What debt service coverage ratio do Canadian lenders want?

Ask what debt service coverage ratio Canadian lenders require and you'll find plenty of confident answers — most of them borrowed from U.S. SBA lending. Here is the honest Canadian picture: no Big Five bank publishes a numeric DSCR threshold, and BDC explicitly calls the benchmark "subjective," noting it "varies between lending institutions." What the market actually converges on is a 1.25× minimum as the widely cited commercial norm (Corporate Finance Institute), with BDC's own guidance treating around 2.0× as healthy and around 1.0× as unhealthy, and third-party characterizations putting BDC's practical floor near 1.2×. This guide covers the math underneath those numbers — how DSCR is calculated, how much leverage lenders accept, how amortization gets set by asset class — and what the repayment section of the plan has to show. (For building the projections that feed this math, see the companion guide on cash flow projections for a Canadian business loan; this article is the underwriting test those projections have to pass.)

What DSCR do Canadian lenders actually want to see?

Build the plan to clear 1.25× in the base case, with a target of 1.4× or better for cushion. That guidance is defensible; a single "required" number is not, and any article that gives you one without attribution is guessing.

What is actually on the record:

• BDC publishes the formula and qualitative benchmarks, not a threshold. Its guidance states a DSCR around 2.0 signals a healthy business and a ratio around 1.0 is unhealthy — every dollar of operating cash flow already committed to debt. Between those poles, BDC says the assessment is "subjective" and "varies between lending institutions."
• The 1.25× figure is a commercial-lending norm, not a Canadian rule. Corporate Finance Institute cites 1.25× as the general minimum commercial lenders look for, with roughly 2× preferred. It is a sound planning floor because so many credit teams use something near it — but no Canadian bank has committed to it publicly.
• The "1.2× BDC floor" is a third-party characterization. Advisory sources describe BDC's practical minimum as about 1.2×, with anything at or below 1.0× a disqualifier. BDC itself does not publish that number.
• None of RBC, TD, BMO, Scotiabank, or CIBC posts a DSCR threshold anywhere. Their commercial credit criteria are internal.

Why the honesty matters: an underwriter reading "the bank requires 1.25×" in a borrower's plan knows the borrower is reciting internet folklore. A plan that shows its coverage math and demonstrates headroom against the range of norms reads as written by someone who understands how the decision gets made — one of the three things every lender reads a plan for.

How is DSCR calculated — EBITDA or net income?

EBITDA divided by total debt service (principal plus interest). That is BDC's official formula, and it reflects how Canadian banks underwrite generally: on EBITDA, not net income. Net income already deducts interest and depreciation, so using it double-counts the cost of the very debt being tested; EBITDA isolates the operating cash flow available to service it.

Three adjustments determine whether your numerator survives contact with the underwriter:

1. Owner compensation. For an owner-operator, the owner-comp add-back applies — but only for work the owner will genuinely keep doing. If the departing seller of a business you're buying worked sixty-hour weeks and you plan to hire a manager, a fair-market replacement salary must be budgeted before coverage is calculated.
2. EBITDA, not SDE. Seller's discretionary earnings — which adds back the entire owner salary — is a valuation metric, not an underwriting metric. Lenders normalize back to EBITDA after fair-market compensation for whoever will run the company.
3. Add-backs need paper. Every normalization (one-time legal costs, personal vehicle, family on payroll) should be documented the way a skeptical reviewer would demand — because a skeptical reviewer will.

The denominator is the annual principal and interest on all debt — the proposed loan and every existing obligation the business will carry. A DSCR computed against the new loan alone, ignoring an existing equipment loan or shareholder loan with fixed repayment, is the single most common way plans overstate coverage.

A worked example: $300K EBITDA servicing an acquisition loan

Suppose you're buying an owner-operated distribution business with seller-stated EBITDA of $300,000. Senior acquisition debt commonly sizes around 3× EBITDA, so the bank term loan is $900,000 at 8% floating, amortized over 10 years.

Step 1 — normalize the earnings. The seller worked full-time; you will hire a general manager at $110,000. Adjusted EBITDA for coverage:

$300,000 − $110,000 = $190,000

Step 2 — compute the debt service. A $900,000 loan at 8% over 10 years costs about $10,920 per month, or roughly $131,000 per year in combined principal and interest.

Step 3 — the base-case DSCR.

$190,000 ÷ $131,000 = 1.45×

That clears the 1.25× commercial norm with the cushion lenders like to see.

Step 4 — the downside case. Stress it the way a credit file does:

• Revenue softens — EBITDA falls 15% to $161,500. DSCR: $161,500 ÷ $131,000 = 1.23×. Thin, but above the ~1.2× working floor.
• Add a rate rise. The loan is floating; at 10%, annual debt service climbs to roughly $142,700. DSCR: $161,500 ÷ $142,700 = 1.13×. Now the file is in territory most credit teams will not accept without restructuring.

This is exactly the arithmetic to show in the plan — base case with cushion, downside named honestly, and if the downside breaks coverage, the structural fix stated. The equity injection is not just a commitment signal; it is a DSCR lever.

How much leverage will Canadian lenders accept?

Keep debt-to-equity at or under 2:1. BDC's guidance describes a D/E ratio of roughly 2 to 2.5 as "good" and advises "not more than 2:1" for most businesses. For context, the average debt-to-equity across Canadian businesses runs around 1.5 (Statistics Canada financial statistics), so a plan levering past 2:1 is asking the lender to accept a balance sheet materially riskier than the national norm.

For acquisitions, the sizing rule shows up on the other axis: senior debt is commonly sized around 3× EBITDA. Purchase prices above that multiple get bridged with equity, vendor take-backs, and mezzanine — not more senior debt, because more senior debt breaks the coverage test. Leverage and coverage are the same constraint viewed from two directions.

What amortization will the lender give — and why does it change the DSCR?

Amortization is matched to asset life, and it is the quietest driver of the coverage calculation. A dollar borrowed over 25 years costs far less per year than the same dollar over 7 — so what the loan buys determines whether the cash flow can service it. The Canadian norms:

Lender	DSCR	Amortization	Leverage / rate
BDC	≥2 healthy; ~1.2 practical floor (third-party); below 1.0 disqualifier	Real estate 20–25 yr; equipment 5–12 yr (useful life)	D/E ≤2:1; BDC base + 2–6 pts
Chartered banks	1.25× minimum (commercial norm; not publicly posted)	Asset-matched	Prime + 1–3%
CSBFP	Lender's own test (viability-based)	Up to 15 yr most assets / 25 yr real property	Term loan cap prime+3%; LOC cap prime+5%

The asset-by-asset picture, per BDC's practice:

• Real estate: 20–25 years, with 25 typical and 20 for older or specialized property.
• Equipment: 5–12 years, tied to the useful life of the specific asset — a lender will not amortize a 6-year-life machine over 12 years.
• CSBFP loans: up to 15 years for most asset classes, up to 25 for real property.
• Goodwill and intangibles: shorter, cash-flow-based terms. There is no hard asset to resell, so the lender wants the exposure retired quickly — which is precisely why goodwill-heavy acquisitions strain DSCR and route toward vendor financing and mezzanine for the gap.

This makes the use-of-funds schedule and the repayment model one document in two views: each funded item implies an amortization, each amortization implies an annual payment, and the sum of those payments is the DSCR denominator. A model that amortizes everything over 15 years "because CSBFP allows it" will be repriced by the underwriter — and the coverage ratio moves when it is.

Is there a stress test on business loans in Canada?

No — and almost nobody writes this correctly. The interest-rate stress test Canadians know — qualifying at the higher of the contract rate plus 2% or the benchmark rate — comes from OSFI's Guideline B-20 and applies only to residential mortgages. There is no regulator-mandated buffer on business or commercial term loans. Articles claiming your business loan "must pass the stress test" are importing mortgage rules (or U.S. SBA practice) into a context where they don't apply.

What exists instead is discretionary and file-specific:

• Covenants — minimum DSCR or maximum leverage tests the borrower must maintain after funding, an early tripwire rather than an upfront buffer.
• Sensitivity analysis in the credit file — the borrower's projections get stressed before the file goes to credit. BDC expects best-case and worst-case sensitivity in loan files as standard practice.
• Pricing and structure — thinner coverage gets priced up, amortized shorter, or secured harder rather than declined by formula.

The takeaway: because no regulation imposes the stress test, the plan should impose it on itself. A repayment section that already shows coverage under a 15–20% EBITDA decline and a two-point rate rise has done the credit analyst's sensitivity work for them, in the borrower's own framing, with the mitigants attached.

What does the repayment section of the plan need to show?

Five things, in this order:

1. Monthly debt service against projected cash flow. The actual payment — at the rate, amortization, and term being requested, not placeholders — laid against the monthly cash-flow projection so coverage is visible month by month, not just annually.
2. The resulting DSCR, stated explicitly. Show the formula (EBITDA ÷ principal + interest), the normalization from reported earnings to lender-adjusted EBITDA, and the base-case ratio. Don't make the underwriter compute it.
3. Sensitivity scenarios. At minimum: a 15–20% EBITDA decline, and a rate rise if any of the debt floats. State the downside DSCR and what absorbs it.
4. Seasonality. An annual DSCR of 1.4× can hide three months of negative coverage in a seasonal business. The monthly view — plus the line of credit or cash reserve that bridges the trough — answers the question before it's asked.
5. Treatment of existing debt. Every current obligation, its payment, and whether it is retired, refinanced, or carried. Total debt service means total.

All of it should trace back to a linked three-statement financial model, so the cash flow that services the loan reconciles to the income statement and balance sheet rather than floating free of them.

And one structural rule: if the base-case DSCR is under roughly 1.2×, restructure rather than submit. More equity, longer amortization on assets that support it, a larger vendor take-back, or mezzanine for the goodwill gap — each shrinks the denominator. A declined file costs more than a delayed one. This is the discipline Bridge Note, a Canadian business plan service that writes lender-ready plans for BDC, CSBFP, and big-bank loan applications, applies before any plan leaves the shop: the repayment math gets built and stressed first, and if the structure can't clear coverage, the structure changes before the writing starts.

The bottom line

The most useful fact about Canadian DSCR requirements is that the published number you're looking for doesn't exist — BDC calls the benchmark subjective, and no chartered bank posts a threshold. Plan to the norms instead: EBITDA ÷ (principal + interest), a base case clearing 1.25× with cushion toward 1.4×, leverage at or under 2:1, amortization matched honestly to asset life, and a self-imposed stress test no regulator requires but every credit file effectively runs. No plan can promise an approval. It can make sure the math is never the reason for a decline.

Frequently asked questions

What DSCR do Canadian banks want to approve a business loan?

There is no published number. None of the Big Five banks posts a numeric DSCR threshold, and BDC describes the benchmark as subjective and varying between institutions. What the market converges on: a 1.25× minimum is the widely cited commercial norm (Corporate Finance Institute), BDC's guidance treats around 2.0 as healthy and around 1.0 as unhealthy, and third-party characterizations put BDC's practical floor near 1.2×. A plan built to clear 1.25× in the base case, with cushion toward 1.4×, is positioned for how Canadian lenders actually underwrite.

Is DSCR calculated on EBITDA or SDE for a business I'm buying?

Canadian lenders underwrite debt service on EBITDA, not net income and not SDE. SDE adds back the full owner's compensation and fits valuation conversations for owner-operated businesses; a lender's coverage test starts from EBITDA after a fair-market salary for whoever will actually run the business. If you will be the working owner-operator, the owner-comp add-back applies — but replacement labour must still be budgeted for any role the departing seller performed that you won't. A DSCR computed on unadjusted SDE overstates coverage and will be recalculated downward by the underwriter.

What amortization can I get on a goodwill-heavy acquisition loan?

Shorter than on hard assets. Amortization is matched to asset life: BDC finances real estate over 20–25 years and equipment over 5–12 years tied to useful life, and the CSBFP allows up to 15 years for most assets and 25 for real property. Goodwill and other intangibles have no resale value to amortize against, so lenders finance them on shorter, cash-flow-based terms — which raises annual debt service and makes the DSCR test harder to pass. That is why goodwill-heavy deals commonly add vendor take-backs or mezzanine to keep the senior debt serviceable.

Is there a stress test on business loans in Canada?

No — not a regulator-mandated one. The OSFI stress test (qualifying at the higher of the contract rate plus 2% or the benchmark rate) applies only to residential mortgages under Guideline B-20; there is no equivalent prescribed buffer for business or commercial term loans. Lenders build the buffer case by case — covenants, pricing, sensitivity analysis — and BDC expects best- and worst-case sensitivity in loan files. A plan should stress its own numbers even though no regulation requires it.

What should I do if my DSCR is below 1.2x?

Restructure the deal before you submit — don't hope the underwriter overlooks it. The levers: more equity to shrink the loan, longer amortization where the asset supports it, a larger vendor take-back so senior debt service falls, or mezzanine for part of the goodwill gap. Each reduces the principal-and-interest figure in the DSCR denominator. A file submitted below roughly 1.2× base-case coverage invites a decline that then sits on your record with that lender.
