How to Finance a Home Renovation in Ontario: HELOC, Refinance & More

Planning · 9 min read · 2025-09-15

A $120,000 renovation needs a financing plan, not just a contractor. This guide compares every major option available to Ontario homeowners — HELOCs, refinancing, purchase-plus-improvements, loans, and more — with honest pros and cons for each.

With whole-home renovations in the GTA routinely costing $180,000 or more, and even a single bathroom running $22,000+, very few homeowners pay for major renovations out of savings alone. How you finance the project affects your total cost as much as which contractor you hire — the difference between a HELOC at prime-plus and a high-interest personal loan can be tens of thousands of dollars over the life of the borrowing.

This guide walks through every major financing option available to Ontario homeowners in 2026, roughly in order of how favourable the borrowing costs tend to be, with the honest trade-offs of each. The right answer depends on your equity, your income, your timeline, and the size of your project.

HELOC: The Most Popular Renovation Financing Tool

A home equity line of credit is the workhorse of renovation financing in Ontario, and for good reason. HELOCs are typically priced at the lender's prime rate plus a margin (often prime plus 0.5% to 1%), which makes them far cheaper than unsecured borrowing. Combined with your mortgage, total borrowing is generally capped at 65% of your home's value for the revolving HELOC portion, or up to 80% when structured with an amortizing mortgage component.

The structural advantage of a HELOC for renovations is flexibility: you draw funds only as milestone payments come due, you pay interest only on what you have drawn, and you can pay it down and re-borrow without penalty. For a phased renovation — kitchen this year, basement next year — nothing else matches it. The main cautions: HELOC rates are variable and move with prime, interest-only minimum payments make it easy to carry the balance indefinitely, and setting one up requires an appraisal and legal work, so start the application before your renovation, not during it.

Mortgage Refinancing: Best for Large Projects

Refinancing means breaking or renewing your existing mortgage and borrowing up to 80% of your home's appraised value, taking the difference out as cash. For a major renovation — a $220,000 gut renovation of an Etobicoke bungalow, or an addition on a Mississauga detached — refinancing often produces the lowest all-in rate, since fixed mortgage rates are typically below HELOC rates.

The trade-offs are timing and cost. Breaking a fixed mortgage mid-term triggers a prepayment penalty that can run into the thousands (the greater of three months' interest or the interest rate differential), so refinancing works best at renewal time. You also restart or extend your amortization, and the borrowed amount is locked in upfront — less flexible than a HELOC if your renovation scope is still evolving. Many GTA homeowners land on a hybrid: refinance for the core budget, keep a small HELOC for overruns.

Purchase-Plus-Improvements: Renovating a Home You Are Buying

If you are buying a fixer-upper — say, a dated Scarborough bungalow you plan to renovate before moving in — a purchase-plus-improvements mortgage lets you fold renovation costs into your mortgage at purchase. The lender bases the mortgage on the post-renovation value, using contractor quotes you provide before closing.

The catch is the mechanics: the renovation funds are held back by the lender and released only after the work is completed and verified, which means you or your contractor must float the costs in the interim. The program also requires fixed quotes upfront and works best for defined-scope projects (a kitchen, flooring, a bathroom) rather than open-ended gut renovations where scope evolves. It remains one of the best tools for buyers priced out of renovated homes in the GTA, where the gap between renovated and unrenovated prices in neighbourhoods like East York can exceed $300,000.

Personal Loans, Lines of Credit, and Credit Cards

If you lack home equity — or the project is too small to justify HELOC setup costs — unsecured options fill the gap. An unsecured line of credit typically prices several points above prime and suits projects in the $12,000–$32,000 range. A fixed personal loan offers predictable payments over 1–5 years at higher rates still, which can suit borrowers who want forced discipline rather than a revolving balance.

Credit cards should only ever fund small projects — a $6,000 powder room refresh you can pay off within a statement cycle or a short promotional period. At standard rates of 20% or more, carrying renovation debt on a card is the most expensive mistake in home financing. If you find yourself planning to carry a five-figure card balance, stop and restructure the financing first.

A word on contractor-offered financing: some renovation companies offer in-house or third-party financing plans. Read these carefully. Rates are often higher than bank alternatives, promotional zero-interest periods can convert to very high rates retroactively if not paid in full, and financing tied to your contractor removes your leverage if the work goes badly. Never let financing convenience drive your contractor choice — vet the contractor and the financing separately.

Check Rebate and Incentive Programs Before You Start

If your renovation includes energy-efficiency upgrades — insulation, windows, heat pumps, air sealing — check the current federal and provincial rebate and low-interest loan programs before finalizing your scope and budget. These programs change frequently in name, funding, and eligibility, so verify what is active on the official Government of Canada and Ontario websites, and through your utility, rather than relying on older articles or contractor claims.

Two practical tips: most energy programs require a pre-retrofit energy audit before work begins — do the work first and you may forfeit eligibility entirely — and keep every receipt and document, since rebate claims are paperwork-heavy. Timed correctly, incentives can meaningfully offset the cost of mechanical and envelope upgrades on an older GTA home.
