Second Mortgage
A second mortgage is an additional loan registered behind an existing first mortgage, usually at a higher interest rate because it ranks second on title..
A second mortgage is an additional mortgage registered against a property that already has a first mortgage, and it ranks behind that first charge on title. Because the first lender is repaid first in a default or foreclosure, the second lender carries more risk and normally charges a higher interest rate.
How priority works on title
Mortgages are registered on title in order of priority. The first mortgage holds first rank and a second mortgage holds second rank. That ordering does not change because the second loan is large — it is registration order that decides who is paid first. If the property is sold, or the borrower defaults and a lender takes enforcement action, the first lender's balance is settled from the proceeds first, and the second lender is paid from whatever remains.
Borrowers use a second mortgage to fund a down payment on another property, consolidate high-interest debt, or cover a short-term cash need. Others prefer a home equity line of credit, which is revolving, or a full refinance that folds the extra amount into the first mortgage.
Why second mortgages cost more
Combined loan-to-value matters. A loan-to-value ratio measures total debt registered against the property's value, and because a second mortgage sits behind the first, the second lender's cushion is thinner. Pricing reflects that thinner cushion.
- Typically a higher rate than the first mortgage, often from a private or alternative lender.
- Often shorter terms, with fees that can include a lender fee and a broker fee.
- Separate enforcement rights — the second lender may act on default even while the first lender is patient.
Payments on a second mortgage are separate from the first mortgage payment. Missing them can trigger default and enforcement action, while unpaid property taxes or a rising first mortgage balance increase the pressure on the borrower.
Before you consider one
An exit strategy matters. Borrowers should plan how the second mortgage will be repaid — through a refinance, a sale, or lump-sum payments — and understand any prepayment penalty attached to it. Federally regulated lenders apply OSFI Guideline B-20 when underwriting, and second mortgages are also subject to provincial consumer protection rules. Confirm current terms and costs with a licensed mortgage professional before signing. Our guide to second mortgages and private lending in Canada explains how these products are structured.
Frequently asked questions
Is a second mortgage the same as a home equity line of credit?
No. A second mortgage is a closed, lump-sum loan registered in second position on title, repaid over a set term. A home equity line of credit is revolving: you draw, repay, and redraw up to a limit. Some lenders register a HELOC in second position, but the borrowing mechanics and payment structure differ.
Can I get a second mortgage if my first mortgage is with a bank?
Often yes, but the second lender must be able to register behind the existing first charge. Many banks allow a second mortgage from another lender; some charge a fee for consent or require notice. Approval depends on combined loan-to-value, credit, income, and the lender's own guidelines.
What happens to my second mortgage if I sell my home?
The second mortgage is paid out from the sale proceeds after the first mortgage and any other prior charges are discharged. If sale proceeds do not cover both balances, the shortfall can remain owing. Discharge fees may also apply, so confirm payoff figures before closing.
