Refinance vs HELOC: Which One Should You Actually Use?

Short answer: if you need the whole amount now and you are going to keep it borrowed for years, a refinance is almost always cheaper. If you need the money in stages, or you might not need all of it, a home equity line of credit usually wins even though its rate is higher. The rate gap between the two is small right now. What actually decides it is whether you are buying money or buying the option to borrow money.

What each one actually is

A refinance means breaking your existing mortgage and writing a new, larger one. You take the difference in cash. It is a new loan with a new term, a new rate and a fresh approval. In Canada you can refinance up to 80 percent of your home's value, and a refinance is always uninsured, so you pay uninsured pricing.

A HELOC is a revolving line secured against your home. You get a limit, you draw what you want, you pay interest only on what is outstanding, and you can pay it back and redraw. A standalone HELOC is capped at 65 percent of your home's value. If you combine a HELOC with a mortgage, the two together still cannot exceed 80 percent, and under the current rules the readvanceable portion, the piece that automatically grows as you pay down principal, is capped at 65 percent.

The rate difference matters less than people expect. As of late August 2026 the Bank of Canada policy rate is 2.25 percent after six consecutive holds, prime sits at 4.45 percent, and a typical HELOC is quoted at prime plus a spread, often landing near 4.95 percent. Uninsured five year fixed money has been available around 4.39 percent. So we are talking about roughly half a percentage point.

A worked example

Say the house is worth $900,000, you owe $400,000, and you want $100,000 for a renovation. Both routes are available: $500,000 combined is 55.6 percent of value, comfortably inside both the 80 percent refinance ceiling and the 65 percent HELOC ceiling. A standalone HELOC here could go as high as $185,000, since 65 percent of $900,000 is $585,000 less the $400,000 you already owe.

Illustrative. Payments calculated on Canadian semi annual compounding at the rates shown. Rate inputs current as of August 25, 2026: Bank of Canada policy rate 2.25%, prime 4.45%. Your rate, penalty and fees will differ.

The number that usually decides it

Over five years the refinance costs $4,272 less in interest on that $100,000, and leaves you owing $12,364 less. Call it a $16,600 advantage. That sounds decisive until you remember the penalty.

If you break a fixed mortgage mid term, most lenders charge an interest rate differential, which is roughly the interest they expected to collect from you minus what they can earn relending the money at today's rates. On a $400,000 balance, that penalty can run into five figures. Variable mortgages usually cap the penalty at three months of interest, which is much smaller.

So the test is simple. Add your penalty and your closing costs. If that total is less than the interest and principal advantage above, refinance. If it is more, take the line. Ask your lender for the exact penalty figure in writing before you decide anything, because the difference between an estimate and the real number is often thousands of dollars.

What you are really paying for with a HELOC

That extra half point is the price of optionality, which is the value of being able to do something without being required to do it. A line you never draw costs you nothing. A refinance you did not need costs you interest from day one on the whole amount.

For a renovation this matters a lot. Say the kitchen quote is $100,000 but you will pay it out over fourteen months in five instalments. On a HELOC your average balance over that period might be $45,000, not $100,000. Half a point more on $45,000 is about $225 a year. The refinance's cheaper rate does not help you, because you are paying it on money that is sitting in your chequing account doing nothing.

Where the HELOC hurts

Interest only payments feel great and quietly do nothing. Five years of dutiful HELOC payments and you still owe every dollar you borrowed. That is not the product's fault, it is a design feature, but a lot of people treat the minimum payment as if it were amortizing debt and are surprised later. If you take the line, set your own repayment schedule and treat it as non negotiable.

The second issue is rate risk. HELOCs float with prime. Prime has been steady because the Bank of Canada has held at 2.25 percent through six consecutive meetings, with the next decision on September 2, 2026. But a one point move in prime adds $1,000 a year per $100,000 outstanding. A fixed refinance moves that risk to the lender for the length of your term. That is worth something, and how much it is worth depends on how well your household absorbs a surprise.

Qualifying for either one

Both go through the stress test. The minimum qualifying rate at federally regulated lenders is the greater of your contract rate plus two percent or 5.25 percent, unchanged as of January 29, 2026. A refinance is a fresh underwrite, so your current income, debts and credit all get looked at again. That surprises people who have been in their home for a decade and assume the approval is a formality.

One more thing that is easy to miss. Because refinances are always uninsured, you cannot access insured pricing, and if your existing mortgage is insured you generally lose that status when you refinance. If you bought with less than 20 percent down and have been enjoying insured rates, do the comparison on the whole mortgage, not just the new money.

Quick rules of thumb

• Lump sum, long horizon, and you are near renewal anyway: refinance. No penalty, cheaper rate, forced principal repayment.
• Staged spending, or a maybe: HELOC. You are buying flexibility and it is cheap flexibility.
• Mid term on a fixed mortgage with a large balance: get the penalty quote first. It often settles the question by itself.
• Consolidating higher rate debt: either works, and the discipline question matters more than the rate. A line you can redraw is a line you can redraw.
• Borrowing to invest or to buy a rental: the deductibility of interest depends on what the money is used for and how the borrowing is structured. Talk to your accountant before you draw, not after.

One counterpoint worth stating. Everything above assumes rates roughly hold. If prime falls meaningfully over your term, the floating HELOC gets cheaper and the fixed refinance looks worse in hindsight. If prime rises, the reverse. Nobody knows which, and anyone who tells you they do is guessing with confidence. That uncertainty is exactly why the structural questions, how much you need, when you need it, and how fast you intend to pay it back, should drive the decision rather than a forecast.

The right answer here depends on your penalty, your renewal date and how you actually plan to spend the money, and those three things are specific to you.
