Most small Canadian businesses arrive at a sale with financial statements prepared on a notice-to-reader basis. Knowing what that phrase actually means — and does not mean — changes how much weight a buyer can put on the numbers.
Key takeaways
A notice-to-reader, or compilation, engagement is the accountant compiling the client’s own figures into a standard financial statement format, without independently testing, verifying, or forming any opinion on whether those figures are accurate. It is the lowest of the recognized levels of accountant involvement in Canadian financial reporting — below a review engagement, and well below a statutory audit — and the label exists precisely to signal to anyone reading the statements that no assurance of any kind is attached to the numbers inside them.
Canada’s clearest published illustration of how these levels scale is not written for a private acquisition, but the logic transfers directly. The federal Not-for-profit Corporations Act sets the requirement by revenue: a soliciting corporation with revenue of $50,000 or less needs “only a compilation” if no public accountant is appointed at all; between $50,000 and $250,000 the appointed accountant “must conduct an audit,” downgradable to a review only by special resolution; above $250,000, “PA must conduct an audit” with no downgrade option. (ised-isde.canada.ca) A compilation sits at the bottom of that ladder by design — it is what happens when nobody has required anything more.
A compilation provides no testing of revenue recognition, no verification that reported sales tie to bank deposits, no confirmation that receivables are collectible, and no opinion on whether the figures conform to any particular accounting framework. The accountant has taken the client’s numbers and formatted them; the accountant has not checked them. That is not a criticism of the engagement — it is simply what the “notice to reader” label is legally signalling, and it is why a buyer relying on notice-to-reader statements alone is, in effect, relying entirely on the seller’s own bookkeeping with no independent check on any of it.
This is precisely the gap deavo’s guide to reading financial statements before a purchase is describing when it lists its red flags: owner compensation and personal expenses run through the business, one-time items such as “a lawsuit settlement or a one-off equipment sale,” related-party pricing “including rent paid to a property the owner also owns,” and a gap between the statements and what was actually filed with the CRA or for GST/HST. (deavo.ai) None of those items would necessarily be caught, or even noticed, by a compilation engagement — catching them is diligence work the buyer has to commission separately, not something the notice-to-reader statements already did.
The same deavo guide makes a point worth carrying forward specifically: “Two accountants reviewing the same books can reasonably normalize a few borderline items differently” — which is exactly what a compilation, with no independent testing standard behind it, allows to happen. (deavo.ai) The practical response is not to distrust every compiled statement, but to ask how consistently the seller’s own add-backs and classifications have been applied year to year, since a business whose treatment of the same line items shifts from year to year on a notice-to-reader basis has no independent check flagging the inconsistency the way a review or audit engagement would.
Moving from a compilation to a review engagement, and from a review to a full audit, brings progressively more independent testing — the review involves analytical procedures and inquiry, the audit involves substantive testing of underlying transactions and balances. The Not-for-profit Corporations Act grid shows the trigger clearly at the review-to-audit boundary: a soliciting corporation between $50,000 and $250,000 in revenue defaults to an audit and needs a special resolution to step down to a review instead. (ised-isde.canada.ca) Most privately held small and mid-market Canadian businesses being sold have never had a reason to commission anything beyond a compilation — there is no shareholder base requiring it, and no regulator mandating it — which is exactly why the burden of independent testing on a sale falls on the buyer’s own diligence rather than on statements the seller already has in hand.
A quality of earnings report is not itself a formal review or audit engagement, but it fills the specific gap a notice-to-reader statement leaves open. Treadstone Law describes it as testing whether “reported results reflect sustainable, recurring earnings, rather than one-time gains, unusual accounting treatments, or temporary factors” — precisely the testing a compilation was never designed to perform. (treadstonelaw.ca) Commissioning one is, in effect, how a buyer converts notice-to-reader statements into something with real, transaction-specific scrutiny behind it, without necessarily needing to commission a full historical audit of a business that has never had one.
A target arrives at diligence with three years of notice-to-reader statements showing steadily growing net income, prepared by the same local accounting firm each year. Taken at face value, the trend looks clean. Applying deavo’s consistency test, the buyer asks the accountant directly how a specific recurring add-back — the owner’s vehicle lease — was treated across the three years, and learns it was added back to earnings in years one and two but, following a change in the owner’s personal arrangements, was not added back in year three, because the vehicle had already been moved off the company’s books. On paper this looks like a $14,000 improvement in reported profitability in year three; in substance it is an accounting presentation change, not an operating improvement. Because a compilation engagement performs no testing that would surface this on its own, the inconsistency only came to light because the buyer asked the specific question — exactly the gap a notice-to-reader statement, by definition, leaves for diligence to fill.

No. It means no independent testing has been performed on them, which is a different statement entirely. deavo’s own guidance is explicit that none of the red flags it describes “signal on their own that a business is a bad opportunity” — the point is that a compilation gives a buyer no independent basis to rule problems in or out. (deavo.ai)
No, and the distinction is not one of scale — it is a different engagement type entirely, with no testing, verification or opinion attached. The federal Not-for-profit Corporations Act illustrates how the levels are formally distinguished by revenue and required procedure, even though that particular grid governs a different kind of entity. (ised-isde.canada.ca)
Not necessarily. A quality of earnings review, scoped to the transaction, is the more common route — it tests the specific claims a buyer needs tested, described by treadstonelaw as evaluating whether results reflect “sustainable, recurring earnings,” without requiring the seller to commission a historical audit it has never had a reason to prepare. (treadstonelaw.ca)
A short call is enough to scope the testing that fills the gap a compilation leaves open.
