How does a second mortgage work in Canada? Rates, fees and the exit plan
A second mortgage sits behind your first mortgage and lets you borrow against remaining equity without refinancing. Here's how ranking, limits, rates, fees and a realistic exit plan work in Canada.
A second mortgage is a separate loan secured on your home that ranks behind your first mortgage. FCAC says you may usually borrow up to 80% of your home's value minus what you already owe, and that second-mortgage rates are generally higher because the lender is in second position. You keep paying the first mortgage and add a second payment. Alternative and private second mortgages are typically short term — FSRA says plan an exit. 8Twelve arranges these with third-party lenders and does not fund them. OAC.
Key takeaways
- →A second mortgage is a separate charge on title behind your first mortgage; your first rate and term stay the same.
- →FCAC's equity guide: borrowing is generally up to 80% of value minus existing mortgage balances.
- →Rates are usually higher than a first mortgage because the second lender is paid after the first if the home is sold.
- →Expect fees — appraisal, legal, title, and often lender or brokerage fees on alternative or private deals.
- →Build the exit first. FSRA treats alternate/private mortgages as short-term products that need a plan to refinance, renew or sell.
Short answer: How does a second mortgage work? You take a second loan secured on the same home; it ranks behind your first mortgage, so you keep that first payment and add another [1]. Lenders look at remaining equity (often within FCAC's 80% illustration), income and credit. Rates and fees are usually higher than a first mortgage, and many second mortgages are short-term bridges that need a clear exit [1][3].
This pillar is for homeowners who need a lump sum — renovations, debt cleanup, a down payment gift, tax arrears or a bridge to renewal — without replacing their first mortgage. Start with our equity takeout options, then compare a HELOC if revolving credit fits better.
What a second mortgage is
FCAC describes a second mortgage as a second loan on your home with the same basic features as a mortgage. While you pay it off, you also continue paying the first mortgage. Interest rates are usually higher than on first mortgages because the loan is riskier for the lender [1].
On title, "second" means priority: if the property is sold under power of sale or foreclosure, the first mortgage is paid before the second. That priority is why pricing and qualification differ from a refinance that creates a new first charge.
A second mortgage is different from:
- a refinance, which replaces the first mortgage with a larger one [2]
- a HELOC, which is revolving credit generally capped at 65% of value [1][4]
- a home equity loan, which FCAC lists as a lump sum up to 80% of value on a fixed schedule [1]
How much can you borrow?
FCAC's worked example: on a $250,000 home you may usually borrow up to 80% ($200,000). If you owe $150,000 on the mortgage, about $50,000 of room remains [1].
Example (illustrative): home $850,000; first mortgage $520,000.
| Item | Amount |
|---|---|
| 80% of value | $680,000 |
| Minus first mortgage | $520,000 |
| Illustrative room | $160,000 |
FCAC describes the 80% pattern for home-equity borrowing; individual lenders set lower caps, credit overlays and property rules. Some private lenders, in our experience, consider higher combined LTVs at a higher cost. OAC.
Qualification usually also includes income, credit, property type and debt ratios. Banks and many federally regulated lenders apply a stress test on underwritten mortgages [5]. Alternative and private lenders may use different income tests but still underwrite the deal.

Rates, fees and payments
Rates. FCAC says second-mortgage rates are generally higher than first-mortgage rates [1]. In our experience, prime-linked or near-prime second charges price closer to first-mortgage territory for strong files, while private seconds often use higher rates and sometimes interest-only payments. We don't publish a single "market rate" here because it would invent a stat — ask for quotes on your file, OAC.
Fees you should expect to see disclosed:
| Fee type | Why it appears |
|---|---|
| Appraisal | Confirms lending value [1] |
| Legal / notary | Registers the second charge |
| Title search / title insurance | Protects lender and borrower [1] |
| Lender or brokerage fee | Common on alternative/private files; FSRA expects written disclosure [3] |
| Discharge fee (later) | When you pay out the second |
Payments. You will have two payments unless a future refinance rolls both into one. Some seconds amortize; some are interest-only for a short term [3]. Interest-only keeps the payment lower and the balance flatter — fine only with a dated exit.
Worked example: $75,000 for 18 months
Example: you borrow $75,000 as a second mortgage at an assumed 9.99% interest-only rate for 18 months, then refinance into your first mortgage at renewal.
| Item | Illustrative figure |
|---|---|
| Monthly interest | about $624 |
| Interest over 18 months | about $11,239 |
| Assumed lender/brokerage fee (3%) | $2,250 |
| Assumed legal + appraisal | $1,800 |
| Approx. cost to bridge 18 months | about $15,289 (plus the $75,000 principal still owed) |

Compare that path with leaving a HELOC drawn, or with breaking a first mortgage mid-term. Our second mortgage vs HELOC and debt consolidation second mortgage guides run related side-by-sides.
Who uses a second mortgage — and who shouldn't
Common fits (our experience + FCAC use-cases for equity borrowing): - Need cash mid-term without triggering a first-mortgage penalty [2] - HELOC room under 65% is too small for the project [1][4] - Short bridge to a known renewal or sale date [3] - Consolidate higher-interest unsecured debt when a refinance penalty is steep
Poor fits: - No realistic way to repay or refinance within the term [3] - Income that can't support two payments - Hoping a second mortgage "fixes" spending without a budget change — FCAC warns consolidation can fail if habits don't change [6]
Step by step with a broker
- Pull your mortgage statement — balance, rate, maturity date, prepayment rules [2].
- Estimate value and 80% room using FCAC's pattern, then get an appraisal when a lender requires it [1].
- Choose the purpose and term so the exit matches (renewal date is the usual finish line).
- Compare lender types — institutional second vs alternative/private — with every fee in writing [3].
- Review ranking and consent — some first-mortgage contracts have conditions about further charges; your lawyer or notary confirms registration.
- Sign only after Independent legal advice where required, especially on private deals [3].
- Diary the exit — refinance, renew, sale or HELOC replace — before the second matures.
Second mortgage vs the main alternatives
| Need | Often compare |
|---|---|
| Revolving draws | HELOC / HELOC vs refinance |
| One new first mortgage | Refinance or renew (break-even) |
| Debt payoff mid-term | Debt consolidation second mortgage |
| Exit from a private second | Private mortgage exit strategy |
Risks FSRA wants you to see
FSRA's alternate/private mortgage consumer page stresses higher cost, shorter terms, fees and the need to understand how you will repay [3]. A second mortgage puts your home at risk if payments stop — same as any mortgage. Read the cost of borrowing disclosure, ask what happens at maturity, and don't sign under pressure.
How a second mortgage works is straightforward: second ranking, separate payments, usually less cheap than a first mortgage, and best as a bridge with an exit. Map equity with the 80% pattern, price fees honestly, then decide against a HELOC or a refinance at renewal. Next step: equity takeout options or our private mortgage rates overview for cost context.
