The HELOC Looks Like Free Money Until You Actually Use One
The average Canadian homeowner now has roughly $420,000 in home equity sitting on their balance sheet, up from about $260,000 a decade ago. That number shows up on bank statements and property valuations like stored value waiting to be tapped. The HELOC is the tool designed to tap it, and banks market it accordingly: revolving credit, draw what you need, pay interest only on what you use, flexibility for life's opportunities.
Then someone actually uses one.
How the structure works against the borrower
A HELOC is a revolving credit line secured against the equity in your home, typically capped at 65% of the property's appraised value minus your outstanding mortgage. Borrow $40,000, pay it back, borrow it again. Interest-only payments. No set amortization. That flexibility is the entire pitch.
It's also the trap.
Because interest-only payments mean the principal never moves. A homeowner who draws $50,000 for a renovation in 2019 and makes the minimum payment every month still owes $50,000 in 2025. At 7.2% (prime as of early 2025), that's $3,600 a year just to service the balance. That's not financing a project. That's renting money indefinitely.
The math only works if you treat the HELOC like a short-term bridge and attack the principal aggressively. Most people don't. They treat it like available liquidity, which means they use it when liquidity is already tight, to cover a shortfall, patch a gap, smooth over an income disruption. The very conditions that make a HELOC attractive are the ones that make it hardest to pay back.
When it genuinely makes sense
There are real use cases. A HELOC can bridge timing gaps: fund a down payment on a new property before the old one sells, cover a known short-term expense with a clear repayment plan, consolidate higher-interest consumer debt if the borrower has the discipline to close the credit cards afterward. It works for income-generating investments, buying a rental property, financing business inventory with a clear payback within six months, where the asset throws off enough cash flow to service and retire the draw.
The common thread in every legitimate use is a concrete exit plan. You know what the money is for, you know where the repayment is coming from, and you know the date by which the balance hits zero.
Contrast that with the way HELOCs actually get used. A 2022 Equifax study found that roughly 23% of HELOC holders in Canada were using the credit primarily for non-specific liquidity, not a named project or purchase, just available funds. That's the clearest signal that the tool is doing psychological work instead of financial work.
The tax treatment adds confusion
Interest on a HELOC is tax-deductible only if the borrowed funds are used to earn investment income. Borrow $60,000 to buy dividend-paying stocks in a taxable account, you can deduct the interest. Borrow $60,000 to renovate your kitchen, you can't. The line gets blurry fast, especially when funds move between accounts or get used for multiple purposes. The CRA's position is strict: the deduction follows the use of the funds, not the security.
That means most homeowners using a HELOC for lifestyle expenses, renovations, or debt consolidation are paying non-deductible interest at prime plus, which as of early 2025 sits above 7%. A $75,000 balance costs over $5,000 a year after tax. Compare that to the interest saved by paying off a credit card at 19.99%, and the HELOC wins. Compare it to simply not carrying the debt, and it doesn't.
The real cost is optionality
The subtler problem is what a HELOC does to future flexibility. Equity tapped is equity unavailable. A household that draws $100,000 in 2023 has $100,000 less room to maneuver if rates spike, income drops, or a better opportunity surfaces in 2026. The HELOC doesn't create liquidity. It just moves it forward in time and charges rent.
Treat it like a tool with a timer. Sharp use cases, clear exits. Anything else and it's just leverage you're paying to carry.
