What triggers a Competition Act pre-merger notification?

Two different sections, and a proposed transaction has to clear both of them before notification is required at all.

Short answer

A conjunctive test — you need both halves. The parties (with affiliates) must clear the party-size threshold in s.109 of the Competition Act, enacted at $400 million in Canadian assets or Canada-sourced gross revenues, and the transaction itself must separately clear a size-or-percentage threshold in s.110, measured differently for an asset deal, a share deal, an amalgamation, or a non-corporate combination. Clearing one test without the other means the transaction is not notifiable.

Two different tests, and both have to be crossed

Section 109(1) sets the party-size floor: parties, “together with their affiliates … have assets in Canada that exceed four hundred million dollars in aggregate value … or … had gross revenues from sales in, from or into Canada … that exceed four hundred million dollars.” Section 110(1) then narrows which transactions are caught at all: “This Part applies only in respect of proposed transactions described in this section.” An asset deal is measured under s.110(2), a share deal under s.110(3), and each has its own dollar figure, enacted at $70,000,000 under s.110(7) and re-indexed annually under s.110(8) — check the current prescribed amount before relying on either the $400 million or $70 million figure.

An amalgamation needs two qualifying entities, not one

Section 110(4) tests the size of the surviving, post-amalgamation entity. But s.110(4.1) adds a separate condition that is easy to miss on a first read: “This Part does not apply in respect of a proposed amalgamation of two or more entities … unless each of at least two of the amalgamating entities, together with its affiliates … has assets in Canada … that exceed in aggregate value the amount determined under subsection (7) or (8) … or (b) has gross revenues … that exceed in aggregate value the amount …” A continuing entity that looks obviously large enough is not notifiable if only one of the entities going into the amalgamation independently clears that bar.

The share test layers a voting-percentage threshold on top of the dollar test

Section 110(3)(b) requires that the acquirer, after closing, would own voting shares carrying “more than the following percentages of the votes …: (i) 20%, if any of the corporation's voting shares are publicly traded, (ii) 35%, if none … are publicly traded, or (iii) 50%, if the person or persons already own more than the percentage set out … before the proposed acquisition.” Clearing the dollar test alone does not trigger notification on a share deal — the acquirer also has to be crossing one of those three percentage lines.

The Canadian benchmark

What do businesses like this one actually sell for?

Canadian small-business transaction data is not published anywhere, so most valuations in this country quote an American benchmark. The Deavo–Treadstone Acquisition Index is a daily record of Canadian listings built to replace that: asking-price distributions by province and city are published now, and days on market, departure rates and asking-to-sale spreads follow as the series lengthens.
