HELOC vs. Second Mortgage in Canada (2026): Which Is Right for You?
Both let you borrow against home equity without touching your first mortgage — but a HELOC and a second mortgage work very differently. Here's how to choose in Canada.

When you want to tap home equity but keep your existing first mortgage untouched, two tools compete: a HELOC and a second mortgage. They're often confused, but they suit very different needs. Here's a clear comparison so you pick the right one. (New to lines of credit? Start with how a HELOC works.)
The short answer
Choose a HELOC if you want flexible, reusable access at a variable rate and you qualify with a bank. Choose a second mortgage if you need a fixed lump sum, prefer predictable payments, or don't qualify for a HELOC (alternative and private second mortgages are more flexible on credit and income). Both sit behind your first mortgage, so neither disturbs your existing rate. See all equity options.
HELOC — flexible and reusable
- Structure: a revolving line of credit up to your limit — borrow, repay, borrow again.
- Rate: variable, tied to prime (4.45% in 2026).
- Payments: often interest-only on the balance used.
- Best for: staged renovations, a cash buffer, tuition, or any ongoing/uncertain need.
- Qualifying: bank HELOCs require good credit and income, and you'll pass the stress test. Capped at 65% of home value standalone.
See HELOC options and the HELOC calculator.
Second mortgage — a fixed lump sum
- Structure: a separate loan for a set amount, with a defined term.
- Rate: usually fixed; higher than a first mortgage because it's in second position.
- Payments: regular and predictable.
- Best for: a one-time need, debt consolidation, or when you don't qualify for a HELOC.
- Qualifying: alternative and private lenders are flexible on credit and income, focusing on equity — useful when banks say no.
Head to head
- Flexibility: HELOC wins (reusable). Second mortgage is one lump sum.
- Rate type: HELOC variable; second mortgage usually fixed.
- Approval: HELOCs need strong bank qualification; second mortgages (especially private) are easier with bruised credit.
- Cost: a bank HELOC is typically cheaper than a private second mortgage, but a HELOC's variable rate carries rate risk.
How to decide
Strong credit and income, want flexibility → HELOC. Need a guaranteed lump sum with steady payments, or you've been declined by a bank → second mortgage. Consolidating high-interest debt with lots of equity? A full refinance may beat both — compare in how to use your home equity and debt consolidation.
Frequently asked questions
Is a HELOC cheaper than a second mortgage?
Usually a bank HELOC has a lower rate, but it's variable. A second mortgage (especially private) costs more but offers a fixed rate and easier approval with weaker credit.
Can I get a second mortgage with bad credit?
Yes — alternative and private lenders offer second mortgages based on your equity rather than your credit score, which is harder to do with a bank HELOC.
Do either affect my first mortgage?
No. Both sit behind your first mortgage, so your existing rate and term are untouched — there's no break penalty.
How much can I borrow with a HELOC or second mortgage?
Combined with your first mortgage, generally up to 80% of your home's value; a standalone HELOC is capped at 65%. Your qualifying income and lender set the final limit.
