When does it make sense to refinance a mortgage in Canada?

Refinancing makes sense when you can save significantly on interest (typically 0.5%+ rate reduction with 2+ years remaining), need to consolidate high-interest debt, want to access home equity for renovations or investments, need to change your mortgage terms (amortization, payment frequency), or need to remove or add someone from the mortgage after a life change like divorce.

How much does it cost to refinance a mortgage in Canada?

Typical refinancing costs include: prepayment penalty ($2,000–$25,000+ depending on mortgage type and rate differential), legal fees ($1,000–$2,000), appraisal fee ($300–$500), title search and insurance ($250–$400), and discharge fee from your current lender ($200–$350). Total costs typically range from $4,000–$30,000.

Can I refinance my mortgage before the term is up?

Yes, you can refinance at any time, but you will pay a prepayment penalty if you break your current term early. Variable-rate penalties are typically 3 months interest. Fixed-rate penalties are the greater of 3 months interest or the Interest Rate Differential (IRD), which can be significantly higher.

Is it better to refinance or wait for renewal?

If your mortgage renewal is within 6–12 months, waiting is usually better — you avoid the penalty entirely and can shop freely for rates. If you have 2+ years remaining and the rate savings significantly exceed the penalty, refinancing now saves money over the long run. Use the break-even calculation to decide.

Can I refinance to consolidate debt?

Yes. By refinancing for more than your current mortgage balance, you can use the extra funds to pay off credit cards, car loans, or other high-interest debt. Your mortgage rate (4%–5%) is much lower than credit card rates (20%+). However, you are converting short-term unsecured debt into long-term secured debt against your home, so discipline is essential to avoid re-accumulating debt.

How much equity do I need to refinance?

You need at least 20% equity in your home to refinance. Lenders will not refinance above 80% loan-to-value (LTV). If your home is worth $600,000, the maximum refinanced mortgage is $480,000. Any existing mortgage balance must be below this threshold for you to access additional equity.

When Should I Refinance My Mortgage in Canada? (2026 Decision Framework)

Refinancing replaces your current mortgage with a new one — typically to get a lower rate, access equity, or restructure your debt. It’s not always the right move: timing, costs, and your specific financial situation determine whether refinancing saves you money or costs you more. This framework helps you decide.

The five reasons to refinance

Reason	When It Makes Sense	When It Doesn’t
Lower interest rate	Rate drop of 0.5%+ with 2+ years remaining on term	Small rate change or renewal is close
Debt consolidation	High-interest debt (credit cards/loans) exceeding $10,000+	If you’ll re-accumulate the debt
Access home equity	Renovations, investment, or major expense	If you don’t need the funds urgently
Change mortgage terms	Switch from variable to fixed (or vice versa), extend amortization	If your current terms are working fine
Life changes	Divorce (remove spouse), add partner, estate settlement	If simpler alternatives exist (blend and extend, assumption)

Reason 1: Refinancing for a lower rate

This is the most common reason. The calculation is straightforward: do your interest savings exceed the penalty and fees?

Decision framework

Question	If Yes	If No
Is the rate difference 0.5%+?	Continue evaluation	Probably not worth it
Do you have 2+ years left on your term?	Continue evaluation	Wait for renewal
Is the break-even under 24 months?	Refinance	Consider blend and extend
Is this a variable-rate mortgage?	Penalty is low (3 months interest) — often worth it	Calculate IRD carefully

Example: Rate refinance calculation

Detail	Current	After Refinance
Mortgage balance	$420,000	$420,000
Rate	5.40%	4.10%
Monthly payment	$2,547	$2,212
Monthly savings	—	$335
Prepayment penalty	—	$12,500 (IRD)
Legal fees	—	$1,200
Appraisal + discharge	—	$700
Total cost	—	$14,400
Break-even	—	43 months

At 43 months, this refinance is marginal on a 5-year term. If you had a variable rate with a $5,250 penalty, the break-even drops to 21 months — much more attractive.

Reason 2: Debt consolidation

Rolling high-interest debt into your mortgage can dramatically reduce your monthly payments and total interest cost.

Example: Debt consolidation

Debt	Balance	Rate	Monthly Payment
Credit card 1	$15,000	20.99%	$450
Credit card 2	$8,000	19.99%	$240
Car loan	$22,000	7.49%	$435
Total non-mortgage debt	$45,000	—	$1,125/month

After consolidation into mortgage at 4.25% over 25 years:

Detail	Before	After
Mortgage payment	$2,200	$2,450
Other debt payments	$1,125	$0
Total monthly payments	$3,325	$2,450
Monthly savings	—	$875

Warning: You’re converting unsecured debt (credit cards) into secured debt (your home). If you can’t make payments, you risk losing your home. Only consolidate if you address the spending habits that created the debt.

Requirements

Requirement	Details
Minimum equity	20% after refinance (80% max LTV)
Example	Home worth $600K: max mortgage $480K. If current mortgage is $400K, you can access $80K
Re-qualification	Must pass the stress test at the current qualifying rate
Appraisal	Required to confirm current home value

Reason 3: Access home equity

Use	Typical Amount	Consideration
Home renovations	$25,000–$150,000	Renovations that increase property value can offset the borrowing cost
Investment	Varies	Tax-deductible if used for income-producing investments (Smith Manoeuvre)
Education	$20,000–$80,000	Government student loans often have better terms
Emergency fund	$10,000–$50,000	A HELOC may be more flexible than refinancing
Business startup	Varies	High risk — consider carefully before pledging your home

Refinancing vs HELOC for equity access:

Factor	Refinance	HELOC
Rate	Fixed or variable (lower)	Variable (prime + 0.5%–1.0%)
Payment structure	Blended principal + interest	Interest-only minimum
Flexibility	One-time lump sum	Revolving credit line
Rate certainty	Can lock in fixed	Rate fluctuates with prime
Best for	Large one-time expense	Ongoing or uncertain amounts

→ See: HELOC vs Refinancing

Reason 4: Changing mortgage terms

Change	Why	Impact
Variable to fixed	Lock in certainty if rates may rise	Higher rate but predictable payments
Fixed to variable	Rates are falling and you want to benefit	Lower payments but rate risk
Extend amortization	Lower monthly payments	More total interest over the life of the mortgage
Shorten amortization	Pay off mortgage faster	Higher payments but significant interest savings
Change payment frequency	Switch to accelerated bi-weekly	Equivalent of one extra monthly payment per year

Reason 5: Life changes

Situation	What Refinancing Does
Divorce	Removes ex-spouse from the mortgage; one partner takes full ownership
Adding a partner	Adds new partner to the title and mortgage
Inherited property	Replaces existing mortgage with one in beneficiary’s name
Selling and buying simultaneously	May be combined with porting, bridge financing, or a new mortgage

→ See: Mortgage After Divorce

The full cost of refinancing

Cost	Amount	Notes
Prepayment penalty	$2,000–$25,000+	Variable = 3 months interest; Fixed = greater of 3 months or IRD
Legal fees	$1,000–$2,000	Some lenders cover this for switches
Appraisal	$300–$500	Required if accessing equity or switching lenders
Title search and insurance	$250–$400	Standard closing cost
Discharge fee	$200–$350	Charged by your current lender
Registration fee	$50–$100	Land registry fee
Total typical range	$4,000–$30,000	Depends heavily on penalty type

When to refinance vs alternatives

Situation	Best Option
Rate drop with 2+ years left, low penalty	Refinance
Rate drop with 2+ years left, high IRD penalty	Blend and extend
Renewal within 6–12 months	Wait for renewal
Need to access equity	Refinance (lump sum) or HELOC (revolving)
Consolidating small debt (<$10K)	Personal line of credit may be simpler
Consolidating large debt (>$25K)	Refinance
Switching variable to fixed mid-term	Blend and extend or refinance (penalty is only 3 months)
Divorce	Refinance (required to change title and mortgage)
