Buyer and seller usually want opposite structures, for genuinely different reasons. Here is what each side is actually protecting, and where the trade-off can be split.
Key takeaways
STEP 01 OF 10
An individual who disposes of qualifying small business corporation shares can claim the lifetime capital gains exemption, currently stated in the Act as $625,000 of taxable capital gain — the taxable half of a $1,250,000 gain at the ½ inclusion rate — under ITA s.110.6. That figure indexes to the Consumer Price Index for taxation years beginning after 2025 under s.117.1(2)(c), so confirm the current indexed amount with an accountant rather than relying on the base statutory figure alone. An asset sale by the corporation does not give the individual shareholder access to this exemption in the same direct way — which is the single biggest reason a seller's advisors will push for a share structure.
STEP 02 OF 10
“Sellers often prefer a share sale for tax reasons, while buyers often prefer an asset sale because it lets them choose what they are taking on” — deavo's own summary at tax planning before you sell. In a share purchase, the buyer takes the target corporation “as a whole, including its history and any liabilities that were not specifically excluded in the purchase agreement” — undisclosed tax liabilities, pending litigation, environmental exposure and employment claims all travel with the shares unless expressly carved out and indemnified against. An asset purchase lets the buyer name, asset by asset and liability by liability, exactly what it is acquiring.
STEP 03 OF 10
This is the fact that most changes the negotiation in practice: the Canada Small Business Financing Program's own FAQ states plainly that a loan “cannot” finance “share purchases or assets that a holding company acquires.” Where a smaller deal was counting on CSBFP-guaranteed financing, a seller's insistence on a share structure removes that financing option entirely, forcing the buyer toward more expensive or harder-to-source conventional debt, more seller financing, or more buyer equity. See applying for CSBFP funding on a business purchase for the mechanics in full.
STEP 04 OF 10
Beyond eligibility, the security itself differs: on a share purchase, a lender typically takes “a pledge of the target's shares, plus a guarantee and security from the target company itself,” with broader diligence into the target's own corporate history; on an asset purchase, a lender typically registers “PPSA registration directly against the purchased assets — equipment, inventory, receivables — as identifiable collateral,” with narrower diligence focused on the specific assets. See how lenders finance share vs asset purchases.
STEP 05 OF 10
On a going-concern business sale, the joint election under ETA s.167 lets an asset sale proceed with no GST/HST payable on most of the transferred property, provided the buyer is a registrant. Goodwill is separately excluded from GST/HST altogether under s.167.1, regardless of the election. A share sale, by contrast, is not a taxable supply at all under the Excise Tax Act — shares are financial instruments, outside the GST/HST system entirely. Both structures can reach a low- or no-GST/HST outcome; they just get there through different provisions, and the asset route depends on filing the election correctly and on time.
STEP 06 OF 10
This is a genuinely under-considered layer. In Saskatchewan, a share purchase is explicitly not subject to PST, while an asset sale can trigger a bulk-sale clearance certificate requirement and buyer self-assessment within 30 days. In British Columbia, the opposite collection rule applies on an asset sale — the seller, if a PST collector, remits — and shares of a business are separately listed as not taxable. In Manitoba, an asset-based “sale in bulk” shifts the reporting obligation to the buyer, with the seller obliged to obtain a clearance certificate first. None of these are federal rules, and none of them track each other — check the specific province a target operates in before assuming the tax treatment carries across provincial lines.
STEP 07 OF 10
Employment continuity rules generally apply regardless of whether a business changes hands by share sale or asset sale — what changes is less the employment law answer and more the practical mechanics of who the employer becomes. Ontario's non-compete carve-out for a departing seller, for instance, is written around “a sole proprietorship or a partnership,” which on its face does not clearly extend to the far more common Ontario deal shape of a corporate share sale where the seller stays on — a real gap worth raising with counsel rather than assuming either structure resolves it cleanly.
STEP 08 OF 10
A hybrid deal — carving specific assets into an asset-purchase sleeve while the remainder of the business transacts as a share sale, or the reverse — is a genuine, workable middle ground where a seller's LCGE position and a buyer's financing or liability concerns cannot both be fully satisfied by a single pure structure. It adds documentation complexity, but it is a real option worth raising early in the negotiation rather than treating the choice as strictly binary.
STEP 09 OF 10
Because each structure shifts real economic value — tax exposure, financing cost, assumed risk — between buyer and seller, the structure decision and the price negotiation are not actually separable. A seller demanding a share sale is, in effect, asking the buyer to absorb a financing and liability cost the buyer would not otherwise carry; that cost belongs in the price conversation, explicitly, rather than being treated as a free-standing structural preference with no bearing on value.
STEP 10 OF 10
The structure choice touches the closing checklist, the lender package, the tax elections and the security a lender will take — see working through the closing checklist and preparing a lender package a bank will approve. Settle this question as early in the deal as possible — ideally before the letter of intent — because unwinding an assumed structure late in the process costs both sides real time and legal fees.
Treating the structure decision as a legal technicality rather than a value question. Each structure shifts real economic cost between buyer and seller — tax exposure, financing access, assumed liability. It belongs in the price negotiation, not a side conversation handled by lawyers alone.
Assuming CSBFP financing is available without confirming the structure first. The programme refuses share purchases outright. A financing plan built before the structure is settled can collapse the moment a seller insists on shares.
Assuming GST/HST and provincial sales tax follow the same logic. They do not. A structure that is efficient federally under the ETA s.167 election can still trigger a real provincial sales tax obligation, and the specific province's rule has to be checked on its own.
Leaving the structure question unresolved until diligence is well underway. Nearly every downstream item — the lender package, the closing checklist, the tax elections — depends on the structure. Decide it as early as the deal allows.
To illustrate the mechanics only — the figures are a drafting choice for this example, not a benchmark, and the rate used below is stated only to show the arithmetic.
Scenario A. As an asset purchase: the buyer finances $900,000 through a CSBFP-guaranteed term loan against eligible equipment and leaseholds, $300,000 through buyer equity, and $300,000 through a five-year vendor take-back. The seller pays corporate-level tax on the asset sale gain before any distribution to shareholders, with no access to the lifetime capital gains exemption on this structure.
Scenario B. As a share purchase at the same $1,500,000 price: the seller, an individual holding qualifying small business corporation shares, claims the lifetime capital gains exemption against $625,000 of the taxable gain — a meaningful after-tax benefit to the seller. The CSBFP-guaranteed layer from Scenario A is no longer available at all, so the buyer must replace that $900,000 with a larger vendor take-back, more equity, or a conventional bank facility carrying its own, likely higher, coverage requirements.
The seller's after-tax outcome improves materially under the share structure; the buyer's financing gets meaningfully harder. Neither side is wrong to want its preferred structure — the negotiation is about which side absorbs, or shares, that trade-off in the price.
Three provinces, three different collection rules on the identical transaction.
These are provincial rules layered on top of, not instead of, the federal GST/HST treatment — check both.
No — the exemption belongs to the individual selling shares, not to the corporation selling assets. An asset sale simply does not engage the exemption on the buyer's side of the transaction at all.
Not necessarily more expensive, but it is structurally different — it cannot use CSBFP financing at all, and a lender typically requires a share pledge and a guarantee from the target rather than asset-specific PPSA registration, which usually means broader diligence.
A single deal split into an asset-purchase sleeve and a share-purchase sleeve, used where a seller's tax position and a buyer's financing or liability concerns cannot both be satisfied by one pure structure. It adds complexity but is a genuine, workable option.
A short call can map the tax, financing and liability trade-offs against your numbers.
