How Much Equity Can I Access From My Ontario Home?

Equity you own vs. equity you may be able to access

The equity you own is simple arithmetic: what your home is worth, minus everything currently secured against it. The equity you may be able to access is a smaller number, because lenders will not normally lend against the full value of a property.

As a general reference point, most conventional residential mortgage financing in Ontario is measured against 80% of a property's lending value. That figure is a starting reference, not an entitlement. Whether any amount is available to you depends on qualification, the property itself and the criteria of the lenders eligible for your circumstances.

The calculation I walk clients through

1. 01Estimate the property value. This is a working estimate until a lender orders or accepts a valuation.
2. 02Multiply that value by 80% to get the lending-value reference.
3. 03Subtract every balance already secured against the home — first mortgage, any second mortgage, and any line of credit registered on title.
4. 04If the result is a positive number, that is the theoretical room. If it is zero or negative, there is no conventional room at that valuation.

You can run this yourself on the home equity calculator. It stores nothing and sends nothing anywhere — it simply shows you the arithmetic.

Why the number on the calculator is not an approval

Room on paper is only the first of several tests. A lender also reviews whether the payment is supportable, how the property presents, and whether the file fits its own policy. The Financial Consumer Agency of Canada's guide to preparing for a mortgage is a good plain-language overview of what gets reviewed.

• Income and how it is documented, including whether it is salaried, hourly, commissioned or self-employed.
• Existing debt payments, because they compete with the proposed housing costs.
• Credit history and how obligations have been managed.
• The property: type, location, condition and marketability.
• Lender-specific policy, which varies more than most homeowners expect.

What moves the number

Property values change, and so do balances. If you have been paying down a mortgage for several years, the accessible figure today is likely different from the figure you calculated when you last looked. A line of credit with a zero balance may still occupy registered room on title, which surprises people regularly.

How to use this in practice

Run the estimate, then treat it as a conversation starter rather than a plan. If the number is meaningfully different from what you expected, that difference is usually worth understanding before you make any decisions that depend on it.
