Quick answer
How does a second mortgage work in Canada?
A second mortgage is a separate loan registered behind your first mortgage, letting you borrow against your equity without breaking your first mortgage. Most come from private lenders, credit unions, or B lenders, typically up to 75% to 85% combined loan-to-value, on 1 to 2 year terms at higher rates plus fees. Every second mortgage needs a clear exit plan.
What Is a Second Mortgage?
A second mortgage is a separate loan registered on your home behind your existing (first) mortgage. If the home is ever sold under power of sale, the first mortgage is paid in full before the second lender gets anything. That extra risk is why second mortgages cost more than first mortgages.
The main appeal: you can borrow against your equity without touching your first mortgage, its rate, or its term.
When Does a Second Mortgage Make Sense?
- Your first mortgage has a low rate and breaking it would trigger a large prepayment penalty
- You need money for a short period, for example to consolidate high-interest debt, fund a renovation, or cover a gap before a sale
- Your income or credit does not currently qualify for a refinance with a bank, but you have solid equity
- You are self-employed or recently had a credit event and need time to rebuild before refinancing
It is usually a bridge to something better, not a long-term solution.
Who Offers Second Mortgages?
The big banks rarely offer standalone second mortgages. Most come from three places:
| Lender type | Typical borrower | What to expect |
|---|---|---|
| Credit unions and some B lenders | Good credit, provable income | Lowest cost, stricter qualification |
| Private lenders and mortgage investment corporations (MICs) | Equity-rich, credit or income issues | Higher rates, lender and broker fees, short terms |
| Home equity lines of credit (HELOC) | Strong borrowers with an existing bank relationship | Can sit in second position at some lenders; capped at 65% of value on its own |
How Much Can You Borrow?
Lenders look at combined loan-to-value (CLTV): your first mortgage plus the second, divided by the home's appraised value.
Example (illustrative): home worth $700,000, first mortgage of $400,000.
- At a 75% CLTV limit: $525,000 total, so up to $125,000 as a second
- At an 80% CLTV limit: $560,000 total, so up to $160,000 as a second
Private lenders commonly cap CLTV between 75% and 85%, lower in smaller towns and rural areas where homes take longer to sell.
What Does a Second Mortgage Cost?
Expect costs well above a first mortgage:
- Interest rate: private seconds are typically priced several percentage points above first mortgage rates, and many are interest-only
- Lender fee: a percentage of the loan, charged at funding
- Broker fee: common on private deals, disclosed up front in writing
- Appraisal and legal fees, since the second is registered on title
- Term: usually 1 to 2 years, with renewal fees if you need more time
Always compare the total cost against the penalty to break your first mortgage. Sometimes a refinance with the penalty is still cheaper than a year or two of second-mortgage interest and fees.
The Exit Plan: The Most Important Part
Because most second mortgages are short and expensive, every one needs a clear way out before it is signed:
- Refinance into one new first mortgage at your first mortgage's maturity, when there is no penalty
- Sell the property, for example after a renovation
- Pay it off from a known future event, such as an inheritance or a bonus
- Rebuild credit or two years of self-employed income, then move to an A or B lender
A second mortgage without an exit plan often ends up renewed repeatedly, with fees each time.
Second Mortgage vs Refinance vs HELOC
The three most common ways to access home equity compared:
| Option | Best for | Main drawback |
|---|---|---|
| Refinance | Long-term needs; qualifies with an A lender | May trigger a prepayment penalty; capped at 80% LTV |
| HELOC | Flexible, ongoing borrowing; strong credit | Capped at 65% LTV on its own; variable rate |
| Second mortgage | Short-term needs; keeping a low first-mortgage rate | Higher rate and fees; needs an exit plan |
Frequently asked questions
What is a second mortgage in Canada?
A second mortgage is a loan registered on your home behind your existing first mortgage. It lets you borrow against your equity without breaking your first mortgage, but costs more because the second lender is paid only after the first lender if the home is sold.
How much can I borrow on a second mortgage?
Lenders limit the combined loan-to-value (first plus second mortgage divided by the home's value). Private lenders commonly allow 75% to 85% combined, with lower limits in smaller or rural markets.
Are second mortgage rates higher than first mortgage rates?
Yes. Because the second lender carries more risk, rates are typically several percentage points higher than first mortgages, and private second mortgages usually add lender and broker fees.
Can I get a second mortgage with bad credit?
Often, yes. Private lenders focus mainly on your equity and the property, so borrowers with bruised credit or hard-to-prove income can qualify if they have enough equity. The cost is higher, and a clear exit plan is essential.
Is a second mortgage better than breaking my mortgage?
It depends on the numbers. If the penalty to break your first mortgage is large and you only need the money for a year or two, a second mortgage is often cheaper. If you need the money long-term, refinancing is usually better even after the penalty.
