A full audit-grade quality of earnings review is not always the right tool for a lower-middle-market deal. Here is how to scope a credible one without the Big Four price tag.
Key takeaways
STEP 01 OF 10
CBV Institute’s practice standards, in force for engagements beginning on or after 1 January 2026, are organized into families by depth: full Valuation Conclusions and Reports (Standards 100/110/120/130), Advisory Reports (210/220/230), Expert Reports (310/320/330), Limited Critique Reports (410/420/430), and Fairness Opinions (510/520/530). A Limited Critique engagement is the scoped, lighter-touch tier — commissioning one from a CBV, rather than a full audit-grade engagement from a large firm, gets a lower-middle-market deal a professional, standards-based opinion sized to what the deal can actually support.
What this sheet cannot tell you is exactly what a Limited Critique tier is required to cover, since the individual standards are published as PDFs and the specific scope requirements were not read for this guide — ask the CBV directly what their engagement letter covers under Standard 410 before assuming it matches what a full quality-of-earnings review would deliver.
STEP 02 OF 10
ITA s. 230(4)(b) requires records and books of account, “together with every account and voucher necessary to verify the information contained therein,” to be retained “until the expiration of six years from the end of the last taxation year to which the records and books of account relate.” Electronic records must be kept “in an electronically readable format” for the same period under s. 230(4.1).
That gives a buyer a genuine floor to request against, not a courtesy: the target is legally required to have six years of records on hand (or, where a return was not filed for some period, six years from the day it was filed, per s. 230(5)). A seller who cannot produce that set is either disorganized or hiding something — either way, it changes how much reliance the rest of this diligence can place on what is produced.
STEP 03 OF 10
ITA s. 20(1)(p) allows a deduction for “all debts owing to the taxpayer that are established by the taxpayer to have become bad debts in the year and that have been included in computing the taxpayer’s income for the year or a preceding year.” The second half of that test is the useful diligence tool: a receivable that was never included in income in the first place — because it represents, say, an inflated intercompany balance or a shareholder loan dressed up as trade AR — cannot be written off as a bad debt at all, which is itself a signal worth chasing.
Cross-reference the aging schedule against what was actually reported as revenue in the corresponding tax year. A gap between the two is either a timing difference worth understanding or evidence the receivables balance does not mean what it appears to mean.
STEP 04 OF 10
ITA s. 125 caps a CCPC’s small business deduction at a $500,000 business limit, taxed at a 19% SBD rate for days after 2018 — but that limit is shared across every CCPC the target is associated with after closing. If the buyer already owns other CCPCs, acquiring the target can immediately shrink the effective business limit available to the group, with no change to the target’s own operations.
Two further grinds sit in the same section: a taxable-capital grind reducing the business limit on a straight-line basis between $10 million and $50 million of taxable capital, and a passive-income grind that reduces the limit against adjusted aggregate investment income, fully eliminated at $150,000 of AAII. A target sitting on redundant investment assets — a large cash balance parked in marketable securities, for instance — carries this grind with it into the buyer’s group. Worked example: if the target alone has $80,000 of AAII, the grind formula reduces the $500,000 limit by 5 × ($80,000 − $50,000) = $150,000, down to $350,000 available — before even accounting for any other CCPC the buyer already owns.
STEP 05 OF 10
ETA s. 167(1)(b) makes the joint election unavailable “where the supplier is a registrant and the recipient is not a registrant.” If the deal is structured as an asset purchase and the target is GST/HST-registered, the buyer’s own registration status is not a formality — it is a precondition to avoiding tax on the transaction. Confirm the acquiring entity is registered, or will be by closing, before the purchase agreement assumes the election is available.
Also confirm goodwill is being treated correctly: under s. 167.1, consideration reasonably attributed to goodwill is excluded from GST/HST entirely, separate from and in addition to the s. 167 election.
STEP 06 OF 10
On an asset purchase, request a clearance certificate as a diligence item, not an afterthought. In Saskatchewan, PST Bulletin PST-77 warns that “failure to obtain a copy of this certificate could result in the purchaser or seller being held liable for any outstanding taxes unpaid by the seller,” enforceable against the buyer under s. 51 of the Revenue and Financial Services Act. In British Columbia, a purchaser without a clearance certificate “is liable for an amount equal to any outstanding amount owed by the collector.” Manitoba’s Tax Administration and Miscellaneous Taxes Act makes the buyer liable on assessment for the seller’s tax debt unless the buyer obtains the seller’s duplicate clearance certificate.
The three provinces even disagree on who normally remits the tax in the first place — Saskatchewan and Manitoba put the burden on the buyer to self-assess and remit, British Columbia puts it on the seller if the seller is a collector. Confirm which regime applies to the province the assets sit in before assuming the standard practice from your last deal carries over unchanged.
STEP 07 OF 10
In Ontario, an employee qualifies for statutory severance pay on top of notice if they have five or more years of service and the employer either has a global payroll of at least $2.5 million or severed 50 or more employees in a six-month period due to a permanent closure. “Global payroll” means the employer’s payroll everywhere, not just at the target — a target that looks too small on its own to trigger this test can trigger it immediately once it becomes part of the buyer’s larger group.
Notice entitlement runs from one week for under a year of service up to a statutory maximum of eight weeks at eight years or more; severance, where it applies, is capped at 26 weeks. Model both against the target’s actual tenure roster before closing, not against an assumption carried over from a different deal.
STEP 08 OF 10
Competition Act s. 109(1) exempts a transaction from the notification regime unless the parties, together with their affiliates, have assets in Canada or gross revenues from sales in, from or into Canada exceeding $400,000,000 in aggregate — a threshold most lower-middle-market deals never approach on their own, but a roll-up buyer’s cumulative affiliated group can. The separate transaction-size threshold under s. 110(7)-(8) started at $70,000,000 and now adjusts annually against nominal GDP, published by the Minister in the Canada Gazette — check the Bureau’s current published figure rather than assuming last year’s number still applies.
One stale belief worth correcting explicitly: the efficiencies defence that used to offset an otherwise anti-competitive merger is gone. Section 96 reads, in its entirety, “[Repealed, 2023, c. 31, s. 10].” Do not rely on secondary sources that still describe it as available.
STEP 09 OF 10
CBV Institute states plainly that its Valuation Practice Standards (100/110/120/130) “apply to independent valuation engagements beginning on or after January 1, 2026” and that the previous standards are now archived. Confirm the engagement letter for any valuation or Limited Critique work you commission cites the current standard numbers, not a report format carried over from before the changeover — a valuator working from memory of the old regime is not applying the current minimum required standard of care.
STEP 10 OF 10
A lender or co-investor financing the acquisition will want the findings from this whole guide in one place: the scoped assurance level and its limitations, the six-year records reviewed, the AR quality assessment, the s. 125 grind exposure, the GST/HST registrant confirmation, the provincial sales tax clearance status, and the employment successor exposure. Structuring the deliverable this way — rather than as a narrative memo — is what makes a Limited Critique Report from a CBV a genuinely bankable substitute for a full audit-grade engagement on a deal of this size.
A Limited Critique engagement is not a smaller version of a full quality-of-earnings review that happens to cost less — it is a different, defined level of assurance under its own CBV standard, and the engagement letter should say explicitly what work was and was not performed. Do not let a scoped report get read, internally or by a lender, as though it carries the same assurance as a full audit-grade engagement; that mismatch between what was actually delivered and what a reader assumes was delivered is where scoped reviews get their reputation for surprises.
What it reliably can do: confirm the mechanical items in Steps 2 through 8 above — records completeness, AR quality, the tax-profile grinds, GST/HST and PST exposure, and employment successor risk — each of which is a factual, checkable question rather than a judgment call about future earnings quality.
Six years of general ledgers and financial statements; six years of filed tax returns and notices of assessment; the AR and AP aging schedules for the same period, reconciled against reported revenue; GST/HST filing history and current registration status; any existing PST clearance-certificate correspondence if a prior asset transaction occurred; and the employee roster with hire dates, current compensation, and any existing severance or change-of-control obligations. Every item on that list maps to a step above — request it as one package at the start of diligence, not piecemeal as each question comes up.
That depends on the specific lender's own policy, not on anything the CBV standard itself dictates — confirm with the financing source early what level of third-party assurance they require before committing to a scope that turns out to be insufficient for their credit process.
Yes — the retention obligation runs to the corporation and its own tax filings regardless of how the sale is structured, so the same request is reasonable whether you are buying the shares or the assets.
Treat that as a finding in itself. The statutory retention obligation means a well-run target should have the records on hand; a refusal or an inability to produce them is information about how the business has been managed, not merely an administrative inconvenience.
The associated-corporation business-limit sharing specifically concerns Canadian-controlled private corporations. A non-CCPC buyer — a public company, or a foreign-controlled acquirer — does not carry this particular exposure into the target, though other tax consequences of the acquisition still need their own review.
Generally yes for the clearance-certificate mechanic itself — Saskatchewan's own bulletin states plainly that a share sale does not require one — but confirm the target itself has no unremitted PST liability sitting on its books, since that liability transfers with the corporation on a share sale regardless of the certificate question.
