on a specific date. She doesn't need a revolving credit line. She needs the full amount upfront. A second mortgage is the right product. A HELOC would give her a credit limit, but drawing $150,000 at once on a variable rate with no structured repayment doesn't match the transaction she's actually doing.
The right product isn't the cheaper one on paper. It's the one that fits the shape of what you actually need the money for.
Who qualifies and where to apply
For both products at a Canadian bank, the primary qualification test involves your gross debt service ratio (GDS) and total debt service ratio (TDS). GDS measures what percentage of gross income goes to housing costs (mortgage, taxes, heat, half of condo fees). TDS adds all other debt obligations. Under OSFI guidelines, banks apply a stress test requiring you to qualify at the contract rate plus 2%, or 5.25%, whichever is higher.
For a HELOC, most major banks also want a credit score of 680 or higher and employment income verifiable with a T4 or Notice of Assessment. Self-employed borrowers, anyone with newer businesses, or those with credit blemishes often don't pass this screen.
For a second mortgage at a bank or B lender, the bar is similar, though B lenders (trust companies, credit unions, and alternative institutional lenders) have more flexibility than the Big Six.
Private lenders change the picture entirely. They underwrite primarily on equity. They're looking at the loan-to-value ratio, the property itself, and a reasonable exit strategy, not primarily your T4 or credit score. A self-employed business owner in Mississauga who can't get a HELOC from her bank because her income flows through a corporation can still access $200,000 in equity through a private second mortgage. The equity is real. The lender just needs to believe they'll be repaid.
If you've been declined for a HELOC or can't qualify for a bank second mortgage, a private lender is worth exploring before assuming equity access is off the table.

Frequently Asked Questions
Can you have both a HELOC and a second mortgage at the same time?
Yes, in some cases. A HELOC typically sits in second position behind the first mortgage, but it's possible to have a first mortgage, a HELOC as a second charge, and an additional registered charge if there's enough equity. The combined loan-to-value across all registered charges generally can't exceed 80% of the property value with most lenders. Structure depends on the lender, property value, and your existing obligations.
Is a second mortgage or a HELOC better for debt consolidation?
A second mortgage is usually better for debt consolidation. You receive a lump sum, pay out the debts, and have a single fixed monthly payment for the term. A HELOC works for consolidation too, but the revolving structure means some borrowers re-accumulate debt on the cards they just paid off. If payment discipline is a concern, the structured repayment of a second mortgage typically produces better outcomes.
What happens to my HELOC if I sell my house?
The HELOC must be paid out and the registered charge discharged when the property sells. Your lawyer handles this at closing. The outstanding balance comes off the sale proceeds before you receive your equity. If you're carrying a HELOC balance, factor it into your net proceeds calculation before accepting any offer.
Do I need a new appraisal to access my home equity?
In most cases, yes. Lenders want an appraisal to confirm current market value before lending against it. Some banks use an automated valuation model (AVM) for straightforward refinances in well-documented markets, which can skip the in-person appraisal. Private lenders almost always require a full appraisal, especially for properties outside major urban centres where automated valuations are less reliable.
How fast can I access home equity in Canada?
Through a bank HELOC or second mortgage, expect two to four weeks once your application is complete. Private lenders move faster. A straightforward second mortgage with a clean title can often be funded in five to ten business days for approved files. Speed depends on how quickly the appraisal, title search, and legal work can be completed. If you need capital urgently, private lenders are typically the faster path.
