Mortgage Refinance in Ottawa: Costs, Rules and When It Pays Off

By the Ottawa Mortgages editorial team · Last reviewed: September 2026 · How we write our guides

What is a mortgage refinance? Refinancing replaces your current mortgage with a new one, usually with a new rate, term or amount. In Canada, you can typically borrow up to 80% of your home’s appraised value when refinancing, and you may pay a prepayment penalty and legal and appraisal costs to break your existing mortgage.

Homeowners in Ottawa refinance to lower their rate, pull out equity for renovations or investments, consolidate higher-interest debt, or change from a variable to a fixed rate. Whether it makes sense depends on your penalty, the new rate and how long you plan to stay.

Common reasons to refinance

  • Lower your interest rate if rates have dropped since you signed.
  • Access home equity for renovations, education or an investment.
  • Consolidate debt such as credit cards or lines of credit into a lower-rate mortgage.
  • Change your term or type, such as moving from variable to fixed.
  • Remove or add a person to the mortgage after a life change.

How much can you borrow when refinancing?

Federally regulated lenders allow you to refinance up to 80% of your home’s appraised value. For example, on a home valued at $700,000, the maximum mortgage would be $560,000. Your new mortgage must pay out your existing balance first, and you can take the rest as cash, subject to qualification.

What does it cost to refinance?

CostDetails
Prepayment penaltyVariable: usually three months of interest. Fixed: the greater of three months of interest or the interest rate differential (IRD).
AppraisalOften required to confirm your home’s value.
Legal feesA lawyer registers the new mortgage and discharges the old one.
Discharge feesYour current lender may charge an administrative fee.

Ask your lender for the exact penalty in writing. If the penalty is large, it may be cheaper to wait until renewal, unless you have a strong reason to refinance now. A mortgage broker can compare the total cost of switching against staying.

Frequently asked questions

How much equity can I take out of my Ottawa home?

Up to 80% of your home’s appraised value, minus your existing mortgage balance, subject to income and credit qualification.

Does refinancing hurt my credit?

There is a credit inquiry when you apply, which can lower your score slightly and temporarily. Paying off debts with the proceeds can improve your credit over time.

Is it worth breaking my mortgage to get a lower rate?

Only if the interest you save over your remaining term is greater than the penalty and fees. A broker or lender can help you run this calculation.

Do I need to pass the stress test to refinance?

Generally yes. A refinance is treated like a new mortgage, so you must qualify at the stress-test rate.

How long does a refinance take?

Often two to four weeks, depending on the appraisal, documents and lawyer scheduling.
