HELOC Borrowing Capacity Calculator Canada (2026)

Use this calculator to estimate your maximum HELOC credit limit, current rate based on your credit profile, and what your monthly interest costs would look like at different draw levels. Enter your home value, remaining mortgage, credit score, and province to see results in seconds.

The limit is determined by OSFI’s B-20 guideline: your HELOC cannot exceed 65% of your home’s appraised value, minus your remaining mortgage. The rate estimate uses the current prime rate of 4.45% (June 2026) plus a lender spread based on credit score.

How the HELOC Limit Is Calculated

OSFI (Canada’s banking regulator) caps all HELOCs at 65% LTV. This is not the bank’s discretionary policy — it is federal regulation that applies to every lender under OSFI supervision.

Formula:

HELOC limit = (Home value × 0.65) − Remaining mortgage

Example: $700,000 home, $400,000 mortgage

• Maximum HELOC = ($700,000 × 0.65) − $400,000
• = $455,000 − $400,000
• = $55,000 maximum

If you have no mortgage (rare), the maximum HELOC is simply 65% of the appraised value.

Current HELOC Rates by Credit Score (June 2026)

All HELOC rates are variable, calculated as prime plus a lender-set spread.

Prime rate = 4.45% as of June 10, 2026. Rate cuts or hikes will shift these figures. Rates assume owner-occupied residential property; rental or investment properties carry a higher spread.

HELOC vs. Other Borrowing Options

When a HELOC Makes Sense — and When It Doesn’t

Use a HELOC when:

• You have 35%+ equity and a stable income
• You’re consolidating high-interest credit card or personal loan debt
• You need flexible access to funds (draw only what you need, pay interest only on what you draw)
• You’re managing a renovation in phases and don’t know the exact final cost

Consider an alternative when:

• You’re relying on the HELOC to fund day-to-day expenses — this signals deeper cash-flow issues
• You’ve already consolidated credit card debt once and re-accumulated it (consolidation with a HELOC didn’t fix the behaviour)
• Total unsecured debt exceeds $40,000–$50,000 and repayment within 5 years is not realistic — a consumer proposal addresses the principal, not just the rate
• Your income is variable or at risk (layoff, self-employment downturn) — HELOC draws secured by your home are not appropriate emergency financing unless you have high confidence in income continuity

Getting a HELOC in 2026

A mortgage broker can compare HELOC products from 50+ lenders, including banks, credit unions, and monoline lenders. Monoline lenders often offer the most competitive HELOC spreads but require re-qualifying if you want to increase the limit later. Major banks often bundle HELOCs with readvanceable mortgages (like TD’s FlexLine or RBC’s Homeline) that automatically increase your HELOC room as you pay down the mortgage.

The application requires: home appraisal, income documentation (NOA, T4s, pay stubs, business financials if self-employed), credit check, and a title search. Most approvals take 2–6 weeks.
