A business line of credit interest rate in Canada typically ranges from 5% to 14% for traditional lenders, though rates can vary significantly based on your business profile and the type of lender. Understanding these rates and what influences them helps you secure the most cost-effective financing for your business.

Current Business Line Rates
Business line of credit interest rates in Canada are structured as a variable rate tied to the lender’s prime rate, plus a margin that reflects your business risk profile. As of March 2026, major Canadian banks have prime rates ranging from approximately 4.45% to 5.45%.
The total rate you pay combines this prime rate with an additional spread. For example, BMO’s Credit Line for Business offers rates from prime plus 2% to prime plus 11%, meaning qualified borrowers could access rates as low as 6.45%, while higher-risk profiles might see rates around 16.45%.
| Lender Type | Typical Rate Range | Best For |
|---|---|---|
| Big Banks (CSBFP) | Prime + 3% (~7.5% to 8.5%) | Established businesses with strong credit |
| Big Banks (Standard) | Prime + 2% to 5% (~6.5% to 10.5%) | Businesses with good credit history |
| Credit Unions | 11.95% to 13.95% | Self-employed, local businesses |
| B Lenders | A rate + 1.25% to 2% | Bruised credit, exceptions needed |
| Alternative Lenders | 15% to 30%+ | Fast approval, flexible criteria |
Rates and terms may vary by financial institution. These ranges reflect market averages as of March 2026 and are subject to change based on Bank of Canada policy decisions and individual lender criteria.
How Rates Are Determined
Lenders evaluate multiple factors when setting your business line of credit interest rate. Unlike consumer lending, business rates reflect both personal and business financial health, making the assessment more comprehensive.
- Credit Score: Personal credit scores of 680 or higher typically qualify for the best rates at traditional banks, while alternative lenders may work with scores as low as 550 to 600.
- Business Revenue: Most traditional lenders require minimum annual revenue of $100,000 to $250,000, with higher revenue often unlocking lower rates and larger credit limits.
- Time in Business: Established businesses with two or more years of operating history generally receive more favourable terms than startups or newer ventures.
- Debt Service Coverage Ratio: Lenders calculate your ability to service debt by comparing operating income to debt payments, typically looking for a ratio above 1.25.
- Industry Risk: Certain sectors such as construction or hospitality may face higher rates due to perceived volatility, while professional services often qualify for lower rates.
- Collateral Type: Secured lines backed by real estate, equipment, or accounts receivable typically offer rates 2% to 5% lower than unsecured options.
The Canada Small Business Financing Program (CSBFP) offers government-backed lines of credit up to $150,000 at a standardized rate of prime plus 3%. This programme is available through most major banks and many credit unions for businesses with annual gross revenues under $10 million.
Prime Rate Impact
The prime rate serves as the foundation for most business line of credit pricing in Canada. When the Bank of Canada adjusts its overnight rate, financial institutions typically adjust their prime rates within days, which directly affects your borrowing cost if you hold a variable-rate line.
As of March 2026, the Bank of Canada’s benchmark rate influences prime rates at major institutions, which range from approximately 4.45% at some credit unions to 5.45% at larger banks. Your total rate equals this prime rate plus your approved margin.
Secured vs Unsecured Lines
The choice between secured and unsecured business lines of credit significantly impacts both your interest rate and available credit limit. Each option serves different business situations and risk profiles.
Secured Business Lines
Secured lines require collateral such as real estate, equipment, inventory, or accounts receivable. This collateral reduces lender risk, which translates to lower interest rates and higher credit limits for your business.
- Lower Rates: Secured lines typically offer rates 2% to 5% below unsecured options, potentially saving thousands in annual interest costs.
- Higher Limits: Credit limits can extend to $500,000 or more, depending on collateral value and business financials.
- Longer Terms: Many secured lines offer more flexible repayment periods and draw periods compared to unsecured alternatives.
- Asset Risk: Your collateral is at risk if you cannot meet repayment obligations, potentially affecting business operations.
- Longer Approval: Secured lines require appraisals and legal documentation, extending approval timelines to two to six weeks.
- Additional Costs: Expect appraisal fees, legal fees, and registration costs that can total $1,000 to $3,000 or more.
Unsecured Business Lines
Unsecured lines require no collateral and are approved based solely on creditworthiness, revenue, and business financials. This makes them faster to obtain but more expensive in terms of interest rates.
- No Collateral Required: Your business assets remain unencumbered, preserving flexibility for future financing needs.
- Faster Approval: Many unsecured lines can be approved within 24 to 72 hours, with some same-day decisions available.
- Lower Upfront Costs: No appraisal or legal fees means lower initial expenses to establish the credit facility.
- Higher Rates: Unsecured lines typically carry rates 2% to 10% above secured alternatives, increasing your cost of borrowing.
- Lower Limits: Credit limits generally range from $10,000 to $250,000, which may not meet larger capital needs.
- Stricter Qualifications: Lenders compensate for higher risk with more rigorous credit score and revenue requirements.
Ways to Secure Lower Rates
Several strategies can help you qualify for the most competitive business line of credit rates. Taking action in these areas before applying strengthens your position with lenders and can save thousands in interest over the life of your credit facility.
- Build Business Credit: Establish trade credit with suppliers, maintain a business credit card with on-time payments, and register with Dun & Bradstreet to create a verifiable business credit history separate from your personal profile.
- Improve Personal Credit: Since most lenders consider personal credit scores for business lines, focus on paying down existing debt, correcting any errors on your credit report, and maintaining credit utilization below 30%.
- Increase Revenue Documentation: Prepare clean financial statements showing consistent or growing revenue over multiple years, as this demonstrates stability and repayment capacity to lenders.
- Offer Collateral: If you have real estate, equipment, or other valuable assets, securing your line of credit can reduce your rate by 2% to 5% compared to unsecured options.
- Compare Multiple Lenders: Rate differences between institutions can be substantial; exploring options across big banks, credit unions, and alternative lenders helps identify the best terms for your specific situation.
- Reduce Debt Service Ratio: Paying down existing business debt before applying improves your debt service coverage ratio, demonstrating stronger repayment capacity to potential lenders.
For businesses exploring multiple financing options, reviewing business credit cards alongside lines of credit can reveal which tool best matches your specific cash flow patterns and spending needs.
Bottom Line
Business line of credit interest rates in Canada range from approximately 6% for well-qualified borrowers at traditional banks to 30% or higher from alternative lenders. Your final rate depends on credit profile, collateral, revenue, and the type of lender you choose.
Traditional banks and the Canada Small Business Financing Program offer the lowest rates but require stronger credit and longer approval times. Alternative lenders provide faster access with more flexible qualification criteria, though at higher cost. Secured lines consistently deliver rates 2% to 5% below unsecured options.
Before applying, compare multiple lender types to identify the best balance of rate, limit, and approval speed for your situation. Building business credit, improving personal credit scores, and preparing clean financial documentation strengthens your position and helps secure more favourable terms.
