An amalgamation needs two qualifying entities, not one

Anonymised, illustrative composite. A national HVAC-services roll-up amalgamated its existing platform with a small regional bolt-on. On a plain reading of the continuing entity’s size, the deal looked obviously notifiable — until counsel read the very next subsection.

At a glance

  • • Ontario, second-stage amalgamation of an existing national HVAC-services platform (“Platform Co”) with a newly acquired regional bolt-on (“Target Co”).
  • • Platform Co: Canadian assets $340M, Canadian gross revenue $265M — both well over the Competition Act’s prescribed transaction-size amount on their own.
  • • Target Co: Canadian assets $9.4M, Canadian gross revenue $14.2M — well under the threshold on its own.
  • • Competition Act s.110(4) tests the CONTINUING entity that results from an amalgamation — here, combined assets of roughly $349M, clearing the threshold easily.
  • • But s.110(4.1) is a limit on that test: Part IX does not apply unless at least TWO of the amalgamating entities independently clear the threshold. Only Platform Co did — so the amalgamation was exempt.

The situation

A private-equity-backed national HVAC-services roll-up had, over several years, assembled a large operating platform — call it Platform Co — with Canadian assets of $340M and Canadian gross revenue of $265M. It had just closed a share purchase of a small regional maintenance company, Target Co, with Canadian assets of $9.4M and Canadian gross revenue of $14.2M. As a routine second-stage integration step — unifying insurance, banking and tax filings — counsel proposed amalgamating Target Co directly into Platform Co.

The problem

Before drafting the amalgamation agreement, the deal team ran the standard Competition Act screening check the firm used for every transaction: measure the parties against the notification thresholds. Because this second step was itself a proposed transaction under Part IX of the Act, it needed its own analysis, separate from whatever had applied to the original share purchase.

The number that jumped out was the size of the CONTINUING entity — the company that would exist after the amalgamation, essentially Platform Co with Target Co folded in: roughly $349M of combined Canadian assets. On the deal team’s first read of s.110(4), that looked clearly notifiable, and the associate budgeted five weeks into the closing timeline for a Competition Bureau filing and waiting period neither side had planned for on a routine internal restructuring.

The numbers

Platform Co alone: $340M in Canadian assets, $265M in Canadian gross revenue — both, on their own, well above the Act’s prescribed transaction-size amount. Target Co alone: $9.4M in assets, $14.2M in revenue — both well below it. The continuing entity after amalgamation: roughly $349M in combined assets, the figure that triggered the initial notification concern.

The rule that decided it

Amalgamations are tested differently from an ordinary asset or share acquisition, and that difference is the whole story. Section 110(4) provides that “this Part applies in respect of a proposed amalgamation of two or more entities if one or more of those entities carries on an operating business, or controls an entity that carries on an operating business, and if (a) the aggregate value of the assets in Canada…that would be owned by the continuing entity that would result from the amalgamation…would exceed the amount set out in subsection (7) or the amount determined under subsection (8).” Unlike a share purchase, which is tested against the target alone, this test looks at what the deal PRODUCES — which means an amalgamation between anyone and an already-large existing platform will almost always clear this threshold, no matter how small the other party is.

That is exactly the outcome s.110(4.1) exists to prevent. It is headed “General limit — parties to amalgamation,” and it reads: “This Part does not apply in respect of a proposed amalgamation of two or more entities if one or more of those entities carries on an operating business or controls an entity that carries on an operating business, unless each of at least two of the amalgamating entities, together with its affiliates, (a) has assets in Canada…that exceed in aggregate value the amount determined under subsection (7) or (8)…or (b) has gross revenues from sales in, from or into Canada…that exceed in aggregate value the amount determined under subsection (7) or (8).”

Read the unit. Subsection (4.1) is not a second, independent test running alongside (4) — it is a LIMIT on it, and it is expressed as a negative: Part IX does not apply AT ALL unless at least two amalgamating entities independently clear the threshold. Platform Co did, on its own. Target Co did not, on its own, come close. With only one of the two entities qualifying, s.110(4.1) means Part IX simply does not apply to this amalgamation — regardless of how large the resulting continuing entity is.

The outcome

Once the associate re-read s.110(4.1) as a qualifier rather than a second freestanding test, the conclusion reversed: no notification, no filing, no statutory waiting period. The amalgamation proceeded on the original timeline, roughly five weeks earlier than the team had just finished budgeting for, with a short memo on file recording the s.110(4.1) analysis in case the question ever came up again on a future bolt-on.

What it would have cost otherwise

Filing a notification that was never required would not just have cost the filing fee and the time to prepare it — it would have run the transaction through the Act’s waiting period under s.114(1), which requires notice and the prescribed information to be given before the transaction is completed. That is real delay for a routine internal restructuring with no competitive overlap of any kind between an HVAC platform and a small regional maintenance shop it had already acquired.

The tell

The initial misread was not careless — s.110(4) and s.110(4.1) are adjacent, and (4.1) reads, on a fast pass, like it could be an additional way Part IX gets engaged rather than a way it gets switched off. The marginal note is the tell: “General limit,” not “Additional application.” A provision immediately following the test it modifies is worth reading as a modifier before being read as a second test.

Takeaways

  • • Competition Act s.110(4) tests an amalgamation against the CONTINUING entity’s size — not against either amalgamating party alone, which is why pairing with an existing large platform almost always looks notifiable on a first read.
  • • s.110(4.1) is a LIMIT on that test: Part IX does not apply unless at least two of the amalgamating entities independently clear the threshold on their own assets or revenues.
  • • A large-and-small amalgamation can be exempt from notification even when the resulting continuing entity is far over the threshold, because only one party qualifies.
  • • Contrast with a hybrid asset-and-share deal, where s.110(3.1) runs the arithmetic the other direction — aggregating two legs that are each too small alone into a notifiable whole.
  • • Read a provision headed “General limit” as a qualifier on the section before it, not as an independent basis for a different conclusion.

  • • Competition Act, R.S.C. 1985, c. C-34, s.110(4) — notification test for a proposed amalgamation, keyed to the continuing entity’s size.
  • • s.110(4.1) — the general limit requiring at least two amalgamating entities to independently exceed the transaction-size amount.
  • • s.114(1) — the pre-completion notification requirement and waiting period that would have applied had the amalgamation been notifiable.
  • • Not asserted here: the current dollar transaction-size amount under s.110(7)/(8), which is indexed annually and was not independently verified for this file. The mechanic described does not depend on its exact value.
