Financing Your Home Addition in Toronto — 2026 Options
A home addition requires progressive cash outflows over many months as different trades and materials are paid at various project stages. The financing vehicle you choose needs to accommodate this phased spending pattern. In 2026, Toronto homeowners primarily use three mechanisms: Home Equity Lines of Credit (HELOCs), progress draw construction mortgages, and mortgage refinancing.
Home Equity Line of Credit (HELOC)
A HELOC is a revolving credit facility secured against the equity in your home. Equity is the current appraised market value minus your outstanding mortgage balance. Under Canadian banking regulations, you can borrow up to 65–80% of your home's appraised value (combined with your existing mortgage).
How it works: You draw funds as needed to pay contractors, pay interest only on the outstanding balance, and repay principal at your own pace. Interest is charged only on what you have drawn — not on the full credit limit.
2026 rates: HELOC rates are variable, tied to the Bank of Canada's overnight rate, which sets the prime rate at major banks. As of early 2026, the prime rate at RBC, TD, Scotiabank, and BMO sits at 4.45%. HELOC rates are typically offered at prime plus a small margin (e.g., prime + 0.5%).
Fixed-rate option: Major banks offer hybrid products (like the TD Home Equity FlexLine or RBC Homeline Plan) that let you convert a portion of your revolving balance into a fixed-rate term with structured repayment. This locks in a rate and gives you budget predictability for that portion.
Best for: Projects where you have sufficient existing equity and want flexible, pay-as-you-go access to funds.

Progress Draw Construction Mortgage
When the cost of your addition exceeds your available home equity — common with second-floor additions and custom builds — a construction mortgage is the standard solution.
Unlike a regular mortgage that advances a lump sum, a construction mortgage disburses funds in predetermined stages called "draws" as specific milestones are verified by the lender's appraiser.
How it works: The lender bases the total loan on the projected completion value of your home after the addition is built (not what it is worth today). During construction, you make interest-only payments on the funds advanced so far. After completion, the construction loan converts into a conventional mortgage.
Standard Draw Schedule
| Draw | Milestone | Cumulative Funds Released |
|---|---|---|
| Draw 1 | Permits issued, site excavated, foundation poured | ~15% |
| Draw 2 | Framing complete, roof shingled, windows installed | ~40% |
| Draw 3 | Plumbing, electrical, HVAC installed; drywall hung | 65–85% |
| Draw 4 | Finishes installed, final occupancy permit issued | 100% |
The lender sends an independent appraiser to your site before each draw to confirm the milestone has been reached.
Best for: Large additions where construction cost exceeds available home equity.

If you have substantial equity but need a lump sum rather than a revolving line, refinancing replaces your current mortgage with a larger one that absorbs the renovation cost. You can typically access up to 80% of your home's appraised value.
Key consideration: Breaking your mortgage before the end of its term triggers prepayment penalties. To avoid these, time your project to coincide with your mortgage renewal date (every 3–5 years in Canada). At renewal, you can increase your mortgage amount penalty-free.
Best for: Homeowners with significant equity who want a single, structured payment and can align the timing with their mortgage renewal.
Tips Before You Commit
- Talk to your bank or a mortgage broker early — before you start design work
- Get pre-approval so you know your budget ceiling
- Factor in closing costs and any increase in monthly payments
- If you have mortgage insurance through CMHC, its rules may affect how much equity you can access
