Anonymised, illustrative composite. An internal reorganisation of a defence-adjacent supplier was textbook-exempt from ordinary Investment Canada Act review, and the exemption memo stopped one clause short of the eight words that keep national security review alive regardless.
At a glance
A multinational advanced-materials group reorganised its corporate structure: a new intermediate holding company was inserted above its Canadian operating subsidiary, by way of an amalgamation, so that the group's tax and financing structure could be rationalised ahead of an unrelated refinancing. The ultimate parent, and the individuals who ultimately controlled it, did not change. Group counsel's memo concluded, correctly, that this fell within the corporate-reorganisation exemption in the Investment Canada Act and required no net-benefit filing.
“Exempt” was the right word for Parts II through IV and the wrong word for the whole Act. Section 10(1) opens: “This Act, other than Part IV.1, does not apply in respect of” — and then lists eleven categories, including at paragraph (e) “the acquisition of control of a Canadian business by reason of an amalgamation, a merger, a consolidation or a corporate reorganization following which the ultimate direct or indirect control in fact of the Canadian business, through the ownership of voting interests, remains unchanged”. That paragraph fits this reorganisation precisely. It is the eight words at the start of the subsection — “other than Part IV.1” — that the exemption memo never reached.
The Canadian subsidiary carried assets of $190,000,000 and supplied specialty ceramic components into both civilian aerospace and defence-adjacent supply chains — the kind of sector profile that made the group's eventual national security screen substantive rather than a formality, once it happened.
Read the unit. Every exemption listed under s.10(1) — securities dealing at (a), ordinary-course venture capital at (b), realisation of security at (c), a financing acquisition with a two-year divestiture condition at (d), a control-unchanged reorganisation at (e), and the rest through to (k) — is an exemption from “this Act, other than Part IV.1”. National security review is carved out of the exemption before the list of exempted transactions even begins. A reorganisation that is textbook-exempt under (e) is, for that reason alone, not thereby exempt from Part IV.1 at all.
There is a genuine carve-back from Part IV.1 in the Act, and it is worth being precise about how narrow it is, because a memo that stops at s.10(1)(e) risks assuming the carve-back is broader than it is. Section 10(2)(b) exempts from Part IV.1 “the acquisition of control of a Canadian business by reason of an amalgamation, a merger, a consolidation or a corporate reorganization following which the ultimate direct or indirect control in fact of the Canadian business, through the ownership of voting interests, remains unchanged” — the same language as (1)(e) — but only “if the acquisition is subject to approval under the Bank Act, the Cooperative Credit Associations Act, the Insurance Companies Act or the Trust and Loan Companies Act”. That condition exists to carve back Part IV.1 for federally-regulated financial institution reorganisations specifically. An advanced-materials group's internal restructuring is not subject to approval under any of those four statutes, so s.10(2)(b) never engaged, and the general rule in s.10(1) — Part IV.1 survives — applied without exception.
Once the gap was identified, the group filed voluntarily for a national security pre-clearance rather than wait to be found. The review ran nine weeks and closed with no order issued — the reorganisation was cleared — but only after the group's counsel had to explain internally why a transaction their own memo had called exempt was undergoing a federal security review at all.
Implementing the reorganisation on the strength of the s.10(1)(e) exemption alone, without addressing Part IV.1, would not have been unlawful in itself — Part IV.1 carries no pre-clearance requirement to violate. It would, however, have left a completed reorganisation of a defence-adjacent supplier open to a national security notice at any later date, with the interim-conditions and divestiture powers addressed elsewhere in this cluster available against a transaction the parties believed, wrongly, they had put behind them.
The tell is the word “exempt” used without asking exempt from what. An ICA exemption memo that cites a paragraph of s.10(1) and stops there has answered the Parts II–IV question and left the Part IV.1 question entirely unasked — and, for a sensitive-sector reorganisation, that is very often the more consequential of the two.
