Using Amalgamation to Acquire a Business in Ontario: The Basic Concept

When most people think about buying a business, they picture two structures: a share purchase or an asset purchase. There is a third route that comes up more often than people expect, especially once two corporations already have some relationship to each other — amalgamation.

Amalgamation is a statutory process under Ontario's Business Corporations Act (or the federal Canada Business Corporations Act, for federally incorporated companies) that lets two or more corporations combine into one continuing corporation. Instead of one company buying another's shares or assets, both corporations legally merge. Used deliberately, amalgamation can be a genuine amalgamation acquisition tool — not just a housekeeping step after a deal has already closed.

This article explains what amalgamation actually does, how it differs from a conventional purchase, and why a buyer or seller might reach for it.

What Amalgamation Actually Does

Amalgamation is not one company absorbing another the way a purchase does. Under the OBCA, two or more corporations amalgamate to continue as a single corporation. The resulting corporation is generally treated as a continuation of each of the predecessor corporations — it carries forward their property, their contracts, and their obligations, rather than starting fresh.

That continuity is the key feature that distinguishes amalgamation from a purchase:

• In an asset purchase, the buyer picks specific assets and specifically assumed liabilities; everything else stays behind with the seller.
• In a share purchase, the buyer acquires the target's shares, and the target corporation keeps existing as a subsidiary, carrying everything it always had.
• In an amalgamation, the corporations combine into one entity going forward — there is no separate "target" left standing afterward, and no separate "buyer" shell holding shares of it (unless the amalgamation is structured that way deliberately, as in a triangular amalgamation).

Why a Buyer Might Choose Amalgamation Over a Purchase

Amalgamation is used as an acquisition tool in a few recurring situations:

1. Simplifying a corporate group after a purchase. A buyer often purchases shares first, then amalgamates the target with its own holding company or with a subsidiary, to eliminate a redundant corporate layer and simplify future financing, accounting, and tax filings.
2. Combining two businesses that will operate as one going forward. Where the commercial goal is genuinely to merge operations — not to keep the acquired business as a separate subsidiary — amalgamation can achieve that directly, without a separate wind-up or asset-transfer step later.
3. Structuring around financing or tax objectives. Certain financing and tax outcomes are easier to achieve when the acquired business and the acquirer's existing operations sit inside one corporation rather than a parent-subsidiary pair. Whether that applies to your deal depends heavily on the specific numbers and should be reviewed with an accountant.

The Basic Process, in Outline

The mechanics vary depending on which amalgamation procedure applies (a separate topic worth its own read), but at a high level, an OBCA amalgamation generally involves:

• [ ] Each amalgamating corporation's directors approving an amalgamation agreement setting out the terms of the combination
• [ ] Shareholder approval of the amalgamation (by special resolution), unless a simplified short-form procedure is available
• [ ] Filing articles of amalgamation with the Ontario government to bring the amalgamated corporation into existence
• [ ] Addressing dissenting shareholders, if any, who oppose the amalgamation
• [ ] Dealing with creditors, landlords, and counterparties whose contracts may require notice or consent on a change of corporate structure

Because the amalgamated corporation is treated as a continuation of both predecessors, due diligence has to cover both corporations fully — you cannot ring-fence liability the way you can in an asset purchase.

Amalgamation Is Not a Shortcut Around Diligence

A common misconception is that amalgamating is a lighter-touch way to combine businesses than a formal purchase agreement. It isn't. Because the surviving corporation inherits the full liability history of every predecessor, a buyer using amalgamation as an acquisition tool needs the same due diligence — corporate records, contracts, litigation history, employee obligations, tax compliance — that a share purchase would demand, plus care around the amalgamation agreement itself and any shareholders who might dissent.
