HELOC in Canada: how it works, limits, rates and costs

Short answer: A HELOC in Canada is a home equity line of credit: a revolving credit limit secured against your home that you can draw on, repay and reuse ^[1]. The revolving portion can be up to 65% of your home's value, and up to 80% when it's combined with a mortgage ^[1][2]. Rates are usually variable, based on the lender's prime rate, and you pay interest only on what you've borrowed ^[1].

That flexibility makes a HELOC one of the most useful tools a homeowner can have, for renovations, an emergency cushion or consolidating higher-interest debt. It also means a HELOC rewards a plan. This guide explains how the limits are calculated, what drives the rate, how lenders qualify you, what it costs to set up, and the habits that keep a HELOC working for you.

What is a HELOC and how does it work?

A home equity line of credit is a form of revolving credit secured by your home ^[1]. Your lender approves a credit limit. You move money out when you need it, by online transfer, cheque or an access card, and the room comes back as you repay ^[1]. Interest is charged only on the balance you've drawn, starting from the day you take the money out ^[1].

Payments are flexible. Depending on the lender, your minimum payment may be interest only, or interest plus part of the principal, and you can repay any amount at any time ^[1].

Because your home is the security, the lender registers a charge on your title. If you sell the home, the HELOC has to be paid off, and if you don't repay what you owe, the lender can take steps to recover it from the property ^[1]. That's the trade-off for a rate that's usually lower than an unsecured line of credit or a credit card ^[1].

Standalone vs readvanceable HELOCs

There are two main types, and the difference matters for your limit and for switching lenders later ^[1].

Readvanceable plans can also let you split the mortgage side into several fixed or variable portions. Some plans allow several mortgage portions and lines of credit under one global limit, so ask how many segments a lender allows.

How much can you borrow with a HELOC?

Two rules work together:

1. The 65% rule. OSFI, the federal regulator of banks, expects lenders to cap the non-amortizing (revolving) HELOC portion at 65% of the property's value. Borrowing beyond 65% has to be set up as an amortizing loan, such as a regular mortgage portion ^[2].
2. The 80% rule. A bank can't make an uninsured loan to buy, renovate or improve a home if that loan, together with any mortgage ranking ahead of or equal to it, would exceed 80% of the home's value ^[3]. FCAC applies the same 80% ceiling when it explains borrowing against home equity ^[7], and 20% equity is the minimum for a HELOC combined with a mortgage ^[1].

Lenders also apply their own policies. OSFI expects them to lend less than the maximum when the risk is higher, for example because of the property's location or type, or the borrower's profile ^[2].

Here's how those rules play out on an $800,000 home:

Illustrative maximums based on the 65% and 80% rules ^[1][2][3]. Your actual limit depends on the appraisal, your income, credit and the lender's policy, OAC.

From our desk: A limit is not a target. Many clients ask for a smaller limit than they qualify for, which FCAC also suggests if a large limit could tempt you to overspend ^[1]. You can usually ask for an increase later if your plans change.

Limits that step down over time

Some readvanceable plans reduce the overall limit over time. A plan might start with a global limit of up to 80% of your home's value and then reduce it gradually toward 65%, the cap on the revolving portion ^[2]. Ask any lender whether its limit is fixed or reduces over time, because it affects how much room you'll have later.

HELOC rates in Canada: how they're set

Most HELOCs have a variable rate tied to the lender's prime rate, quoted as prime plus or minus a spread ^[1]. FCAC's own example is a HELOC at prime plus 1% ^[1].

• Prime rate: major lenders' prime rate is 4.70% as of November 2026. It usually moves when the Bank of Canada changes its policy rate, which it raised to 2.5% on October 28, 2026 ^[5]; the next scheduled decision is December 9, 2026.
• Your spread: set by the lender, and often negotiable, depending on your credit, equity, the size of the limit and the lender ^[1].
• Rate changes: the lender can change your HELOC rate at any time. Federally regulated lenders must tell you in writing within 30 days of a change ^[1].

Illustration only, not a quote. Spreads vary by lender and borrower; your rate depends on your situation, OAC. Interest shown is simple monthly interest on the balance.

As the table shows, a 0.25-point change in prime moves the interest on a $50,000 balance by about $10 a month.

Qualifying for a HELOC

Lenders look at four things ^[1][2]:

• Equity: more than 35% for a standalone HELOC, or 20% for a HELOC combined with a mortgage ^[1].
• Income and debts: you must be able to carry the payments alongside your other obligations. Banks must stress-test uninsured borrowing at the greater of 5.25% or your contract rate plus 2% ^[4]. For a HELOC at 5.45%, that means qualifying at 7.45%.
• Credit history: your track record of repaying debt on time ^[2].
• The property: an appraisal or other valuation confirms the value the limit is based on ^[1][2].

How a lender counts a HELOC in your debt ratios varies. In our experience, many lenders assume the full limit is drawn and repaid over a set period at the qualifying rate. For illustration, a $100,000 limit treated that way over 25 years at 7.45% works out to a qualifying payment of roughly $736 a month, even if your balance is zero. That's one reason a very large limit can reduce what you qualify for elsewhere.

You'll usually be asked for proof of ownership, your mortgage details (balance, term and amortization), income documents and an appraisal, and you'll sign with a lawyer or notary who registers the charge ^[1].

What does a HELOC cost to set up?

There's no prepayment penalty on the revolving portion, but set-up and closing can involve several fees ^[1]:

Some lenders cover part of the set-up costs, so ask. If you add a HELOC as part of a refinance or at renewal, the legal work can often be combined, which can keep costs down.

One more cost to know about: HELOCs and readvanceable mortgages are commonly registered as a collateral charge. If you later want to switch lenders, FCAC notes you may have to pay to remove the charge and register a new one, and repay or transfer every loan secured by it, including lines of credit ^[6]. Our mortgage renewal guide covers how that affects switching at renewal.

Interest-only payments: a worked example

The minimum payment on many HELOCs covers interest only ^[1]. That keeps payments low, but it doesn't reduce the balance. Here's the difference a plan makes on a $50,000 draw at an illustrative 5.70%:

Illustration only, assuming the rate stays at 5.70% (prime 4.70% + 1%) with monthly compounding. Your rate and payments will differ, OAC.

FCAC's advice is simple: set an objective, borrow only what you need, and build a repayment schedule that includes more than the minimum ^[1]. An automatic transfer that pays the balance down on a timeline you choose does most of the work.

Pros and cons of a HELOC

Pros

• Borrow only what you need, when you need it, and pay interest only on the balance ^[1]
• Usually a lower rate than unsecured loans and credit cards ^[1]
• Repay any amount at any time without a prepayment penalty on the revolving portion ^[1]
• With a readvanceable plan, your available credit grows as you pay down the mortgage ^[1]

Cons

• The rate is usually variable, so payments rise if prime rises ^[1]
• Interest-only minimums mean the balance can linger for years ^[1][2]
• Easy access can make it tempting to borrow more than you planned ^[1]
• The lender can review your limit if your home's value falls or your finances change materially ^[2]
• Moving a collateral-charge HELOC to another lender usually involves legal costs ^[6]

HELOC vs other ways to borrow against your home

A HELOC isn't the only way to use your equity. Here's how the main options compare at a glance:

If you need a large lump sum, or want a fixed rate on the whole amount, a mortgage refinance may suit you better, though breaking a closed mortgage mid-term can carry a penalty (see what refinancing costs in Canada). If you're 55 or older and want to avoid regular payments, a reverse mortgage is another option, at a higher rate ^[9].

What people use a HELOC for

• Renovations: draw in stages as invoices come in, rather than borrowing the full amount on day one. Our renovation financing page compares the options.
• Debt consolidation: replacing high-interest card balances with a lower secured rate can cut interest, as long as the cards don't fill back up. See debt consolidation and our three worked debt consolidation examples.
• An emergency cushion: a HELOC with a zero balance costs no interest, though some lenders charge fees.
• Investing: interest on money borrowed to earn income from a business or property may be tax-deductible, depending on how the money is used ^[8]. Get tax advice first; investing with borrowed money adds risk.

How to get a HELOC through a broker

1. Check your room. Work out 80% of your home's value minus what you owe, and keep the revolving portion under 65%.
2. Decide on the structure: a standalone HELOC, or a readvanceable plan set up at a refinance, purchase or renewal.
3. Compare lenders. Look at the spread over prime, set-up costs, annual fees, whether the limit steps down over time, and how the charge is registered.
4. Apply and qualify. Expect income verification, a credit check and the stress test ^[1][4].
5. Appraisal and legal. The lender confirms the value, and a lawyer or notary registers the charge ^[1].
6. Set a repayment plan before your first draw, with an automatic payment above the interest-only minimum.

When a HELOC may not be the best fit

• You need one large amount for a fixed purpose and want a fixed payoff date. A refinance or a home equity loan builds in the repayment.
• A rising rate would strain your budget. A fixed-rate option gives more certainty than a prime-based line.
• You have less than 20% equity. A HELOC usually isn't available yet; talk to us about other options.
• You know you'll be tempted to keep borrowing. A smaller limit, or a loan with fixed payments, can be the safer choice ^[1].

A HELOC gives you flexible, lower-cost access to your home equity: up to 65% of your home's value on its own, or up to 80% combined with a mortgage, at a variable rate tied to prime. Ask for the limit you need, compare spreads and set-up costs, and set a repayment plan before your first draw, and a HELOC can serve you well for years.
