You look at your home, your mortgage balance, and you think "there's a pile of dormant capital in there." You're right — but there are three different ways to tap into it in Quebec, and they don't cost the same, don't qualify the same way, and don't suit the same projects.
The confusion comes from the vocabulary: HELOC, home equity line of credit, readvanceable mortgage, refinance, re-advance... some terms mean the same thing, others don't at all. This guide sorts it out with real 2026 Quebec market numbers.
The three options, one sentence each
- Refinance — You break (or renew) the existing mortgage and open a new, larger one. Money comes out in a lump, fixed or variable rate, full new notarial deed.
- HELOC (home equity line of credit) — A line of credit secured by the home, capped at 65% of the value, draw whenever you want. Variable rate indexed to prime.
- Readvanceable mortgage (hybrid product like Manulife One, Scotia STEP, Tangerine Home Equity Line of Credit, Desjardins All-in-One) — A combined account that mixes mortgage + line of credit under one product. Usually capped at 80% of value, with automatic re-advance as principal is paid down.
Quick comparison table
| Criteria | Full refinance | Standalone HELOC | Readvanceable mortgage |
|---|---|---|---|
| LTV cap | 80% | 65% | 80% (max 65% as line) |
| Rate type | Fixed or variable | Variable (prime + 0.5 to 1%) | Mix: fixed portion + variable portion |
| Notary fees | $1,200-1,800 | $0-800 | $1,000-1,500 at opening |
| Prepayment penalty | Yes, if mid-term | No | On the mortgage portion only |
| Repayment | Fixed amortization | Interest-only accepted | Amortization + flexible line |
| Automatic re-advance | No | Yes (up to cap) | Yes (as principal repays) |
| Best for | Lump-sum capital, want fixed rate | Spread-out expenses | Investors, self-employed |
Full refinance: when it works
The refinance is the right option when you need a specific amount, in a single draw, and you want to lock in a fixed rate for predictable debt.
Typical cases:
- Debt consolidation in a single payment
- Buying out an ex-spouse's share after separation
- Down payment for a rental property or cottage
- Major renovation with a fixed quote (turnkey addition)
The trade-off is the entry cost: $1,500 to $4,000 in notary, appraisal, and administrative fees, plus a possible IRD penalty if you break a fixed term before maturity. Details in our guide on when refinancing is worthwhile.
HELOC: when flexibility wins
The HELOC is capped at 65% of property value, a limit set by the Office of the Superintendent of Financial Institutions (OSFI). You can draw up to that cap, repay, redraw — like a credit card secured by your home.
Typical cases:
- Phased renovations (kitchen this year, bathroom next year)
- Low-cost emergency fund (access in case of job loss, no need to apply for a loan)
- Investments where capital goes out progressively
- Business start-up financing (careful: interest deductible only if use is documented)
The variable rate is indexed to the banks' prime rate (prime + 0.5% to 1% typical in 2026). It rises and falls with Bank of Canada decisions. On long-held balances, it can cost more than a fixed-rate refi. On short-term or rapidly repaid balances, it's often the cheapest option.
Readvanceable mortgage: when it becomes interesting
Combined products (Manulife One, Scotia STEP, Tangerine Home Equity Line of Credit, Desjardins All-in-One) mix a standard amortized mortgage portion + a revolving line portion, under a single global cap of 80% LTV (with a maximum of 65% in the revolving portion).
The main appeal: automatic re-advance. With every monthly payment, the principal you repay automatically frees up more available line. After a few years, you have a growing line of credit without having to reapply.
Typical cases:
- Real estate investors using the Smith Manoeuvre (tax leverage)
- Self-employed with irregular income who want to smooth out cash flow
- Disciplined households who want to centralize mortgage + line + account
The trade-off: these products are often registered as a collateral mortgage on land title (up to 125% of value), which makes transferring to another lender at renewal much more expensive. An AMF-licensed broker will walk you through the impact before you sign.
The qualification test: where it's hardest
All three options require a full new qualification, but not with the same severity:
| Option | Stress test | Income verification | Credit score impact |
|---|---|---|---|
| Full refi | Contract rate + 2% or 5.25% | Full | Hard inquiry |
| Standalone HELOC | Contract rate + 2% (often stricter) | Full | Hard inquiry |
| Readvanceable | Combined across both portions | Full | Hard inquiry |
The HELOC is often perceived as "easier," but in reality A lenders apply the stress test on the full line cap, not just on the drawn amount. Result: someone with tight ratios can qualify for a full refi and be declined for an equivalent HELOC, because the total qualifying cap is higher.
Tax impact: the detail that changes everything
In Quebec (and federally), mortgage interest is not deductible when the money is used for the principal residence (renovation, personal debt consolidation). It is deductible when the money is used to generate income (rental property, non-registered investments).
That changes the calculation:
- Refi to renovate your kitchen → no tax deduction
- HELOC to buy non-registered investments → interest deductible
- Readvanceable used to fund a rental → interest deductible proportional to invested portion
A tax specialist or a broker familiar with the Smith Manoeuvre can quantify the impact. Our article on home equity extraction digs into the topic.
Decision tree: 3 questions
-
Do I need a fixed amount, one time only?
- Yes → Full refinance
- No, it comes out in phases → HELOC or readvanceable
-
Will I use more than 65% LTV?
- Yes → Refinance (HELOC alone doesn't allow it)
- No → HELOC possible
-
Do I want automatic re-advance and am I disciplined with revolving credit?
- Yes → Readvanceable
- No → Standalone HELOC or fixed-rate refi
What Courteo does
Courteo is a matchmaking platform. An AMF-licensed mortgage broker in the Courteo network assesses your situation, compares the three options with real numbers from multiple lenders, and tells you what's actually eligible. No rates displayed, no approval promises — the broker decides based on lender policy.
Frequently asked questions on HELOC, refi and readvanceable mortgages
Can I have a HELOC and a mortgage separately with two different lenders?
Yes, it's actually common. The first-ranked mortgage stays with the original lender; the HELOC is opened as a second charge with another lender. Careful: the second-charge lender requires consent from the first-charge lender and takes a higher rate (prime + 1 to 2%). An AMF-licensed mortgage broker simulates the scenarios.
Does a HELOC count against my debt ratio for a future mortgage?
Yes, entirely. Even if you haven't drawn anything on the line, lenders qualify on the available cap, not the used balance. An unused $100,000 HELOC can reduce your future borrowing capacity by tens of thousands of dollars.
Can I convert my HELOC into a fixed-rate mortgage portion?
Most hybrid products allow it: you convert a portion of the line balance into an amortized fixed-rate tranche, with no notary fees. Useful when a portion of the debt becomes "permanent" and you want to lock it in at a fixed rate. A standalone HELOC generally doesn't allow it — you'd have to refinance fully.
What happens to my HELOC if I sell the home?
It must be repaid at sale, just like the mortgage. The notary withholds the balance from the sale proceeds. If you plan to buy again, the new property can support a new HELOC, but nothing transfers automatically.
