When people talk about two companies "merging," they often mean something different than what Ontario corporate law actually calls a merger. Amalgamation is the specific legal process under the Business Corporations Act (OBCA) for combining two or more corporations into a single amalgamated corporation. It’s not a sale, and it’s not the same as a corporation simply moving to a new jurisdiction. Understanding the difference matters, because amalgamation carries every predecessor corporation’s liabilities forward automatically — there’s no cherry-picking.
This article explains what amalgamation actually does, the general steps involved, and how it compares to the other ways businesses combine.
What Amalgamation Actually Means
Amalgamation is a statutory process: two or more existing corporations combine to form one amalgamated corporation, which then holds all the assets, rights, obligations, and liabilities that each predecessor corporation had immediately before combining. Legally, it’s treated as a continuation of each predecessor, not a purchase of one corporation by another and not a liquidation. This matters practically — unlike a share purchase, there’s no negotiating which liabilities transfer and which stay behind; everything comes along by operation of law.
Why Businesses Amalgamate
Common reasons owners and their lawyers reach for amalgamation include:
- Simplifying a group of affiliated corporations into one entity to reduce ongoing administration (fewer minute books, fewer annual filings, one set of records instead of several).
- Combining two related or previously independent businesses as part of a broader restructuring.
- Eliminating a dormant corporation by folding it into an active one, rather than formally dissolving it.
- Cleaning up structure ahead of financing or a future sale, since an outdated or fragmented corporate structure is a common source of friction in due diligence.
The General OBCA Process
- The corporations agree on terms. The directors of each amalgamating corporation approve an amalgamation agreement setting out how shares will be exchanged and what the amalgamated corporation’s articles will look like.
- Shareholders approve it. Each corporation’s shareholders must approve the amalgamation by the higher voting threshold the OBCA requires for a fundamental change like this — not simply a majority vote at a regular meeting.
- Articles of Amalgamation are filed with Ontario’s corporate registry.
- A certificate of amalgamation is issued, and the amalgamated corporation legally comes into existence at that point, combining the predecessors into one.
- Everything carries forward automatically — assets, contracts, ongoing legal proceedings, and liabilities of each predecessor become those of the amalgamated corporation without needing to be individually reassigned, the way they would in an asset sale.
The OBCA also allows a simplified process for amalgamating a parent corporation with one or more of its own wholly owned subsidiaries, which is generally more straightforward than amalgamating two unrelated corporations — a useful option for owners simply trying to collapse a group structure rather than combine separate businesses.
Amalgamation vs. Your Other Options
| Option | What Happens | Typically Used For |
|---|---|---|
| Amalgamation | Two or more corporations become one; all liabilities carry forward | Combining affiliated corporations or merging related businesses |
| Continuance | One corporation changes its jurisdiction of incorporation (e.g., from federal to Ontario) | Moving where a corporation is incorporated, not combining entities |
| Share or asset purchase | One business acquires another’s shares or assets | Acquiring an unrelated business — a separate topic from Corporate structuring, covered under Mergers & Acquisitions |
| Dissolution | A corporation formally winds up and ceases to exist | Ending a corporation with no successor entity |
What to Check Before You Amalgamate
Because liabilities carry over completely and unconditionally, amalgamation doesn’t offer the kind of "clean start" a carefully negotiated share purchase agreement might, with its representations, warranties, and indemnities. Before amalgamating, it’s worth reviewing:
- Each predecessor’s corporate records. An out-of-date minute book is a common problem that surfaces exactly when you’re trying to combine or sell a corporation.
- Contracts with change-of-control or assignment clauses. Some third-party agreements, leases, or licences may require notice or consent even for an amalgamation, depending on how they’re worded.
- Known and potential liabilities of every corporation involved, since you’re inheriting all of them, not just the ones you’re aware of today.
Frequently asked questions
Does every amalgamating corporation’s shareholders need to approve it?
Yes — each corporation involved generally needs its own shareholders to approve the amalgamation by the special voting threshold the OBCA sets for fundamental changes, not just an ordinary majority vote.
Is amalgamation the same thing as one company buying another?
No. In an amalgamation, the corporations combine into a single new legal entity by operation of law. In a purchase, one corporation continues to exist and simply acquires another’s shares or assets — a different transaction with different consequences.
Do employment contracts need to be redone after an amalgamation?
Not automatically. Because the amalgamated corporation is treated as a continuation of each predecessor, existing contracts — including employment contracts — generally continue rather than terminating, though it’s worth confirming this for your specific situation.
Can a small, dormant corporation just be amalgamated into an active one instead of dissolved?
Yes, this is a common use of amalgamation for smaller corporate groups, and it can be simpler than a formal dissolution in some cases. Both routes are available, and which one fits depends on your specific structure and goals.
