How to Refinance Your Mortgage in Ontario 2026 · Step-by-Step

Mortgage rates dropped 175 basis points from their 2023 peak. If you locked in at 5%+, refinancing could save $300–$600/month. Here’s exactly how.

When Refinancing Makes Sense in 2026

Refinancing isn’t automatic. You need three things to align:

• Rate differential ≥ 0.5%–1%. Lower rates alone don’t justify legal fees ($1,200–$1,800) and appraisals ($400–$600).
• Prepayment penalty ≤ breakeven savings. If your penalty is $8,000 but you’ll save $10,000 over 3 years, refinance. If the penalty exceeds savings, wait.
• Time horizon ≥ 2 years. Shorter holds make penalties hard to recover.

As of January 2026, Bank of Canada overnight rate sits at 2.75%, and 5-year fixed mortgages average 4.24%–4.49% depending on lender and down payment. If you’re paying 5.5%+ and plan to stay 3+ years, the math usually works.

Step 1: Get Your Home’s Current Value

Lenders require a current appraisal or valuation to refinance. Before you pay $400–$600 for a formal appraisal, get a free marker.

Use InstantCalculator’s Letter of Opinion. Our free home value tool generates an estimate based on recent comparable sales in your postal code. This tells you:

• Whether your home’s equity has grown (→ better LTV, lower rates)
• Ballpark refinance capacity if you need cash out
• Whether an appraisal is worth ordering

A Letter of Opinion takes 5 minutes and costs $0. It’s not a legal appraisal, but it’s 85%+ accurate for Ontario single-family homes and condos built after 1990.

Step 2: Pull Your Mortgage Statement & Calculate Your Penalty

Your current lender charges either:

• Interest Rate Differential (IRD). The difference between your current rate and the lender’s current 5-year rate, multiplied by remaining balance and time left on term. Example: You’re at 5.5%, lender’s rate is 4.25%, balance $400k, 2 years left = (5.5% − 4.25%) × $400k × 2 = ~$10,000. More common with big banks.
• Three Months’ Interest (3MIH). Simpler: 3 months of interest on your balance. Usually $2,500–$4,500 for $400k–$600k mortgages. Common with monoline lenders.

Action: Call your current lender and ask for a refinance quote letter. It must state:

• Exact prepayment penalty amount
• Penalty calculation method (IRD or 3MIH)
• Valid for how many days (typically 30)

Write this down. You’ll need it in Step 4.

Step 3: Shop 3+ Lenders (Big Bank + Monoline + Broker)

Don’t refinance with your current lender without shopping. Rates vary by $100–$300/month across lenders for the same borrower.

The three-lender approach:

• Big Bank (RBC, TD, BMO, Scotiabank, CIBC). Higher rates (typically 4.49%–4.79% for 5-year fixed), but faster approvals (10–15 days). Good if you need speed.
• Monoline Lender (Merrgage, Tangerine, EQ Bank, Simplii). 0.2%–0.5% lower rates (4.19%–4.49%), but require longer decision timelines (20–25 days) and stricter documentation. Better rates, more hoops.
• Mortgage Broker. Access to 50+ lenders, including B-lenders and private options. Best rates for non-standard situations (recent job change, self-employed, lower credit). Paid by lender, not you.

What to compare: Not just rate. Request a rate hold letter with:

• Exact rate (%)
• Hold period (10, 30, 60 days)
• Estimated legal fees and appraisal costs (if required)
• Estimated closing timeline

Step 4: Lock in Your Rate & Get a Commitment Letter

Once you’ve chosen a lender, request a rate hold. Most lenders hold rates for 30 days at no cost. If you’re not ready to move in 30 days, some will extend to 60–120 days for 0.1%–0.25% premium.

What happens next:

• Lender orders appraisal (if not done yet). Cost: $400–$600.
• You submit documentation: recent pay stubs, notice of assessment, employment letter, proof of property taxes, current mortgage statement.
• Underwriter reviews file. Timeline: 5–10 business days.
• You receive a conditional commitment letter once credit, employment, and property value are confirmed.

The commitment letter must state:

• Final rate locked
• Advance funding date
• Terms and conditions (e.g., “subject to appraisal at ≥$X value”)

Step 5: Legal, Appraisal, and Funding

Appraisal (if not done). Lender’s appraiser visits your home, inspects condition, and compares to recent sales. Takes 7–10 days. If value is lower than expected, lender may reduce the refinance amount or ask you to add equity.

Legal work. Your lawyer or notary discharges the old mortgage and registers the new one. Cost: $1,200–$1,800 in Ontario. Lawyer also confirms title is clear, property taxes are current, and no liens exist.

Funding. Once legal work is registered and all conditions are met, lender advances funds to your lawyer. Your lawyer pays out the old mortgage, covers legal fees, and deposits net funds to your bank account. Timeline: 1–3 business days after discharge is registered.

Total timeline from start to finish: 25–45 days.

Common Refinance Mistakes That Cost $10K+

1. Not calculating IRD correctly.

Many borrowers underestimate their prepayment penalty. Ask your lender for the exact number in writing, not a rough estimate. A $2,000 underestimation wipes out 6+ months of savings.

2. Refinancing into the same lender without shopping.

Your current lender doesn’t have to match competitor rates. Switching to a monoline or broker often saves $150–$300/month on the same mortgage balance.

3. Refinancing without a break-even timeline.

If your total costs are $2,000 and monthly savings are $200, your break-even is 10 months. If you’re selling in 18 months, it works. If you’re unsure about staying, wait.

4. Doing a full appraisal before rate shopping.

Order appraisals only after you’ve locked in a rate with a lender. Different lenders have different appraisers, and you might pay twice.

5. Waiting for “the perfect rate.”

Rates change daily. A 0.25% difference is worth $50/month on a $400k mortgage. If you’ve waited 6 months expecting rates to drop further and they rise 0.5%, you’ve cost yourself thousands in lost savings.

Should You Refinance or Sell?

Refinancing reduces your payment but extends your debt timeline. If you’re considering a move within 3–5 years, selling might be smarter. We’ve written a full guide: Should I Sell My House in 2026? Use it to weigh both options.

FAQ: Mortgage Refinancing in Ontario

Q: Can I refinance if I have less than 20% equity?

A: Yes, but you’ll pay Mortgage Default Insurance (CMHC, Sagen, or Canada Guaranty). Typically 1.5%–4% of the mortgage amount, added to your balance. This raises your payment and is only worth it if rate savings exceed insurance costs. A mortgage broker can model both scenarios for you.

Q: What if my property value has dropped since I bought?

A: If your LTV (loan-to-value) is now >80%, you’ll need insurance. If >90%, refinancing becomes expensive. In some cases, waiting for market recovery is cheaper than refinancing with insurance today. Get a current valuation first (use InstantCalculator) to know where you stand.

Q: Can I refinance to cash out equity?

A: Yes. If your home is worth $600k and you owe $400k, you have $200k equity. You can refinance for up to $480k (80% LTV) and pocket $80k. This resets your amortization, so your payment may not drop despite lower rates. Run the numbers with a broker before committing.

Q: What’s a “blended rate” refinance?

A: Instead of breaking your mortgage early and paying a penalty, some lenders will blend your current rate with a lower rate for the remaining term. Example: 5.5% on $300k + 4.5% on new $100k funds = blended 5.1% rate. No penalty, but rates are higher than a full refinance. Use this only if your penalty is very high.

Q: How does refinancing affect my credit score?

A: A hard inquiry drops your score 5–10 points temporarily. Multiple inquiries within 14 days count as one (so shop rates in a short window). Refinancing itself doesn’t hurt, but new credit activity can ding your score for 3–6 months. This rarely blocks approval if you have solid payment history.

Q: What if rates rise before my refinance closes?

A: Your rate is locked via the commitment letter. If rates rise, you’re protected. Lender eats the loss, not you. This is why rate holds matter—lock in before you apply.
