How Business Credit and Personal Credit Scores Differ in Canada

Business credit is a separate file from your personal credit score and works differently. A registered business name, trade accounts and time help build it.

What business credit means in Canada

Business credit is the record of how a business borrows and repays money in its own name. It is not a single number. Canada has no universal commercial score that every lender checks the way a consumer score is pulled from a bureau. A business credit profile is assembled from several sources: commercial reporting files, trade references from suppliers, banking history, public records such as registered liens, and the lender's own records.

That fragmentation is the biggest practical difference from personal credit. Most adults with a Canadian credit history have two consumer files that broadly agree with one another. A company can have a thin or non-existent commercial file and still be financeable, which is why lenders lean so heavily on the owner's personal credit when the business is small.

Who can hold a business credit file

Corporations, partnerships and sole proprietors can all build a commercial profile, but the quality of that profile depends on structure. An incorporated company has a registration number, a separate legal identity, and the ability to hold accounts, sign leases and borrow in its own name. A sole proprietor is the business for legal purposes, so commercial and personal borrowing are effectively the same activity.

Why the owner's personal file still matters

For most small and mid-sized Canadian businesses, the lender reviews the owner's personal credit alongside the company's. A personal credit score is a numeric assessment built from an individual's repayment history, and lenders treat it as a signal of how the principals behave with debt. Many commercial facilities also require a personal guarantee, meaning the owner agrees to answer for the debt if the business does not.

How business credit differs from a personal credit score

How a business credit profile gets built

Building a commercial file is deliberate rather than automatic. A company that pays every supplier by credit card and never asks for terms may have almost nothing on file.

1. Separate the money. Open a business bank account and route every business transaction through it. Commingling personal and business spending blurs the record a lender is trying to read.
2. Register the name and get a business number. A registered legal name and a business number give the entity an identity that suppliers and lenders can search and report against.
3. Open trade accounts. Ask suppliers, wholesalers or service providers who extend net terms to invoice the business. Those accounts become trade references.
4. Take a modest amount of commercial credit and repay it as agreed. A business card, a small equipment loan or a lease each create repayment history.
5. File and pay on time. Payroll remittances, sales tax and corporate income tax obligations form part of the record a lender may consider. If personal instalments apply to you, CRA individual tax instalments are due 15 March, 15 June, 15 September and 15 December, and they may be required where net tax owing exceeds $3,000 for the current year and either of the two prior years — $1,800 in Quebec — while farmers and fishers have a single due date of 31 December.
6. Ask whether your supplier reports. Not every trade account feeds a commercial file, so prioritise the ones that do.

What lenders actually weigh

• Length and depth of the commercial file, or the absence of one.
• Trade payment behaviour — whether invoices are paid on terms or consistently late.
• Financial statements, revenue trend and debt-service capacity.
• Owner personal credit and net worth, especially for smaller facilities.
• Collateral, security registration and any guarantees offered.
• Industry and concentration risk, such as how much revenue depends on one customer.

Where the legal rules diverge

Consumer lending in Canada carries protections that commercial lending largely does not. The criminal rate of interest is 35% APR, reduced from 48% under Criminal Code s.347. That ceiling applies to credit generally, but the consumer-specific overlay — mandatory cost-of-borrowing disclosure, cooling-off rights and complaint handling — is built around personal borrowing.

Payday lending sits outside business credit

Payday loans are a consumer product, not a commercial one. Where a province has a payday lending regime, the cost is capped at $14 per $100 borrowed, the dishonoured-payment fee is capped at $20, and the maximum payday loan is $1,500. Quebec does not permit payday lending at all, and the maximum rate of credit there is 35% per year. The FCAC illustration of a 14-day $500 payday loan at $14 per $100 costs $70, which works out to roughly 365% APR. Nothing comparable exists in commercial trade credit, which is why payday-style borrowing should never be treated as working capital for a business.

Mortgage-style rules and the Interest Act

Borrowing against real property to fund a business usually pulls in underwriting rules built for residential mortgages. Federally regulated lenders qualify borrowers under OSFI Guideline B-20 at the greater of the contract rate plus two percentage points or 5.25%. Minimum down payment is 5% on the portion up to $500,000, 10% on the portion from $500,000 to $1,500,000, and 20% above $1,500,000; a down payment under 20% requires mortgage default insurance, and the maximum amortization for an insured mortgage is 25 years. Separately, Interest Act s.4 provides that where a mortgage or agreement for sale provides for interest but does not state an annual rate, interest is not chargeable above 5% per annum — a reminder to check how a rate is expressed, not just its size.

Promissory notes and personal guarantees

Much business lending is documented with a promissory note: a written, signed, unconditional promise to pay a sum certain in money under Part IV of the Bills of Exchange Act. Signing one as an individual, or signing a guarantee, is the point where business credit turns personal again. Because a guarantee is a separate personal obligation, it is not automatically extinguished if the corporation runs into difficulty, and insolvency proceedings overseen by the Office of the Superintendent of Bankruptcy do not simply erase it. Anyone facing that situation should speak with a licensed insolvency trustee or a lawyer.

What this means in practice

Business credit and personal credit are related but not interchangeable, and strength in one does not repair weakness in the other.

• A corporation's file does not replace the owner's score for smaller-ticket lending.
• A clean personal score does not create a commercial track record where none exists.
• Trade references are worth asking for explicitly, because unreported good behaviour does nothing for you.
• Guarantees convert business risk into personal risk, so the personal balance sheet stays relevant after incorporation.
• Whenever a lender pulls your personal file, that is a personal credit event, and a hard inquiry may affect your score.

Getting started without overcommitting

A sensible sequence is to separate the banking, ask two or three suppliers for net terms, and take a modest commercial facility you can repay comfortably, then let that history accumulate before applying for something larger. Check your personal files with the two national bureaus first, since a lender will look at them, and compare product shapes carefully — a business line of credit and a term loan behave very differently over time.
