What personal credit score do you need for a business loan in Canada?

Plan around 650. That is the practical working number for personal credit on a Canadian small-business loan: the Big Five banks typically want roughly 650–680, lenders delivering the Canada Small Business Financing Program (CSBFP) often prefer 650+, and BDC — while it publishes no strict cutoff — sees most approved borrowers in the mid-600s or higher, with scores below 600 significantly reducing the chances. Alternative lenders may go as low as roughly 550, at a price. Canadian scores from Equifax and TransUnion run on a 300–900 scale. This guide covers what each lender type actually checks in the owner's personal finances, and how that assessment is weighed against the business plan the lender reads alongside it.

What credit score does each type of Canadian lender want?

There is no single national threshold — each lender applies its own criteria — but the market clusters into four tiers:

Lender type	Practical personal-score expectation	Notes
Big Five banks	~650–680	Own underwriting criteria; strongest files get the best pricing (~prime + 1–3%)
CSBFP lenders (banks/credit unions)	Often 650+	The program publishes no minimum; the delivering lender sets its own bar
BDC	No published cutoff; mid-600s+ common	Below 600 significantly reduces chances; 24+ month businesses get more flexibility
Alternative/online lenders	Down to ~550	Materially higher rates; faster decisions

Two details matter more than the raw numbers. First, these are lender preferences, not program rules — the CSBFP itself sets no credit minimum, so the same file can be declined at one participating lender and approved at another. Second, the score is a gate, not the whole decision. Clearing 650 gets the rest of your file read; it does not get the loan approved. That is where the plan, the projections, and your broader personal finances take over.

Why do lenders check personal credit for a business loan at all?

Because for most small businesses, the owner is the credit risk. Canadian lenders underwrite small-business loans using the five Cs of credit — character, capacity, capital, collateral, and conditions — and the personal credit report is their primary evidence on the first and most heavily weighted C: character.

BDC's financing advisors state the logic plainly. In the words of Wesly Joseph, a BDC advisor on financing with weaker credit: "Whatever tendencies you have on the personal side, you usually bring them to the business side." A history of missed personal payments, maxed cards, or collections is read as a preview of how the business's obligations will be handled.

The same BDC guidance goes further: a good personal credit score is "the most critical requirement for loans under $350,000." That range covers the large majority of Canadian small-business borrowing — for context, the average CSBFP loan in the program's record 2024–25 year was about $294,000. If your ask is under $350,000, assume the personal credit report is the first document the underwriter forms a view on.

What personal finances do lenders check besides the score?

The score opens the assessment; the underwriter then works through your full personal financial position. Expect scrutiny of:

• Personal debt service. Lenders generally want a total debt service (TDS) ratio below roughly 40% — all personal debt obligations, including the housing costs, as a share of gross income — and a gross debt service (GDS) ratio below roughly 32% for housing costs alone. An owner stretched thin personally has no cushion to support the business through a slow quarter.
• Personal net worth statement. Assets, liabilities, and what is left over. This feeds the capital and collateral Cs: can you make a real equity injection, and is there anything behind the loan if it goes wrong?
• The source and size of your own money in the deal. A specific, documented owner contribution — savings, an asset sale, a documented gift — reads as commitment. Lenders finance risk you demonstrably share.
• Credit report detail, not just the number. Utilization on revolving credit, recent late payments, collections, and prior write-offs each tell their own story. Two owners with identical 660 scores can be read very differently depending on what produced the number.

None of this is unique to one institution. Statistics Canada's Survey on Financing and Growth of SMEs shows the system works for most applicants — 88.2% of SMEs had their largest debt-financing request fully or partially approved in 2023 — but the approval rate falls to 77% for micro-businesses versus 94% for mid-sized firms. The smaller the business, the more the decision leans on the owner personally, and the more these personal-finance checks decide the outcome.

How do lenders weigh personal credit against the business plan?

It depends almost entirely on two variables: loan size and operating history.

Under $350,000, or any startup: personal credit dominates. A business with no operating history has no financial statements to underwrite, so the lender substitutes the owner's record — personal credit, personal debt load, owner investment, and industry experience — plus the realism of the projections. This is precisely the segment the CSBFP exists to serve: 74.1% of CSBFP lending in 2024–25 went to businesses under one year old, and the program's 85% government guarantee is what lets a lender say yes to a file with no track record. The guarantee does not replace the credit check — the delivering lender still underwrites on its own criteria — but it widens the risk appetite for exactly the borrowers whose files are mostly personal.

24+ months of operating history: the business can carry weaker credit. Once there are real financial statements, lenders underwrite the whole business story. Demonstrated cash flow that services the proposed debt with margin — projections that clear a debt-service coverage ratio around 1.25× — can offset a personal score that would sink a startup application. The owner's credit still matters, but it becomes one input among several rather than the gate.

The practical implication runs both ways. A startup founder with an excellent plan and a 580 score has a plan problem the plan cannot solve — the credit repair has to come first. An established owner with a 630 score and two years of strong statements has a presentation problem: the file needs to lead with the cash flow evidence, because that is the strongest card in it. Understanding which file you have determines whether the plan or the credit history is what gets you declined.

Will you have to sign a personal guarantee — and can they take your house?

Almost certainly yes to the guarantee; the house depends on which loan you sign. Personal guarantees are near-universal in Canadian small-business lending: CFIB reported to the Competition Bureau that more than half of business owners who secured loans in the past three years pledged a personal guarantee, and one in four used their primary residence as security.

But the two main loan types treat guarantees very differently, and the difference is worth understanding before you sign anything.

On a CSBFP loan, the lender may take an unsecured personal guarantee up to the original amount of the loan disbursed — and the program requires that this guarantee cannot be secured by your personal assets. Your house is not pledged as collateral for a CSBFP personal guarantee. Note the correction to a figure that still circulates widely: there is no 25% cap on CSBFP personal guarantees. That limit is outdated, and articles still citing it understate the real exposure — you can be personally liable up to the full original loan amount. The protection the program actually gives you is the unsecured character of the guarantee, not a cap on its size. Corporate guarantees under the program are uncapped and may be secured.

On a conventional loan, the guarantee often runs to the full amount owing and is sometimes secured — a collateral mortgage on your home, or a pledge of specific personal assets. This is where the CFIB's one-in-four figure comes from. A secured guarantee means the lender can realize on the pledged asset in a default; an unsecured guarantee means the lender must sue on the covenant first.

The honest comparison: CSBFP borrowers can still lose personal assets — a judgment on an unsecured guarantee is enforceable — but they start from a structurally better position than a conventional borrower whose home is directly charged. If limiting personal exposure matters to you, ask every lender the same two questions in writing: what is the guarantee amount, and is it secured or unsecured?

Does business credit matter, or only personal?

For young and small businesses, personal credit does almost all the work. A business credit file — Equifax and Dun & Bradstreet commercial scores, supplier trade lines, the company's own borrowing history — takes time to build and carries little weight until the business has roughly 24 months of history and its own repayment record.

That said, building the business file early is cheap and worth doing: put utilities, insurance, and supplier accounts in the company's name, pay them on schedule, and use a business credit card rather than a personal one for company spending. By the time the business qualifies to be underwritten on its own statements, a clean commercial file reinforces the story — and it is one of the few levers that eventually reduces how much your personal score decides.

What if your credit score is in the mid-500s?

You have three realistic paths, and they are not mutually exclusive.

1. Repair before applying. If the timeline allows six to twelve months, this is the highest-return move: bring every account current, pay revolving balances down well below their limits, and dispute errors on both your Equifax and TransUnion files (the two bureaus often hold different data). Score movement from these actions is meaningful and fairly fast.
2. Strengthen everything the score is not. A larger owner cash injection, pledged collateral, a creditworthy co-signer or guarantor, and a written, documented explanation of past credit events (a divorce, a medical event, a prior business failure with lessons stated) all shift how an underwriter reads the same number. Lenders distinguish between chaotic credit and explained credit.
3. Match the lender to the file. Alternative and online lenders approve scores near 550 at materially higher rates — Statistics Canada's data puts average SME term-loan rates at 9% and business credit cards at 19%, and alternative lending prices above bank credit. Used deliberately, an alternative-lender facility is a bridge: twelve months of clean payments plus an improving personal score builds the record to refinance with a bank or BDC on better terms.

One caution that applies at every score level: disclose CRA arrears proactively. Undisclosed tax or payroll debt is one of the most common automatic declines in Canadian small-business lending, and it damages the file far more when the lender finds it than when you explain it.

The bottom line

Canadian business lenders read the owner before they read the business. Under $350,000 — and for any startup — the personal credit report is the single most influential document in the file: 650 is the practical bar at the banks and most CSBFP lenders, 600 is the realistic floor at BDC, and mid-500s means alternative lenders and a repair plan. Personal guarantees are the norm, so know the difference between the CSBFP's unsecured guarantee (up to the full original loan amount, but never secured by your personal assets) and a conventional guarantee that may put your home directly on the line. What the plan controls is everything the score does not: the use of funds, the projections, the equity story, and the honest framing of the owner's financial position. Bridge Note, a Canadian business plan service that writes lender-ready plans for BDC, CSBFP, and big-bank loan applications, builds files with that division of labour in mind — the plan makes the strongest possible case on capacity, capital, and conditions, because a plan is required either way and character is the one C only you can supply. We never promise an approval; no plan writer can. We make sure the credit decision is made on a complete file.

Frequently asked questions

What personal credit score do I need for a business loan in Canada?

Plan around 650 as the practical working number. The Big Five banks typically want roughly 650–680 for small-business lending, and CSBFP lenders often prefer 650 or better even though the program publishes no minimum. BDC has no strict cutoff, but many approved borrowers sit in the mid-600s or higher, and a score below 600 significantly reduces the chances. Alternative and online lenders may go as low as roughly 550 at materially higher rates. Canadian scores from Equifax and TransUnion run on a 300–900 scale.

Will BDC lend to me if my bank already said no?

Sometimes — that is a large part of BDC's mandate — but a bank decline does not reset the credit assessment. BDC underwrites the same fundamentals: personal credit, cash flow, owner investment, and a credible plan. For businesses with 24 or more months of operating history, BDC can weigh demonstrated cash flow against a weaker score. But its own guidance is blunt that scores below 600 significantly reduce the odds, and its advisors describe good personal credit as the most critical requirement for loans under $350,000. BDC is a second reader of the same file, not a lender that ignores credit.

Can the lender take my house if my business loan goes bad?

It depends on the guarantee. On a CSBFP loan, the lender may take an unsecured personal guarantee up to the original amount of the loan disbursed, but that guarantee cannot be secured by your personal assets — your house is not pledged as collateral for it. On conventional loans, personal guarantees are often for the full amount and are sometimes secured; CFIB reports that more than half of recent borrowers signed a personal guarantee and one in four pledged their primary residence. Ask every lender, in writing, whether the guarantee is secured or unsecured.

Does my business credit score matter, or only my personal score?

For most small-business loans, personal credit does the heavy lifting — lenders reason that personal financial habits carry over into the business. A business credit file becomes more influential once the company has roughly 24 months of operating history, supplier trade lines, and its own borrowing record, at which point demonstrated business cash flow can offset a weaker personal score. For startups and loans under $350,000, expect the personal score to dominate.

My credit score is in the mid-500s. How do I improve my odds?

Work three levers at once. Repair the score where time allows: bring accounts current, reduce revolving balances well below limits, and correct errors on both Equifax and TransUnion files. Strengthen the rest of the file with a larger owner cash injection, collateral or a creditworthy co-signer, and documented explanations for past credit events. And match the lender to the file — alternative lenders approve scores near 550 at higher rates, which can bridge to a bank or BDC refinancing once the score and operating history improve. Disclose any CRA arrears proactively; undisclosed tax debt is a frequent automatic decline.
