  • An Ontario Business Corporations Act (OBCA) corporation's articles typically state, in one form or another, what business the corporation is authorized to carry on.
  • - A lender or investor wants comfort that the corporation's funds will only be used within a defined scope of activity - Founders want to formally separate one line of business from…
  • - The business has genuinely diversified beyond what the original, narrower articles contemplated - A restriction inherited from an older template is now getting in the way of a new line…

Most business owners incorporating in Ontario today do not think much about whether their corporation's articles limit the kind of business it can carry on — the modern default is usually broad and unrestricted. But restrictions do still show up, sometimes deliberately (a lender or investor wants a narrow, focused mandate) and sometimes as a leftover from an older template. Either way, changing that restriction later requires a formal step, not just an internal decision.

This article walks through business restrictions in an Ontario corporation's articles: what they mean, why they get added or removed, and the general process to amend them.

Restricted vs Unrestricted: What Your Articles Currently Say

An Ontario Business Corporations Act (OBCA) corporation's articles typically state, in one form or another, what business the corporation is authorized to carry on. In practice this usually falls into one of two patterns:

Check your own articles rather than assuming — many business owners have never actually read the business-purpose clause in their founding document.

Why a Corporation Might Want to Add a Restriction

Why a Corporation Might Want to Remove a Restriction

The Amendment Process

  1. Confirm exactly what your current articles say about business purpose — do not rely on memory or an assumption about what a "standard" incorporation includes.
  2. Decide on the precise new wording, whether that is broadening to an unrestricted purpose or adding a specific, narrower restriction.
  3. Pass a directors' resolution proposing the amendment.
  4. Obtain shareholder approval. Amending the articles of an OBCA corporation generally requires a special resolution of the shareholders — a higher voting threshold than ordinary business, commonly understood as at least two-thirds of votes cast. Confirm any additional requirement in your articles or a unanimous shareholder agreement.
  5. File Articles of Amendment through the Ontario Business Registry, along with the applicable filing fee.
  6. Update the minute book and confirm the amendment is reflected anywhere else the corporation's stated purpose matters.

What Changes Automatically vs What You Must Update Separately

Amending the articles changes the corporation's legal business-purpose clause going forward, but it does not automatically:

Each of these needs to be reviewed and, where necessary, updated on its own.

Frequently asked questions

Do most small businesses actually need a restricted purpose?

No — most small and mid-sized Ontario businesses operate perfectly well with an unrestricted purpose clause, which avoids having to amend the articles every time the business adds a new activity. A restriction is usually there for a specific reason, such as a lender or investor requirement.

Can we remove a restriction without shareholder approval if all the directors agree?

No — amending the articles is a shareholder-level decision under the OBCA, not something the directors can approve on their own, regardless of how aligned the board is.

Will removing a restriction affect our existing contracts?

Generally not automatically, but it is worth reviewing any material contracts, especially loan agreements, that were negotiated with the restriction in mind, since a lender may have relied on that limitation when extending credit.

How long does an amendment like this typically take?

Processing depends on the filing method and current government service levels, which vary and change; confirm the current expected turnaround with the Ontario Business Registry or your lawyer rather than relying on a fixed number.
