# Reverse Mortgages Rarely Beat Doing the Math on a HELOC in Ottawa
A 68-year-old in Kanata refinanced into a reverse mortgage in 2019. The house was worth $620,000. She needed $35,000 to cover property tax arrears and some overdue maintenance, plus another $800 a month to close the gap between her CPP, OAS, and what it actually cost to live. The product did exactly what it promised. No monthly payments. No credit check. Money in the account within three weeks.
What she didn't map out was the cost over time. By 2024 the balance had grown to $87,000. That's $35,000 drawn up front, $48,000 in monthly advances, and $4,000 in interest compounded at 7.34% annually. The house is now worth $740,000, so plenty of equity remains. But $87,000 is what her two adult children won't inherit unless the house appreciates faster than 7.34% every single year she remains in it.
The pitch for reverse mortgages is correct on the surface. You can The Bank of Nova Scotia branch on Richmond Road still keeps pamphlets for reverse mortgages in the lobby. HomeEquity Bank's CHIP product. Equitable Bank's version. Both promise the same thing: cash flow without monthly payments, no credit check, money in your account inside a month. The pitch works because it answers the single question that keeps a 63-year-old homeowner in Barrhaven awake at night: how do I cover the gap between what I have coming in and what it costs to live here without selling the house?
The answer the industry gives you is technically accurate. You can access up to 55% of your home's value without making a payment for as long as you live there. The answer they don't lead with is what that access costs when you hold the product for fifteen years.
The compounding problem nobody shows you up front
Interest on a reverse mortgage currently runs between 6.23% and 6.39%, depending on the term and provider. That's meaningfully higher than a conventional five-year fixed mortgage in Ontario as of July 2026. The product adds that interest to the principal balance monthly, which means the debt compounds. At 7% annually, the loan balance doubles roughly every ten years. A $50,000 draw at age 65 becomes $100,000 at 75, $200,000 at 85, assuming you take no additional advances.
Now run that against Ottawa real estate appreciation. The ten-year average annual growth rate in the National Capital Region sits between 3% and 5%. Some years higher, some lower. The Kanata case in the opening is real: the homeowner drew $83,000 over five years, paid $4,000 in compounding interest, and now owes $87,000 against a house that gained $120,000 in value. The equity cushion held. But only because Ottawa's market stayed strong through 2019 to 2024. If appreciation had matched the long-term average instead of spiking, the race would have been much closer.
The question isn't whether you'll lose the house. The No Negative Equity Guarantee ensures you won't owe more than the fair market value when you sell. The question is how much equity survives for downsizing, assisted living, or heirs.
What a HELOC actually costs when you can afford the payment
A Home Equity Line of Credit charges interest only on what you draw, at a rate typically pegged to prime plus 0.5% to 1%. As of mid-2026, that puts HELOC rates in the 4.95% to 5.45% range, lower than reverse mortgage rates but with one structural difference: you pay the interest monthly, so the principal doesn't grow unless you draw more.
If you can cover $230 a month, a $50,000 HELOC at 5.45% keeps the balance flat. The same $50,000 in a reverse mortgage at 6.39% becomes approximately $68,000 after five years with zero draws beyond the initial advance. The HELOC requires qualifying, which means proving income or convincing the lender you can service the payment. Many retirees can't clear that bar, which is why the reverse mortgage exists.
But some can. A couple pulling $3,200 a month between CPP, OAS, and a small workplace pension might assume they don't qualify for anything with a payment. Run the stress test anyway. OSFI's mortgage qualification rule requires proving you can handle payments at the contract rate plus 200 basis points or 5.25%, whichever is higher. On a $50,000 HELOC, that's a stressed payment around $340 a month. If your budget has $350 of room and you can document it, some lenders will work with that, especially if the loan-to-value ratio is low.
The inheritance cost most families don't discuss until it's locked
The typical reverse mortgage conversation starts with "I don't want to burden my kids" and ends with "I didn't realize how much this would cost them." An $87,000 balance on a $740,000 house leaves $653,000 in equity, assuming the homeowner moves or passes tomorrow. If she stays another ten years and the debt doubles to $174,000 while the house grows at 4% annually to $1,095,000, the heirs receive $921,000. The reverse mortgage didn't bankrupt anyone. It did transfer $174,000 from the estate to the lender.
For a retiree with no children and no interest in leaving a legacy, that transfer is irrelevant. The goal is to exhaust the asset during their lifetime, and a reverse mortgage does that efficiently. For a retiree who assumes the kids will get most of the house and hasn't told them otherwise, the conversation that happens after the funeral is much harder than the one that should have happened before signing.
The alternative is deciding who the equity is actually for before you structure the draw. If it's for you, the reverse mortgage works. If some of it is meant to stay in the family, or if you might need a larger lump sum later for long-term care in Ottawa's private facilities, where monthly costs run $5,000 to $7,000, then locking in compounding debt early is the expensive path.
Reverse mortgages do what they promise. They just cost more than most people map out when they need the cash now and the math feels abstract.
