Understanding Second Mortgages in Ontario
What is a Second Mortgage?
A second mortgage is a new mortgage registered behind your existing first mortgage. You keep your first mortgage in place with its current rate and terms, while the second mortgage provides additional funds secured by your home equity. The second mortgage is subordinate to the first in priority.
Common Use Cases
Renovations, debt consolidation, bridging short-term needs, business cash flow, education expenses, tax arrears (case-by-case). Second mortgages offer flexibility when refinancing your first mortgage isn't ideal or would incur significant penalties.
How It Differs
Refinance: Replaces your entire first mortgage (potential penalties).
HELOC: Revolving line of credit with monthly interest payments.
Second Mortgage: Sits behind your first; keeps existing first mortgage intact; fixed term with interest-only or amortizing payments.
Qualification Factors
Home equity, property type and location, income and credit profile, documentation quality, existing liens. All subject to lender guidelines and appraisal. Combined loan-to-value (LTV) is a key factor—most lenders allow 80-95% combined LTV depending on your situation.
When a Second Mortgage Fits
Second mortgages work well in specific situations where keeping your first mortgage intact makes financial sense.
Renovations or Additions
Access funds for kitchen, bathroom, or basement renovations without breaking your favourable first mortgage term.
- Keep your low first mortgage rate
- No refinance penalties
- Increase home value
Debt Consolidation
Consolidate high-interest credit cards, lines of credit, or other debts when refinancing isn't ideal right now.
- Lower overall interest costs
- Single monthly payment
- Improve cash flow
Bridge-Like Needs
Cover timing gaps ahead of a property sale, inheritance, or planned refinance at renewal.
- Short-term solution
- Flexible repayment
- Clear exit strategy
Self-Employed Cash Flow
Smooth seasonal income fluctuations or fund business growth while keeping your first mortgage intact.
- Business flexibility
- Preserve first mortgage
- Manageable payments
Tax Arrears or Time-Sensitive Obligations
Address CRA debt, property tax arrears, or other urgent financial obligations (case-by-case).
- Resolve urgent issues
- Avoid liens or legal action
- Structured repayment
Legal Basement Suite Investment
Fund the creation of a legal rental unit to generate additional income (Ontario regulations apply).
- Rental income potential
- Increase property value
- Long-term investment
Spousal Buyout Complexities
Navigate separation or divorce buyouts where keeping the first mortgage makes financial sense.
- Preserve existing mortgage
- Fair settlement
- Legal coordination
Short-Term Objective Before Refinance
Address immediate needs with a plan to refinance both mortgages into one at your first mortgage renewal.
- Immediate access to funds
- Planned consolidation
- Cost-effective timing

Real Ontario Scenarios
Mississauga Semi: Renovation Without Refinance
Sarah and Tom own a semi-detached home in Mississauga worth $850,000. Their first mortgage balance is $450,000 at 2.8% with 2 years remaining. They want $120,000 for a kitchen and bathroom renovation but don't want to break their low-rate first mortgage.
Solution: They take a 2-year interest-only second mortgage for $120,000. Monthly interest payments are manageable, and they plan to refinance both mortgages into one at their first mortgage renewal. This preserves their low rate now and gives them the funds they need for renovations that will increase their home's value.
Ottawa Townhome: Debt Consolidation Strategy
Michael has a townhome in Ottawa worth $600,000 with a $350,000 first mortgage. He has $45,000 in high-interest credit card and line of credit debt (averaging 18% interest). His credit score has dropped due to high utilization, making traditional refinancing difficult.
Solution: Michael secures a $50,000 second mortgage to consolidate all his debt. His combined LTV is 66%, well within lender guidelines. The second mortgage rate is higher than his first but much lower than his credit cards. He sets up automatic payments and focuses on rebuilding his credit over the next 2 years, with a plan to refinance into one mortgage when his credit improves.
Toronto Condo: Tax Arrears Resolution
Jennifer owns a condo in Toronto worth $550,000 with a $300,000 first mortgage. She fell behind on CRA payments during a business downturn and now owes $35,000 in tax arrears. The CRA has threatened a lien on her property.
Solution: Jennifer obtains a $40,000 second mortgage to pay off the CRA debt immediately, avoiding a lien and potential legal action. Her lawyer coordinates the payment directly to CRA at closing. She sets up a 1-year amortizing second mortgage with a plan to refinance both mortgages at her first mortgage renewal in 18 months, once her business cash flow stabilizes.
Risks & Costs: What You Need to Know
Typical Costs
- Appraisal: $300-$500 (paid directly to appraiser)
- Legal fees: $800-$1,500+ for registration and closing
- Lender fees: Potential setup or administration fees (varies by lender)
- Discharge costs: Legal fees when you pay off the second mortgage
- Prepayment charges: Possible penalties if you pay off a closed term early (typically 3 months' interest or IRD)
I'll provide a detailed cost breakdown during our consultation so you know exactly what to expect.
Key Risks to Consider
- Higher rates: Second mortgages typically have higher interest rates than first mortgages due to subordinate lien position
- Combined LTV constraints: Your total debt (first + second) is limited by lender guidelines, usually 80-95% of home value
- Repayment discipline: Interest-only payments require a clear plan to repay or refinance the principal at term end
- Exit strategy: You need a realistic plan (refinance, sale, or lump-sum payment) before the term expires
- Priority of liens: The second mortgage lender is paid after the first mortgage in case of default or sale
We'll discuss all risks openly and compare second mortgages with refinancing and HELOCs to ensure you choose the best option for your situation.
