Cash-Out Refinance vs. Second Mortgage: Which Is Cheaper in Ontario?

Home equity has grown fast across Toronto, Mississauga, Brampton, Hamilton, Kitchener, Cambridge, London, Oshawa, Pickering, Caledon and St. Thomas, and a lot of Ontario homeowners are sitting on far more of it than they realize. Once you decide to put that equity to work — debt consolidation, a renovation, tax arrears, or covering a shortfall — you’re usually choosing between two products: a cash-out refinance or a second mortgage. Both turn equity into cash, but the cost difference between them can be significant, and the cheaper option isn’t the same for every homeowner.

What Is a Cash-Out Refinance?

A cash-out refinance replaces your entire existing first mortgage with a new, larger one. You pay off the old mortgage, borrow more than you owed, and pocket the difference in cash. From that point on you have a single mortgage payment — but it’s calculated on your entire mortgage balance at whatever rate you qualify for today, not the rate you originally locked in.

That’s the catch for a lot of Ontario homeowners right now. If you locked in a low fixed rate a few years ago, refinancing means giving that rate up on your whole balance, not just the new portion you’re borrowing. You may also face a prepayment penalty for breaking your current mortgage early, plus new appraisal and legal fees.

What Is a Second Mortgage?

A second mortgage is a separate loan registered behind your existing first mortgage. Your original mortgage stays exactly as it is — same rate, same term, same lender. The second mortgage is a new, smaller loan secured against the remaining equity in your home.

Because it sits in second position, the lender takes on more risk, so the rate on the second mortgage itself is typically higher than a bank mortgage rate. Approval is also usually based more on your available equity than your credit score or income documentation, which is why second mortgages are common among self-employed homeowners, those with non-traditional income, or anyone who’s been declined by a bank.

Side-by-Side: What Actually Costs More

Cash-Out Refinance Second Mortgage
Affects your existing mortgage rate Yes — entire balance moves to new rate No — original mortgage untouched
Typical rate Prime/bank rates Higher (often 8–12% with private lenders)
Approval speed Days to a few weeks Often 24–72 hours with private lenders
Qualification Full income/credit re-underwriting Primarily equity-based
Prepayment penalty risk Yes, if breaking a term early No — first mortgage isn’t broken
Best suited for Homeowners near their renewal date or with a rate close to today’s Homeowners locked into a good rate who need cash fast

When a Cash-Out Refinance Makes Sense in Ontario

A refinance tends to be the cheaper option when your current mortgage rate isn’t much better than today’s rates, when you’re close to your renewal date anyway (so there’s little or no prepayment penalty), or when you’d rather simplify down to a single payment and lender relationship.

When a Second Mortgage Makes Sense in Ontario

A second mortgage is usually the lower-cost route when you’re sitting on a mortgage rate from a few years ago that’s meaningfully better than current rates — breaking it to refinance would cost you more in lost savings than the higher rate on a second mortgage. It also tends to make sense when you need funds quickly, when your income doesn’t fit a bank’s standard documentation (self-employed, commission-based), or when you’ve already been declined by your bank and are working against a timeline, including a power of sale timeline.

A Quick GTA Example

Say you own a $900,000 home in the GTA with $550,000 remaining on your mortgage at a 3.9% rate, and you need $100,000 for debt consolidation.

  • Refinance path: Your full $650,000 balance moves to today’s rate — meaning your original 3.9% is gone, replaced across the entire loan.
  • Second mortgage path: Your $550,000 stays at 3.9%. Only the new $100,000 is priced at a higher private rate.

In most cases where the gap between your locked-in rate and today’s rate is wide, keeping the first mortgage untouched and adding a smaller, higher-rate second mortgage costs less overall than moving your entire balance to a higher rate. This is illustrative only — actual costs depend on your specific rate, lender, and loan-to-value position, which is why running the numbers with a broker matters more than a rule of thumb.

Frequently Asked Questions

Does a second mortgage affect my credit score? Applying for a second mortgage involves a credit check like any other loan, but approval is weighted heavily toward home equity rather than credit score alone, so bruised or limited credit doesn’t automatically disqualify you.

Can I get a second mortgage with bad credit in Ontario? Yes. Alternative and private lenders in Ontario primarily assess the equity in your home and your ability to make payments, which is why second mortgages are accessible to homeowners banks have declined.

What happens if I fall behind on a second mortgage in Ontario? As with any mortgage registered against your property, missed payments can eventually lead to power of sale proceedings. A broker can help you structure realistic payments upfront and flag options if your situation changes.

How fast can I get approved for a second mortgage? With private and alternative lenders, approvals can come back within 24–72 hours when your equity and property details are straightforward, compared to several weeks for a full refinance.

Can I use both strategies over time? Yes. Many homeowners use a second mortgage as a short-term bridge, then refinance into a single mortgage once their existing term is up for renewal or their credit and income situation has improved.
