What Is a HELOC?
A Home Equity Line of Credit (HELOC) is a revolving line of credit secured against your home. Think of it like a credit card, but with your home as collateral and interest rates that are much lower, typically prime + 0.5% to prime + 1%, which in 2026 works out to roughly 5–6%.
As you pay down your mortgage and/or your home's value increases, you build equity. A HELOC lets you borrow against that equity as needed, repay it, and borrow again.
How Much Can You Borrow?
In Canada, the rules are set by the Office of the Superintendent of Financial Institutions (OSFI):
- You can borrow up to 65% of your home's appraised value via a HELOC alone
- Combined mortgage + HELOC cannot exceed 80% of your home's value
Ottawa example: Your home is appraised at $700,000. You owe $350,000 on your mortgage.
- 80% of $700,000 = $560,000
- Minus your mortgage balance of $350,000 = $210,000 available as HELOC
Note: Even though 65% of $700,000 is $455,000, the combined 80% cap limits you to $210,000 in this scenario.
How Is It Different from a Mortgage?
| Feature | Mortgage | HELOC | |---|---|---| | Repayment | Set schedule | Interest-only minimum; flexible | | Access | Lump sum once | Revolving, borrow, repay, borrow again | | Rate | Often fixed | Usually variable (prime + spread) | | Purpose | Home purchase | Any purpose |
A HELOC requires only interest payments each month. You're not required to repay the principal. This makes monthly costs low but means the balance can sit for years if you're not disciplined.
What Can You Use a HELOC For?
Anything. But the most common (and financially sensible) uses in Canada:
- Home renovations: Kitchen, bathroom, basement finishing, adds value to the property
- Investment: Some Canadians use HELOCs to invest in a rental property down payment (the interest may be tax-deductible if borrowed for investment purposes, consult a tax advisor)
- Education costs: Tuition for children or professional development
- Emergency fund backup: A HELOC can serve as a safety net
- Debt consolidation: Paying off high-interest credit card debt at 19% with a HELOC at 6% saves significant interest
When a HELOC Is Risky
HELOCs are powerful tools, but they carry real risks:
Your home is collateral. If you borrow heavily and can't make payments, the lender can force the sale of your home. This is not a theoretical risk.
Variable rates go up. If the Bank of Canada raises rates, your HELOC interest payments rise immediately. Budget for this.
Easy access encourages borrowing. Having $200,000 available at a click is psychologically different from a fixed loan. Some people overspend.
How to Get a HELOC
You apply through your bank or credit union. They'll require:
- A home appraisal (often a desktop appraisal for existing customers)
- Proof of income
- Credit check
- Legal work to register the HELOC against your title
The application process typically takes 2–4 weeks and costs $300–$1,000 in legal and registration fees.
For Ottawa Newcomers
If you bought your Ottawa home a few years ago and have been building equity, a HELOC is worth understanding even if you don't need it right now. Having the credit facility established costs nothing until you use it, and it can be a valuable financial tool, just use it intentionally.
