If you have built equity in your home, you have two powerful ways to access it without breaking your existing first mortgage: a second mortgage or a home equity line of credit (HELOC). Both are secured against your home — but they price, qualify, and behave very differently. Choosing the wrong product in 2026 can cost the average Canadian household $3,000 to $11,000 over a single term. This guide is built for homeowners who want a clear, broker-grade answer to "which one is right for me?" — under the current OSFI B-20 stress test, the $1.5M insurable mortgage cap, and the rate environment we are actually living in. What Is a Second Mortgage? A second mortgage is a fixed-term loan registered in second position behind your existing first mortgage. You receive a lump sum at closing and repay it over a defined term with fixed monthly payments. It is offered by A-lenders, B-lenders, and private mortgage lenders.

A HELOC is a revolving credit facility secured against your home, similar to a credit card with a limit set by your equity. You draw what you need, pay interest only on what is drawn, and re-borrow as you repay.

Tax Treatment in Canada Mortgage interest on your principal residence is not deductible — first mortgage, second mortgage, or HELOC. CRA traces the use of borrowed funds. If you can clearly show the funds were used to earn investment income, the interest may be deductible. Consult a CPA before claiming. Effect on Your First Mortgage A second mortgage sits behind your first on title. Your first mortgage rate, term, and payment are completely unchanged. This is the single biggest reason brokers recommend a second mortgage over a refinance when you hold a sub-4% first that still has years left. Bottom Line Choose a second mortgage when you need a defined lump sum, want fixed payments, or have credit challenges. Choose a HELOC when you want flexible, ongoing access at potentially lower rates and you have strong credit.

This is the OSFI guideline that institutional lenders follow. Use the blended rate calculator to see how a second mortgage affects your total cost of borrowing, or the mortgage calculator for payment scenarios. Can I get a second mortgage with bad credit? Yes. B-lenders work with scores from 500 and private lenders focus on equity. Rates are higher but approval is achievable with at least 20% equity. Is a second mortgage the same as a home equity loan? Functionally yes — both are fixed-rate, fixed-term loans secured behind the first mortgage. Will a second mortgage hurt my credit? A new tradeline causes a small short-term dip. If you use it to pay off credit cards, your utilization ratio drops sharply and your score typically rises within 60–90 days. How long does approval take? Private: 3–5 business days. B-lender: 1–2 weeks. A-lender: 2–4 weeks. Can I have both a second mortgage and a HELOC? Possible but uncommon. Combined LTV must stay within 80% and most lenders prefer one or the other. What happens if I default? The second mortgage holder can initiate power of sale, but the first mortgage gets paid first from proceeds. Always speak to a broker before defaulting — restructuring is almost always cheaper.
