Quick answer
The amount is lender- and file-specific, so it should be calculated from the property, equity or down payment, income, debts, and current lender policy. This is a common question for Ontario borrowers whose finances do not fit a standard bank application. In this case, the useful starting point is the reason a conventional application may not fit and which lender type is designed to assess that exact issue.
Equity is the central calculation
For this particular question, the lender looks at the total of the first mortgage, proposed second mortgage, and sometimes other secured claims relative to the property value.
Not all equity is borrowable
What changes the answer is that the lender may keep a safety margin based on property location, condition, loan size, and risk.
Use a realistic property value
A useful distinction is that an appraisal may be required, and the amount available is based on the lender-supported value rather than an online estimate.
What can improve the result
A second mortgage can provide short-term liquidity, but it adds another secured payment. The borrower needs a clear plan for how that balance will be reduced or refinanced.
Documents to have ready
- Current first-mortgage statement and maturity date
- Property tax status and any other registered secured debts
- A realistic property value or recent appraisal if available
- The exact amount needed, intended use of funds, and planned payoff or refinance date
