A HELOC in 2027 costs prime plus a spread, and prime was 4.70% in November 2026, so many lines sit near 5% to 6%. You can draw up to 65% of your home’s value, or 80% with your mortgage. Use it for planned, short-term needs with a payoff plan, because the rate floats and lenders can cut limits.
This guide is for GTA homeowners who have a home equity line of credit, or are thinking about opening one, and want to use it well in 2027. You will see what HELOCs cost after the October 2026 rate hike, how much you can borrow, the risks that catch people out, and the uses that tend to make sense.
What is a HELOC and how does it work?
A home equity line of credit (HELOC) is a revolving loan secured by your home. You get a credit limit, borrow what you need, repay it, and borrow again. The Financial Consumer Agency of Canada (FCAC) explains that you pay interest only on the amount you use, and your lender may require interest-only payments or interest plus some principal.
There are two main types:
- A HELOC combined with a mortgage. Sold by the same lender as your mortgage, often under a brand name. As you pay down the mortgage, your available credit can grow. It is sometimes called a readvanceable mortgage.
- A standalone HELOC. Separate from your mortgage, and possible even if you have no mortgage at all.
Because your home secures the loan, the rate is usually lower than a credit card or unsecured loan. The flip side, as FCAC puts it plainly, is that you could lose your home if you do not pay it back.
What are HELOC rates in 2027?
Most HELOCs float with your lender’s prime rate. On 28 October 2026 the Bank of Canada raised its policy rate to 2.50%, and big-bank prime rose from 4.45% to 4.70% the next day. RBC listed its prime at 4.70% on 10 November 2026. Every HELOC tied to prime went up by 0.25 points overnight.
Your rate is prime plus a spread that your lender sets. FCAC uses prime plus 1% as its example and notes you may be able to negotiate. It also says your lender can change a HELOC rate at any time, and a federally regulated lender must tell you in writing within 30 days.
Here is what interest-only payments look like at different rates.
| HELOC rate | What it represents | Monthly interest on $50,000 | Monthly interest on $100,000 |
|---|---|---|---|
| 4.70% | Prime as of November 2026 | $196 | $392 |
| 5.70% | Prime + 1% (FCAC’s example spread) | $238 | $475 |
| 6.20% | Prime + 1% if prime rises another 0.50 points | $258 | $517 |

Will prime move in 2027? The Bank of Canada said a further increase could be needed and that it will proceed carefully. Its next decision is on 9 December 2026, and its next Monetary Policy Report is due on 27 January 2027. My post on whether rates will go down in 2027 rounds up what the banks forecast.
How much can you borrow with a HELOC?
The revolving HELOC part is capped at 65% of your home’s value. FCAC states this limit, and it comes from the federal bank regulator, OSFI, whose Guideline B-20 limits the non-amortizing HELOC portion to 65% loan-to-value. Combined with a mortgage, total borrowing can reach 80% of value, but anything above 65% must be amortized, meaning paid down on a schedule. FCAC also says you need more than 35% equity for a standalone HELOC and 20% for one combined with a mortgage.
Here is what those limits look like on typical GTA home values.
| Home type (GTA benchmark) | Benchmark price, Oct 2026 | 65% (revolving cap) | 80% (total cap) |
|---|---|---|---|
| All homes (composite) | $916,400 | $595,660 | $733,120 |
| Detached | $1,194,200 | $776,230 | $955,360 |
| Semi-detached | $914,300 | $594,295 | $731,440 |
| Townhouse | $662,200 | $430,430 | $529,760 |
| Condo apartment | $521,600 | $339,040 | $417,280 |
Source: TRREB Market Watch, October 2026, MLS Home Price Index benchmarks for all TRREB areas. Your appraised value will differ. Subtract your mortgage balance from the 80% figure to see your total room.
Example: on a home at the composite benchmark with a $450,000 mortgage, total room is about $733,120 minus $450,000, or $283,120, before the lender’s own limits. FCAC suggests asking for a lower limit than you are offered so the extra credit does not tempt you.
Free tool — what can you actually afford?
Do you need to pass the stress test for a HELOC?
Yes, at a bank. FCAC says you must pass a stress test to qualify for a HELOC at a bank, which means proving you could afford payments at a higher qualifying rate. Expect the lender to ask for:
- Proof that you own the home
- Your mortgage balance, term and amortization
- A home appraisal
- A lawyer to register the home as security
Costs can include appraisal, legal, title search, administration and sometimes monthly fees. Closing a HELOC later can bring cancellation and discharge fees, so ask before you sign.
What are the biggest risks of a HELOC in 2027?
Interest-only payments never clear the debt
FCAC warns that if you pay only the interest, you will not pay off the loan. Compare two ways of carrying $50,000 at 5.70%:
- Interest only for five years: about $238 a month, about $14,250 of interest, and you still owe $50,000.
- Paid off over five years: about $960 a month and about $7,581 of interest in total.
Your rate can rise at any time
With prime at 4.70% and the Bank of Canada open to another hike, a large balance can become expensive quickly.
Your limit can shrink if prices fall
OSFI’s Guideline B-20 expects lenders to review a HELOC’s authorized amount when the property’s value falls materially or the borrower’s finances change. The GTA composite benchmark was down 4.3% year over year in October 2026, so do not treat an unused limit as guaranteed money.
It ties you to your lender
If your HELOC and mortgage sit under a collateral charge, FCAC explains that this type of charge can secure several loans and may be registered for more than your mortgage. FCAC also says that before you transfer a HELOC you must pay it off and close it, usually with legal, administrative and discharge fees. That adds cost and effort if you want to switch lenders at renewal.
It must be repaid when you sell
FCAC notes that you must repay your HELOC if you sell your home. My guide to selling a house with a HELOC explains how that works on closing day.
What are smart ways to use a HELOC?
- Staged renovations. You draw as invoices arrive and pay interest only on what you have used. Projects that add lasting value or rent, such as a legal suite or energy upgrades, make the strongest case. See which renovations tend to pay back in the GTA.
- A safety net you rarely touch. An open, unused line can cover a true emergency, such as a job loss, but remember the lender can reduce it.
- Replacing expensive debt, with a plan. FCAC lists debt consolidation as a common use. Set a fixed monthly payment that clears it in a few years.
- Investing, carefully. The Canada Revenue Agency allows a deduction for most interest on money borrowed to earn investment income, such as interest and dividends, but not when the only possible return is a capital gain. Keep borrowed money in a separate account and speak to an accountant first.
When should you avoid using a HELOC?
FCAC suggests planning HELOC use around goals such as home repairs or education rather than vacations or shopping. I would add three more red flags:
- Using it to make your mortgage payments. That is a sign the budget needs fixing, not more debt.
- Funding things that lose value fast, like a car or a holiday, over years of interest.
- Borrowing for a down payment on a second property without a plan for when rates or prices move against you.
HELOC, refinance or home equity loan: which fits in 2027?
| Option | Limit | Rate | How you get the money |
|---|---|---|---|
| HELOC | Up to 65% of value | Variable, moves with prime | As needed, by online banking, cheque or card |
| Home equity loan | Up to 80% of value | Fixed or variable, generally higher than a mortgage | One lump sum, repaid on a schedule |
| Second mortgage | 80% of value, minus your first mortgage | Generally higher than a first mortgage | One lump sum |
| Borrowing back prepayments | What you prepaid | Blended or the same as your mortgage | Lump sum added to your mortgage |

A full refinance can also work for a large lump sum you will carry for years, because mortgage rates are usually below HELOC rates, but it may trigger a penalty. My comparison of HELOC vs refinance vs selling walks through that choice.
In my view, a HELOC is a tool for planned, short-term borrowing, not a second income. Treat every draw like a loan with its own end date. If you cannot see how a balance gets to zero within a few years, a fixed-rate option or a smaller project is usually the safer choice in 2027.
A HELOC balance that grows quietly can trap you when you want to sell or switch lenders. The full balance must be repaid when you sell, and a line under a collateral charge has to be paid off and closed before you can move to another lender. Check your total secured debt at least once a year.
What to do next
- Check your HELOC rate, spread and current balance, and work out the cost if prime rises another 0.50 points.
- Set a fixed monthly payment that includes principal, and turn on balance alerts.
- Ask your lender to lower any limit you do not need.
- Before a big draw, compare the cost with a refinance or home equity loan in writing.
- If you plan to sell in the next few years, map how the HELOC will be paid off at closing.

Frequently asked questions
What is the HELOC rate in Canada right now?
Most HELOCs are priced at prime plus a spread. Big-bank prime rose to 4.70% on 29 October 2026 after the Bank of Canada’s hike, so a HELOC at prime plus 1% costs 5.70% heading into 2027. Spreads vary by lender and borrower, and lenders can change a HELOC rate at any time.
How much can I borrow with a HELOC in Ontario?
The revolving HELOC portion can reach 65% of your home’s value, and total secured borrowing, including your mortgage, can reach 80%. On a $916,400 home with a $450,000 mortgage, that leaves about $283,000 of total room in 2027, before the lender’s own limits, income checks and the stress test.
Should I use my HELOC in 2027?
Use a HELOC in 2027 for planned, short-term needs such as a staged renovation or replacing costlier debt, with a firm repayment plan. Avoid it for spending or for covering mortgage payments. With prime at 4.70% and another Bank of Canada hike possible, interest-only balances can get expensive quickly.
Do I have to pass the stress test to get a HELOC?
Yes, at a bank. FCAC says you must pass a stress test to qualify for a HELOC at a bank in Canada, proving you could afford payments at a higher qualifying rate. Expect an appraisal, proof of ownership, your mortgage details and legal fees to register the line against your home.
Can my bank lower or freeze my HELOC limit?
Yes. OSFI’s Guideline B-20 expects lenders to review a HELOC’s authorized amount when a home’s value falls materially or the borrower’s finances change. With the GTA benchmark price down 4.3% year over year in October 2026, treat an unused HELOC limit in 2027 as useful access, not guaranteed money.
Is HELOC interest tax deductible in Canada?
Only in some cases. The Canada Revenue Agency allows a deduction for most interest on money borrowed to earn investment income, such as interest or dividends, but not if the only possible return is a capital gain. Borrowing for your own renovation or personal spending is not deductible. Get an accountant’s advice before borrowing.
What happens if I only pay the interest on my HELOC?
The balance never goes down. Carrying $50,000 at 5.70% interest-only for five years costs about $14,250 in interest, and you still owe the full $50,000. Paying it off over five years instead costs about $960 a month and about $7,581 of interest in total, based on 2027 rate levels.
Is a HELOC or a refinance better in 2027?
A HELOC is usually better for smaller or staged amounts you will repay soon, since you pay interest only on what you draw. A refinance is usually better for a large lump sum carried for years, because mortgage rates tend to be lower than prime plus a spread, though breaking a mortgage early can cost a penalty.
Do I have to pay off my HELOC when I sell my house?
Yes. FCAC says you must repay your HELOC if you sell your home, because the line is secured against the property. If you sell in Ontario in 2027, plan for the full HELOC balance to come off your sale proceeds along with your mortgage and any discharge fees, and stop drawing on it once you list.

How this estimate is produced
The estimate blends recent selling prices for comparable units in the area with the details you entered: size, bedrooms, floor, exposure, parking, locker and condition. It is a statistical estimate, not an appraisal and not a formal opinion of value.
What it cannot see
- Interior condition and upgrades beyond what you told it
- Unit-specific issues: noise, an obstructed view, a pending special assessment
- Your reserve fund and where the maintenance fee is heading
- What is competing with you in your own building right now
What moves the number most
- Floor and exposure, which can separate otherwise identical units
- Parking and locker, each priced separately by buyers
- Kitchen and bathroom condition
- Maintenance fee per square foot against the rest of the building
Treat it as a range, not a price
A single figure to the dollar would be false precision. Use the estimate to decide whether a move is worth exploring. Before you price anything for the market, the number needs checking against what is actually selling and sitting in your building this month, and that takes a person. I will do that for you at no cost and with no obligation.
