Second Mortgage in Canada: What It Costs, When It Beats a Refinance and How You Get Out
A second mortgage is a loan registered behind your existing first charge, which is why it can be arranged without touching the first mortgage or paying a penalty to break it. Most lending reaches 80% to 85% of the property’s value including the first mortgage, terms are commonly one year, and payments are often interest-only. It is more expensive than a first mortgage by design: in second position the lender is paid only after the first is made whole, and the pricing reflects that.
Apply nowWhat "second position" actually means
Position is registration order on title, and it decides who gets paid in a forced sale. The first mortgage is satisfied in full before the second receives anything. A second behind a $500,000 first on a $900,000 home is relying on the $400,000 of value above that first charge — and on that value holding if the property has to be sold quickly.
That is the whole explanation for the rate. It is not a penalty for a weak borrower; it is the price of standing behind someone else in the queue. The same lender will price a first charge far more cheaply on the same property.
When a second beats a refinance
Four situations, and the first is the most common by a wide margin:
- Your first mortgage is cheap. Breaking a fixed term costs the greater of three months’ interest or the interest rate differential. On a mortgage taken at a low rate, the IRD on a large balance can exceed the entire cost of a second mortgage.
- Speed. A private or MIC second can close in days. An institutional refinance does not.
- The file will not pass an institutional lender. Bruised credit, self-employed income, arrears — the equity still supports a loan even where the income documentation does not.
- You only need the money briefly. Bridging to a sale, a renewal, or the end of a renovation.
What it costs, in full
The rate is not the cost. A complete picture includes every line below, and all of it must be disclosed to you in writing before you sign:
| Cost | What it is |
|---|---|
| Interest rate | Higher than a first charge, and higher again with private capital than with an alternative lender |
| Lender fee | A percentage of the advance, usually deducted from the funds rather than paid up front |
| Broker fee | Charged on alternative and private files, disclosed in writing |
| Legal fees | Both sides — the lender’s costs are normally yours to pay |
| Appraisal | Required; the advance is set against its value, not the price you believe |
| Renewal or discharge fees | At the end of the term, and worth asking about at the start |
Ask for the total cost of borrowing over the actual term, not the rate. On a one-year interest-only second, fees can be a substantial share of what you pay, and two offers at the same rate are often not the same deal.
Your broker and lender owe you that disclosure. In Ontario it is FSRA that supervises it, with equivalent regulators in each province.
The exit plan is the underwriting
A one-year interest-only loan has to be repaid or replaced in twelve months, and a lender who cannot see how is a lender who declines. Three exits are accepted routinely:
- Refinance both charges into one first mortgage once credit or income supports it — the most common plan, and the reason many seconds are arranged alongside a credit-repair timeline.
- Sell. Both charges are discharged on closing.
- Repay from a known event. A bonus, a maturing asset, a completed renovation that lifts the appraisal.
"I will renew it" is not an exit. Renewal is at the lender’s discretion and carries another fee. Go in with a plan and a date.
Second, HELOC or home equity loan
These overlap, and the names are used loosely across the market:
| Structure | Ceiling | Qualifying | |
|---|---|---|---|
| Second mortgage | Lump sum, often interest-only, 1–2 year term | 80–85% | Equity and exit led |
| HELOC | Revolving, interest-only on drawn balance | 65% standalone, 80% combined | Full institutional qualification |
| Home equity loan | Lump sum, amortizing | 80% (85% alternative) | Between the two |
If you qualify institutionally, a HELOC is almost always cheaper. A second mortgage is what you use when you do not, or when speed or an untouched first mortgage matters more than the rate. See also home equity loans and debt consolidation.

Common questions
How much can I borrow on a second mortgage in Canada?
Generally to 80% or 85% of the property value including your first mortgage. On a $900,000 home with a $500,000 first charge, 85% is $765,000 of total lending, leaving roughly $265,000 before fees and subject to the appraisal.
Why are second mortgage rates higher?
Because of position, not borrower quality. In a forced sale the first mortgage is paid in full before the second receives anything, so the second lender carries more risk on the same property and prices for it.
Is a second mortgage cheaper than refinancing?
Often, when your first mortgage is below current rates. Refinancing breaks the first charge and triggers the greater of three months’ interest or the interest rate differential on the whole balance, which can exceed the full cost of a smaller second mortgage.
Can I get a second mortgage with bad credit?
Usually yes. Alternative and MIC lenders weigh the equity and your exit plan more heavily than the credit score. The rate and fees are higher, and lenders will want to see how the loan gets repaid or replaced at the end of the term.
What happens at the end of a one-year second mortgage?
You repay it, replace it, or renew it at the lender’s discretion with another fee. Lenders expect a stated exit at the outset — typically refinancing both charges into one first mortgage, selling, or repaying from a known event.
What fees come with a second mortgage?
A lender fee, a broker fee on alternative and private deals, legal fees for both sides, an appraisal, and renewal or discharge fees at the end. Ask for the total cost of borrowing over the term rather than the rate alone — all of it must be disclosed to you in writing.
