What is a vertical short-form amalgamation between a parent and its wholly-owned subsidiary?

A vertical short-form amalgamation is a simplified way for a parent corporation to amalgamate with one or more of its wholly-owned subsidiaries under the Business Corporations Act, without going through the full amalgamation process that independent corporations would need. Because the parent already owns all the shares of the subsidiary, there's no need to negotiate an exchange ratio, hold a full shareholder vote of outside shareholders, or give dissent rights to minority shareholders — there aren't any.

Instead, the amalgamation can generally be approved by a resolution of the directors of each corporation, rather than a special resolution of shareholders, which makes it faster and simpler to put in place. The result is a single continuing corporation that takes on all the assets, liabilities, and contracts of both predecessor corporations, exactly as a standard amalgamation would.

This structure is commonly used to simplify a corporate group, eliminate an unneeded subsidiary, or consolidate operations after an acquisition where the acquired company was folded in as a wholly-owned subsidiary before being merged into the parent. Because liabilities of both corporations become the amalgamated corporation's liabilities, it's worth confirming what obligations the subsidiary is carrying before proceeding.
