Short answer
Ontario law requires notice to specified people with registered or protected interests, including the mortgagor and certain later interest holders. A second mortgage holder may respond to protect its security, so the borrower should expect every registered lender to become involved.
The urgent client problem
The homeowner focuses only on the first mortgage arrears and assumes the second lender, spouse, execution creditor or other registered party will remain outside the problem.
What the official rule says
Part III of the Mortgages Act identifies persons who must receive notice before a mortgagee exercises a power of sale. The purpose is to alert affected interests and give them the statutory opportunity to respond before the property is sold free of later interests.
What this rule does not guarantee
Receiving notice does not mean a later lender will advance more money or postpone enforcement. It may instead trigger default rights under that lender’s mortgage. Unregistered interests and service disputes require legal analysis.
A practical Ontario example
Illustration only: The first mortgage enters enforcement while a private second mortgage is current. Once the second lender receives notice, it may demand information, pay arrears to protect its position or begin its own remedies, increasing the amount required to stabilize the property.
Practical options to explore now
Order an up-to-date title search and prepare one debt map showing every mortgage, lien, writ, tax balance and legal cost. Negotiate from the total payout requirement rather than solving the first mortgage while overlooking the rest of title.
Before choosing a solution, confirm
- The exact default, maturity, notice and proposed-sale dates.
- Every mortgage, lien, tax balance, arrears amount and recoverable cost.
- Current realistic property value and conservative net sale proceeds.
- Whether the proposed financing cures the entire title problem.
- The exit from any alternative/B, MIC or private solution.
Rajiv’s broker perspective
The first question is not simply, “Who will lend?” It is, “How much time and equity are actually left, and which solution improves the client’s position after every cost?” Ontario law controls notices, liens and enforcement. Each lender separately decides its underwriting, cure, renewal and payout policy. I would compare the existing-lender remedy, A or alternative/B refinancing, an appropriately structured MIC or private bridge, and a controlled sale. The best option is the one that resolves the whole problem and has a credible next step—not the option with the fastest promise.
