What Credit Score Do You Need for a Mortgage in Canada? (2026 Full Guide)

Your credit score for a mortgage in Canada is one of the most important factors in getting approved — but it is not the only factor, and a lower score does not mean homeownership is impossible. Whether you have a strong credit history, a few missed payments behind you, or you are just starting to build Canadian credit as a newcomer, there are lender options available at every credit level.

The minimum credit score needed for a mortgage in Canada depends on the type of lender you apply with. In 2026, A-lenders — Canada's major banks, credit unions, and monoline lenders — typically require a minimum of 680 for uninsured mortgages, and scores of 720 or higher unlock the most competitive rates. B-lenders and alternative lenders work with scores from 550 to 679. Private lenders have no set minimum.

Quick answer: The minimum credit score for a mortgage in Canada is 600 for CMHC-insured high-ratio mortgages at A-lenders, and 680+ for uninsured mortgages at the best rates. B-lenders accept scores from 550–679. Private lenders lend based on property equity with no score minimum but charge 8–14%+. Your credit score, income, down payment, and property type together determine your full range of options.

This guide covers the exact credit score thresholds by lender type, real rate and cost comparisons between tiers, and seven targeted steps to improve your credit score before you apply — so you enter the process informed, empowered, and in control.

Key Takeaways

• A-lenders (banks and federally regulated institutions) require a minimum credit score of 680 for uninsured mortgages — 600 for CMHC-insured high-ratio mortgages.
• B-lenders and alternative lenders accept credit scores from 550–679 at rates 0.50%–2.00% above A-lender levels.
• Private lenders have no set credit score minimum but charge 8–14%+ — a short-term bridge only.
• CMHC requires a minimum credit score of 600 for insured mortgage eligibility across all federally regulated lenders in Canada.
• On a $500,000 mortgage, an 80-point credit score improvement can save $2,500–$5,000 per year.
• A licensed Ontario mortgage broker shops all lender tiers simultaneously — no hard credit pull to start.

Credit Score Requirements by Lender Type in Canada (2026)

Credit score requirements for a mortgage in Canada work on a tiered system — different lender types use different minimums, and a higher score consistently unlocks lower rates and better terms.

Canadian credit scores are calculated by Equifax and TransUnion on a scale from 300 to 900. The following ranges represent how most mortgage lenders in Canada categorize borrower credit profiles:

• 760–900: Excellent — qualifies for the lowest A-lender rates available; strongest negotiating position
• 720–759: Very Good — strong approval odds at A-lenders; competitive rates across banks and monolines
• 680–719: Good — meets most A-lender minimums; slight rate premium above the top tier
• 600–679: Fair — eligible for CMHC-insured A-lender mortgages; B-lender territory for uninsured
• 550–599: Below Average — B-lender or alternative lender required; expect rates 1–2% above A-lender levels
• Below 550: Poor/Limited — private lender territory; rates 8–14%+; equity-based approval

Here is how the three lender tiers map to credit score ranges in 2026:

• A-lenders (Big Six banks, credit unions, monoline lenders): 680+ for uninsured conventional mortgages; 600 minimum for CMHC-insured high-ratio mortgages (less than 20% down)
• B-lenders / Alternative lenders (Equitable Bank, Home Trust, Bridgewater Bank, CMLS): 550–679 range; most require 20%+ down payment for lower scores; lender fees apply
• Private lenders (individual investors, Mortgage Investment Corporations): no set minimum; approval based primarily on property value, down payment, and exit strategy; rates 8–14%+

According to CMHC's mortgage insurance eligibility guidelines, for any high-ratio insured mortgage in Canada, the absolute minimum credit score accepted is 600. Below 600, CMHC, Sagen, and Canada Guaranty — the three authorized mortgage default insurers — will not insure the mortgage. This effectively blocks A-lender access for borrowers below 600 without 20% down.

OSFI context: All federally regulated lenders in Canada are required to follow OSFI Guideline B-20, which governs mortgage underwriting standards. Credit score is a key factor, but lenders also assess your gross debt service (GDS) ratio, total debt service (TDS) ratio, income documentation, and property type before making an approval decision.

Bottom line: Your credit score determines which tier of lenders can work with you — and directly affects the rate you will pay. In Ontario, a score below 680 does not disqualify you from homeownership. It means accessing a different lender type, likely requiring a larger down payment, and potentially following a short-term plan to move up to A-lender territory at renewal.

A-Lender Mortgages in Canada: What a 680+ Credit Score Unlocks

An A-lender mortgage means a mortgage from a federally regulated financial institution — and qualifying at this tier gives you access to Canada's lowest mortgage rates, the most flexible terms, and the strongest borrower protections.

A-lenders include Canada's Big Six banks (TD, RBC, BMO, CIBC, Scotiabank, National Bank), federally regulated credit unions, and monoline lenders (non-bank lenders who originate exclusively through mortgage brokers) such as First National, MCAP, and Street Capital. With a credit score of 680 or higher, you can shop this full market.

What a strong credit score unlocks at an A-lender:

• Best available 5-year fixed rates — in May 2026, top insured rates range from approximately 3.94% to 4.34% for well-qualified borrowers; uninsured rates from 4.19% to 4.59%
• Maximum amortization — up to 25 years for insured mortgages; up to 30 years for uninsured with sufficient equity and down payment
• Full prepayment privileges — typically 15–20% lump sum annually plus 15–20% payment increase option, penalty-free
• Portability — the ability to take your mortgage with you when you sell and buy a new property, avoiding break penalties
• Stress test qualification at the full B-20 qualifying rate — meaning more mortgage room relative to income than B or private tier

The rate impact of credit score within the A-lender tier:

Even within the A-lender tier, your credit score affects your rate. A borrower with a 760+ score typically receives the best advertised rate — the lender views them as lowest risk. A borrower at 680–719 may pay 0.10%–0.25% more, as the lender prices in slightly elevated risk. On a $500,000 mortgage over a 5-year term, a 0.20% rate premium costs approximately $5,000 in additional interest.

Ontario homebuyers across Scarborough, Richmond Hill, North York, and the wider GTA who improve their credit score from 660 to 720 before applying gain access to the full A-lender market — a change that can save tens of thousands over their mortgage lifetime.

Definition moment: A monoline lender (the technical term for a non-bank mortgage lender who originates exclusively through licensed brokers) often offers rates that are 0.10%–0.30% lower than the major banks' posted rates. This is one of the key advantages of working through an FSRA-licensed Ontario mortgage broker rather than going directly to a branch.

What the credit score mortgage Canada requirements mean for Ontario homebuyers in 2026: In Canada, the minimum credit score for an A-lender mortgage is 680 for uninsured (conventional) mortgages, and 600 for CMHC-insured high-ratio mortgages. These thresholds are established by CMHC guidelines and OSFI Guideline B-20. Borrowers with scores between 550 and 679 can access B-lender mortgages at rates typically 0.50%–2.00% above A-lender levels. Below 550, private lenders provide equity-based financing at 8–14%+ for short-term bridge situations. A licensed Ontario mortgage broker assesses your full profile — credit, income, down payment, property — across all lender tiers simultaneously.

B-Lender and Alternative Mortgages in Canada: Options for Credit Scores 550–679

B-lender mortgages in Canada are specifically designed for borrowers whose credit profile falls outside A-lender guidelines — including those with credit scores between 550 and 679, recent missed payments, non-traditional income documentation, or a past consumer proposal.

B-lenders (the technical term for Schedule II and Schedule III financial institutions and alternative mortgage subsidiaries) are still regulated lenders — but they use more flexible underwriting criteria than the Big Six banks. In Ontario, the most recognized B-lenders include Equitable Bank, Home Trust, Bridgewater Bank, and CMLS Financial.

What to expect from a B-lender mortgage in Ontario:

• Credit score range: typically 550–679, though some lenders go lower with compensating factors such as a large down payment or strong equity
• Rate premium: 0.50%–2.00% above equivalent A-lender rates — in May 2026, B-lender mortgage rates for this tier typically range from 5.19% to 6.49%
• Down payment: most B-lenders require a minimum of 20% for uninsured mortgages when the credit score is below 680; no CMHC insurance available for most B-lender products
• Lender fees: fees of 0.50%–1.50% of the mortgage amount are standard at B-lenders — factor these into your total cost calculation alongside the rate premium
• Terms: typically 1–2 year terms, with the expectation that the borrower improves their credit and refinances to an A-lender at renewal

Who uses B-lender mortgages in Ontario:

• Borrowers recovering from a period of missed payments, a consumer proposal, or recent credit damage
• Self-employed Canadians whose income is harder to document under standard A-lender guidelines
• Newcomers to Canada with limited Canadian credit history but strong income and savings
• Borrowers who recently changed employment or have variable commission-based income
• First-time buyers in the GTA with solid income but a short credit history that hasn't reached A-lender thresholds

A B-lender mortgage is not the destination — it is a stepping stone. A well-structured B-lender mortgage, combined with a deliberate credit improvement plan, can position you to refinance to an A-lender within 12–24 months. This transition strategy is one of the most common paths that lendsimpl brokers help Ontario clients navigate.

Real cost example: On a $450,000 mortgage, a B-lender rate of 5.79% vs. an A-lender rate of 4.39% adds roughly $330 more per month — or $3,960 per year. Whether that premium is worth accessing homeownership now rather than waiting depends on your local market, rental costs, and how quickly you can move back to A-lender territory.

Bottom line: A B-lender mortgage in Canada means paying more — but it can mean getting into a home now rather than waiting years to reach A-lender thresholds. With a 12–24 month plan to rebuild credit, the total extra cost is often less than continued renting in a market where prices have historically risen.

Private Mortgages in Canada: When Your Credit Score Is Below 550

Private mortgage lending in Canada is equity-based lending — meaning approval depends primarily on your property value, down payment amount, and exit plan, rather than your credit score.

Private lenders include individual investors, Mortgage Investment Corporations (MICs — the technical term for pooled mortgage investment funds), and lending syndicates that deploy their own capital outside the standard bank framework. In Ontario, all mortgage brokers and agents who arrange private mortgages must be licensed by FSRA (Financial Services Regulatory Authority of Ontario).

What private mortgages in Ontario look like in 2026:

• Interest rates: 8% to 14%+ depending on property location, LTV, borrower profile, and individual lender risk appetite
• Lender fees: 2%–4% of the mortgage amount, payable at closing
• Our services: an additional 1%–2% is standard on private transactions — full disclosure required under FSRA regulations
• Term: typically 1 year, renewable — not intended as permanent long-term financing
• LTV (loan-to-value): most private lenders in Ontario lend up to 65%–75% of the appraised property value
• Approval timeline: often 3–7 business days for a clean file — making private mortgages useful in time-sensitive situations

When does a private mortgage make sense despite the higher cost?

1. Emergency bridge financing — closing on a property purchase while waiting for A-lender or B-lender approval to come through
2. Recent serious credit event — bankruptcy, consumer proposal, or a large derogatory mark that disqualifies you from regulated lenders but that will clear within 12–24 months
3. Income documentation gap — strong equity and clear ability to repay, but income structure doesn't satisfy regulated lender requirements
4. Foreclosure prevention — purchasing time to sell a property or restructure debt while avoiding power of sale proceedings
5. Unique property type — a non-standard property that regulated lenders won't touch but a private lender will assess on LTV and equity

In the Toronto GTA market — including Scarborough, Pickering, Ajax, North York, and Brampton — private mortgages are used regularly because property values are high enough to satisfy the LTV requirements even on mid-range loan amounts.

Important: A private mortgage must always have a clear exit strategy — refinancing to a B-lender or A-lender within 1–2 years as your credit improves, or selling the property. Always work with an FSRA-licensed Ontario mortgage broker when arranging private financing. They are legally required to disclose all fees, ensure you understand the full cost, and protect your interests in the transaction.

7 Ways to Improve Your Credit Score Before Applying for a Mortgage in Canada

Improving your credit score before a mortgage application is one of the highest-return financial moves an Ontario homebuyer can make — because every improvement in your score means a lower rate, and a lower rate compounds into thousands of dollars saved over your mortgage term.

1. Pay every bill on time, every month. Payment history is the single largest component of your credit score — approximately 35% of your total score according to Equifax Canada. A single 30-day late payment can reduce your score by 50–100 points. Set up pre-authorized payments for all credit cards, utility bills, and any existing loans to ensure nothing falls through.
2. Keep credit card utilization below 30%. Credit utilization (the ratio of your credit card balance to your credit limit) accounts for roughly 30% of your credit score. If your card has a $5,000 limit and you are carrying $3,500, your utilization is 70% — which significantly suppresses your score. Pay balances down to below 30%, or request a limit increase to improve the ratio without paying down debt.
3. Do not close old credit accounts. The length of your credit history makes up approximately 15% of your credit score. Closing an old credit card reduces your average account age and also cuts your total available credit — both of which can hurt your score. Keep old accounts open and make small purchases on them occasionally to keep them active.
4. Avoid multiple hard credit inquiries before applying. Each time a lender formally pulls your credit (a hard inquiry), it can reduce your score by 5–10 points. In the 6 months before a mortgage application, avoid applying for new credit cards, car loans, or other credit products. Note: when a licensed mortgage broker shops your application across multiple lenders, most credit bureau models count this as a single inquiry within a 14–45 day window.
5. Review your credit report for errors — and dispute them. Both TransUnion Canada and Equifax Canada allow Canadians to access their credit report for free. Errors on credit reports are more common than most people realize: accounts that are not yours, incorrectly reported late payments, or balances that have been paid but still show as outstanding. Disputing and correcting these errors can improve your score meaningfully, sometimes within 30–60 days of the correction being made.
6. Add a small instalment loan to diversify your credit mix. Credit mix (the variety of credit types on your file) accounts for about 10% of your score. If your profile only contains credit cards, adding a small instalment loan — such as a car loan, secured personal loan, or a credit-builder loan offered by some Ontario credit unions — can improve your score by diversifying the types of credit you carry.
7. Be patient and plan ahead — credit improvement takes time. Negative marks from missed payments, collections, or a consumer proposal remain on your credit file for 6–7 years in Canada. Their impact diminishes over time with consistent positive activity, but there is no shortcut. If you have serious credit damage, a realistic 12–18 month rebuild plan — followed by a B-lender bridge mortgage, then refinancing to an A-lender — is the most practical path forward.

Ontario homebuyers in Richmond Hill, North York, Ottawa, Scarborough, and across the GTA who start a credit improvement plan 12–18 months before their target purchase date consistently qualify at higher credit tiers — saving significantly on their first mortgage rate.

Bottom line: You cannot dramatically change your credit score in a month. But consistent, targeted actions over 6–12 months can move a 640 score into the 700s — unlocking A-lender territory and saving thousands in mortgage interest. A licensed Ontario mortgage broker can review your current credit profile and tell you exactly what to focus on.

What options Ontario homebuyers can compare when their credit score affects mortgage qualification: The three main lender paths in Canada for mortgage applicants are A-lenders (minimum 680 for uninsured, 600 for CMHC-insured), B-lenders (550–679 range, rates 5%–7%), and private lenders (no minimum, equity-based, rates 8%–14%). Each path carries different rate premiums, down payment requirements, term lengths, and total costs. A licensed Ontario mortgage broker reviews your full profile — credit score, income, down payment, property type — and identifies which lender tiers are available to you and what the real total cost looks like across each path.

Does Getting Pre-Approved for a Mortgage Hurt Your Credit Score?

Getting pre-approved for a mortgage in Canada may trigger a hard credit inquiry — but the impact is smaller than most people fear, and understanding exactly how it works removes one of the most common concerns first-time buyers have.

The difference between a soft check and a hard pull:

A soft credit check (the technical term for a credit inquiry that does not affect your score) is used when a broker or lender reviews your credit during an initial consultation or general eligibility assessment. Soft checks are invisible to other lenders — they do not appear on your credit report as a formal query and have zero impact on your score.

A hard credit pull (also called a hard inquiry) is a formal credit check that lenders submit to the bureau when you formally apply for credit. A single hard inquiry typically reduces your credit score by 5–10 points — a small, temporary reduction that usually recovers fully within 3–6 months.

How mortgage pre-approval inquiries work in Canada:

• A formal pre-approval application triggers a hard pull submitted to Equifax or TransUnion
• A single mortgage hard pull typically reduces your score by approximately 5–10 points
• Credit bureaus in Canada apply a rate-shopping grouping window: multiple mortgage hard inquiries within a 14–45 day period are typically counted as a single inquiry — minimizing the total score impact of shopping across several lenders
• The score reduction from a hard pull is temporary and typically recovers within 3–6 months of continued normal credit activity

What lendsimpl does differently:

lendsimpl's initial mortgage consultation starts with a soft check only — no hard pull is triggered until you formally decide to proceed with an application. This means you can understand your options, compare lender scenarios across A-lenders, B-lenders, and private lenders, and get a clear picture of where you stand — all without any score impact. A licensed Ontario mortgage broker (FSRA #13763) will always explain what type of credit check is happening, and when, before it occurs.

For buyers in Toronto, Scarborough, North York, Pickering, and Ajax who are still deciding whether and when to apply, a soft-check consultation gives you a complete picture of your options and rate range without any downside.

5 common mistakes to avoid before a mortgage application:

1. Applying for a new credit card or car loan in the 6 months before your mortgage application — each hard pull reduces your score
2. Closing old credit accounts to 'clean up' your credit — this reduces your average credit age and hurts your score
3. Maxing out credit cards even if you pay them in full monthly — your score is evaluated at the statement date, not after payment
4. Missing a single payment because you assumed it would auto-pay — one 30-day late mark can drop a 720 score to 650 overnight
5. Assuming your score is the same across Equifax and TransUnion — lenders may pull from one or both bureaus, and the scores often differ by 10–30 points

When speaking with a licensed Ontario mortgage brokerage helps with credit score and mortgage qualification: A licensed Ontario mortgage broker can assess your credit score, income, down payment, and property goals across all lender tiers in a single consultation. lendsimpl (FSRA #13763) starts every assessment with a soft credit check — no score impact, no obligation. This gives Ontario homebuyers across Toronto, Scarborough, Richmond Hill, North York, Pickering, and Ajax a clear picture of which lenders will work with them today, what rate range to expect, and what practical steps would strengthen their application. Approval always depends on income, equity, credit history, property type, lender criteria, and documentation.

Frequently Asked Questions: Credit Score and Mortgages in Canada

What is the minimum credit score needed for a mortgage in Canada?

The minimum credit score for a mortgage in Canada depends on the lender type. For CMHC-insured high-ratio mortgages (less than 20% down payment), CMHC requires a minimum credit score of 600. For uninsured conventional mortgages at A-lenders, 680 is the typical minimum. B-lenders work with scores from approximately 550 to 679. Private lenders have no set minimum and approve based on property equity and exit strategy. The right threshold for your application depends on your down payment amount, income, and which lender type can best serve your situation.

Can I get a mortgage in Canada with a credit score of 600?

Yes — a credit score of 600 can qualify for a CMHC-insured mortgage from an A-lender in Canada, provided your income, down payment (minimum 5%), and debt ratios meet OSFI Guideline B-20 requirements. However, 600 is the minimum threshold, and any other weakness in your application — high GDS or TDS ratio, variable income, thin credit file — may push you to B-lender territory instead. A score of 620–660 meaningfully improves your options. A licensed Ontario mortgage broker can assess your full profile and advise on the most realistic lender path for your specific file.

What is a B-lender mortgage and how is it different from a bank mortgage?

A B-lender mortgage (the technical term for a mortgage from an alternative or non-prime lending institution) is designed for borrowers who do not fully meet A-lender guidelines due to credit score, income documentation complexity, or recent credit events. B-lenders such as Equitable Bank, Home Trust, and Bridgewater Bank are still regulated — but they use more flexible underwriting criteria. The trade-off is higher rates (typically 1–2% above bank rates), lender fees at closing, and shorter terms of 1–2 years. Many Ontario homeowners use B-lenders as a planned bridge to A-lender qualification.

Does getting a mortgage pre-approval hurt my credit score in Canada?

A formal mortgage pre-approval triggers a hard credit inquiry, which typically reduces your credit score by 5–10 points temporarily. However, if you shop across multiple lenders within a 14–45 day window, credit bureaus typically group these as a single inquiry — minimizing the total impact. lendsimpl starts every initial consultation with a soft check only, so there is no score impact during the assessment phase. A hard pull only occurs when you formally proceed with a specific lender application. The reduction from a hard pull typically recovers fully within 3–6 months of normal credit activity.

How long does it take to improve my credit score enough for a mortgage?

Most borrowers see meaningful credit score improvement within 6 to 12 months of focused effort. The fastest gains come from paying down high credit card balances (reducing utilization ratio) and ensuring all bills are paid on time going forward. Moving from a score of 620 to 680 — the key A-lender threshold — is achievable in under a year for most borrowers with consistent on-time payments and no new derogatory activity. For more serious credit damage such as a consumer proposal or bankruptcy, the recovery timeline is typically 2–4 years. A licensed Ontario mortgage broker can review your credit file and give you a realistic, personalized estimate.

What should I do if I have bad credit and want a mortgage in Ontario?

If you have bad credit and want a mortgage in Ontario, your best first step is to consult a licensed FSRA-regulated Ontario mortgage broker — not a bank branch. A broker can assess your full credit file, identify which lender tiers are currently available to you (B-lender or private), and build a realistic improvement plan with specific timelines. Options include: a B-lender mortgage now as a bridge to A-lender status; a private mortgage for urgent situations with severe credit damage; or a structured 12–18 month credit improvement plan before you formally apply. lendsimpl (FSRA #13763) provides this assessment with no obligation and no hard credit pull.
