Every acquisition is financed from the same three sources in different proportions. Here is how to size each layer, in order, and where the tax rules quietly cap one of them.
Key takeaways
STEP 01 OF 10
Capital-stack proportions shift meaningfully with deal size, so size the deal before you size the financing. Deavo's financing tool, built on Statistics Canada and ISED small-business data, splits Canadian acquisitions into three bands: micro/main-street ($200,000–$1,000,000), small ($1,000,000–$5,000,000) and mid-market ($5,000,000–$30,000,000) — see the bands at deavo's financing overview. Each band carries a different typical equity share, a different senior-debt source, and a different underwriting basis, which is why the rest of this guide is organized by layer, not by a single universal ratio.
STEP 02 OF 10
Equity is “first money in, last money out,” and lenders read the size of it as a signal of commitment before they read anything else in the file. On the smallest deals, buyer equity is commonly personal savings, often with a family member or partner; on mid-market deals with a sponsor or search-fund buyer, equity commonly runs 35–45% of the price. These are deavo's own illustrative figures, not a rule, and every lender sets its own minimum — treat the band as a starting assumption to test against your specific lender's appetite, not a target to hit exactly.
STEP 03 OF 10
A vendor take-back exists because third-party lenders “often limit how much of a purchase price they will finance, particularly when a meaningful share of the value sits in goodwill rather than hard assets that can be pledged as collateral” — deavo's own framing at vendor take-backs, explained. It also signals confidence: a seller willing to carry paper on their own sale is vouching for the business in a way a bank appraisal cannot. Whatever share you agree, expect the seller's lawyer to insist on standstill or subordination terms ranking the take-back behind any senior lender, and on registering security under the applicable province's personal property security legislation.
STEP 04 OF 10
A seller accepting deferred payments is not simply choosing a payment schedule — they are relying on the Income Tax Act's reserve provision to defer the related tax. Under s.40(1)(a)(iii), the reserve is capped at roughly one-fifth of the gain per year, over a maximum of five taxation years, for an ordinary arm's-length sale — read the mechanics at ITA s.40. A ten-year reserve only exists on three specific routes: a sale to the seller's child under s.40(1.1), an intergenerational transfer meeting the conditions in ITA s.84.1(2.31) or (2.32) under s.40(1.2), or a disposition to an employee ownership trust under s.40(1.3). An ordinary third-party VTB — the kind this guide is about — is on the five-year clock, even where deavo describes typical VTB terms running “10–20% over 3–5 years,” which sits comfortably inside it.
STEP 05 OF 10
On a smaller deal, senior debt is commonly a bank term loan with a Canada Small Business Financing Program guarantee behind it; on a mid-market deal it is more often a commercial bank or BDC facility underwritten on EBITDA. Whichever source, the lender is financing specific eligible assets or cash-flow capacity — not simply matching whatever price the buyer and seller agreed. See applying for CSBFP funding on a business purchase for exactly which assets qualify and where the real ceiling sits inside the programme's headline figure.
STEP 06 OF 10
Below that scale, most Canadian small-business deals do not carry a mezzanine layer at all — the stack is simply equity, seller paper and senior debt. Above it, a subordinated layer commonly appears between the senior lender and the sponsor's equity, priced higher to compensate for its junior position. Do not price mezzanine into a sub-$5 million deal model; it distorts the return math on a deal that will not carry that layer in practice.
STEP 07 OF 10
A lender's appetite is not just about the dollar amount — it is about whether the business's own cash flow will service the debt on top of everything else the buyer is layering in. Underwriting basis and the target coverage ratio both shift with deal size and the earnings measure the lender uses (seller's discretionary earnings on the smallest deals, EBITDA above roughly $1 million) — build your own model against the ratio your specific lender quotes rather than assuming one figure carries across every deal.
STEP 08 OF 10
A bank loan runs on the lender's own underwriting timeline — “a review of the buyer's personal financial position, the target business's financial statements, and often a business valuation or appraisal the lender commissions independently.” A vendor take-back is negotiated directly between buyer and seller and does not sit behind a separate underwriting process — in principle faster, though it still needs proper documentation, security registration and subordination terms once a bank is also in the deal. Deavo's own advice is to run both tracks “in parallel, not sequentially” — see bank loan vs vendor financing. Sequencing them adds weeks to a closing timeline for no offsetting benefit.
STEP 09 OF 10
A seller who wants a share sale for the lifetime capital gains exemption is, at the same moment, closing off CSBFP financing for the buyer — the programme's own rules refuse to finance a share purchase outright. See choosing between a share deal and an asset deal for how that trade-off is usually resolved, and price the consequence into whichever side of the capital stack absorbs it — typically a larger equity or vendor-take-back component standing in for the CSBFP dollars a share deal cannot access.
STEP 10 OF 10
A capital stack that clears the lender's minimum coverage ratio at the base case can still fail if revenue softens in year one — and a first-year miss after closing is common enough to plan for; see turning around an underperforming acquisition. Run the same coverage math at a meaningfully lower earnings figure before you finalize the stack, not after the first quarter's numbers come in short.
Assuming one universal debt-to-equity ratio applies at every deal size. The typical mix shifts materially between a $300,000 main-street purchase and a $10 million sponsor-backed deal. Size the stack against your own band, not a rule of thumb from a different one.
Reporting a vendor take-back's gain over ten years by default. The ordinary reserve under ITA s.40 caps deferral at five years. Ten years is available only on an intergenerational transfer or an employee-ownership-trust sale meeting specific statutory conditions — not on an ordinary arm's-length VTB.
Negotiating the bank loan first, then bringing the vendor take-back to the table. Running the two tracks sequentially adds weeks to closing for no benefit; a subordination clause can be drafted once both terms are known, not before.
Sizing mezzanine debt into a deal too small to carry it. Below roughly $5 million, most Canadian small-business acquisitions do not have a mezzanine layer at all — modelling one distorts the return math.
To illustrate the mechanics only — the proportions are a drafting choice for this example, not a published benchmark — here is one way a small-deal stack might be built.
Scenario A. A buyer is acquiring a business for $2,000,000. Buyer equity of 25% ($500,000) is committed first. A vendor take-back of 15% ($300,000) is negotiated at a 5-year term, inside the ordinary reserve's five-year ceiling, subordinated behind the senior lender. The remaining $1,200,000 is financed as senior debt: because the eligible-asset test caps CSBFP term-loan dollars at $1,000,000, the buyer places $1,000,000 through a CSBFP-guaranteed bank loan against eligible equipment, leaseholds and real property, and the balance of $200,000 through a separate conventional facility the bank underwrites outside the programme, secured against the same collateral pool.
Scenario B. The same buyer instead structures the deal as a share purchase because the seller wants the lifetime capital gains exemption. The $1,000,000 CSBFP layer from Scenario A is no longer available at all — the programme will not finance shares — so that gap has to be closed with a larger vendor take-back, more buyer equity, or a conventional bank facility underwritten without any government guarantee behind it, typically at a higher required coverage ratio.
Neither scenario is a claim about what a specific lender will approve. The point is structural: the same $2,000,000 price can require a materially different stack depending on one decision made earlier in the deal.
Deavo's financing tool sets out the shift by band — read the figures as illustrative, not as a lender's commitment.
Treat these as a starting model to test against your own lender and deal, not as fixed targets.
The opposite, generally — deavo frames a VTB as the seller signalling confidence in the business by staying financially exposed to its performance after closing. Lenders often read it the same way.
No. The ordinary capital gains reserve under ITA s.40 caps an arm's-length sale at five years. Ten years is available only on a sale to the seller's child, a qualifying intergenerational transfer, or a disposition to an employee ownership trust — each with its own statutory conditions.
Neither — run both in parallel. Sequencing them adds time to closing without improving either negotiation, and a subordination clause can be finalized once both sets of terms exist.
A short call is enough to test your deal against the right band.
