Business Line of Credit in Canada: How It Works & How to Qualify

What a business line of credit is

A business line of credit is revolving credit: a lender approves a limit, you draw against it whenever you need cash, you pay interest only on the outstanding balance, and every repayment restores your available room. Draw $20,000 of a $50,000 line, repay $5,000, and you owe interest on $15,000 while $35,000 sits ready for the next need. Unlike a term loan, there's no fixed amortization clock ticking on money you haven't used.

That flexibility is why a line is many Canadian businesses' first-choice safety net: it costs little or nothing to hold when undrawn (some lines carry small annual or standby fees) and it's there the day a truck breaks down or a big invoice pays late. Our business lines of credit hub covers the product in depth; this article focuses on how it works in Canada specifically.

How Canadian lines are priced: the prime-rate link

Almost every Canadian business line floats. Pricing is quoted as prime + a margin — prime plus 1%, prime plus 3%, and so on, with the margin reflecting your risk profile and whether the line is secured. "Prime" here is the prime rate posted by Canadian banks, which moves in step with the Bank of Canada's overnight policy rate. Major-bank prime rates have generally sat a couple of percentage points above the Bank of Canada's policy rate in recent years {{VERIFY: current Canadian bank prime rate and its spread over the BoC overnight rate — Bank of Canada and major bank posted rates}}.

The practical consequence: when the Bank of Canada hikes, your carrying cost on a drawn balance rises within days — and when it cuts, your cost falls. Budget for rate movement in both directions. If you carry a large balance for a long stretch, a floating line is effectively a bet on rates, which is one argument for converting persistent balances into fixed-rate term debt.

Banks vs online providers

Canadian banks and credit unions offer the cheapest lines — typically the lowest margins over prime — but the door is narrower. Expect requests for financial statements, possibly two or more years of operating history, strong owner credit, and sometimes collateral or a general security agreement. Approval can take weeks.

Online and alternative providers approve faster, often within days, using bank-statement data instead of full financials. They'll consider younger businesses and lower credit scores, but the trade-offs are real: higher effective costs, smaller limits, shorter draw terms, and repayment structures that can look more like short amortizing loans than true revolving credit. Read the mechanics carefully — some products marketed as "lines" require each draw to be repaid on a fixed weekly schedule.

If a line turns out to be the wrong fit, the broader menu of business loans — and our guide to small business loans in Canada — cover the alternatives.

What lenders look at

Every provider weighs these differently, and none of this is a promise of approval — each lender makes its own decision.

Secured vs unsecured

A secured line is backed by collateral — receivables, inventory, equipment, investments, or real property — usually documented through a general security agreement registered under provincial PPSA rules. Security buys you a lower margin over prime and a higher limit. An unsecured line skips specific collateral but almost always still requires a personal guarantee, and it costs more and caps lower. If you have clean collateral and want the cheapest possible standby credit, secured is usually worth the paperwork.

When a line beats a term loan

Reach for a line when the need is recurring, variable, or uncertain: smoothing seasonal cash flow, bridging slow-paying customers, covering payroll in a soft month, or simply holding dry powder for emergencies. You pay only for what you draw, when you draw it.

Reach for a term loan when the need is single, large, and defined: equipment, a build-out, an acquisition. Fixed payments on a known amount are easier to plan around, and term rates on secured purchases often beat line rates. And if your need might fit a government-supported program — the Canada Small Business Financing Program, for instance — see our guide to government business loans in Canada before defaulting to private options.

A useful rule of thumb: if you'd draw the full amount on day one and repay it over years, you wanted a term loan. If the balance would rise and fall with your business, you wanted a line. Model both against your cash flow with the line of credit calculator.

The honest downsides

Lines get cut. Lenders can reduce or freeze a limit when your financials weaken or the economy turns — often exactly when you need it most, which is why the time to open a line is when business is good. Floating rates rise without warning. Easy access tempts businesses into treating the line as permanent capital, paying prime-plus forever on a balance that never goes down. And personal guarantees mean the debt can follow you if the business fails.

BluLoans is an education and comparison platform, not a lender. Businesses with steady monthly deposits can compare options through our funding partner, which serves all Canadian provinces — but the qualification decision always belongs to the provider, and the best preparation is the same everywhere: clean bank statements, a clear use case, and the discipline to keep the line revolving instead of stuck at its limit.
