Ontario mortgage enforcement follows legal rules and the terms of the mortgage. Once a borrower receives a notice or lawyer correspondence, the exact document matters. A broker should not interpret legal rights in place of counsel; the financing job is to determine what capital is required, how quickly it can be delivered and whether using it creates a better economic outcome than the alternatives.
The borrower may still have several strategic paths: cure the default, refinance the existing mortgage, use a second-position loan to pay arrears, sell voluntarily before a forced sale, or in some cases negotiate time while a transaction closes. Which path is rational depends on how much equity survives after all payouts and transaction costs.
The most dangerous assumption is that 'there is equity, so a private lender will solve it.' A lender can advance money and still leave the borrower unable to refinance or sell before the private term expires. We therefore model the exit at the same time as the rescue.
