Key takeaways
  • The Ontario Business Corporations Act (OBCA) governs how Ontario corporations operate by default.
  • Share Transfer Restrictions Without a transfer restriction, any shareholder can sell their shares to anyone — a stranger, a competitor, or a creditor.
  • A shareholder agreement governs relationships among shareholders.

If you are incorporating a business in Ontario with partners, one of the first questions your lawyer will ask is: "Do you want a shareholder agreement?" The answer should almost always be yes. But understanding why requires knowing what a shareholder agreement covers — what you are actually buying when you pay a lawyer to draft one.

This article walks through the key provisions found in a well-drafted Ontario shareholder agreement, explains what each clause does, and tells you what can go wrong without one.

The Purpose of a Shareholder Agreement

The Ontario Business Corporations Act (OBCA) governs how Ontario corporations operate by default. It sets out voting thresholds, director duties, share transfer rules, and a host of other basics. The problem is that these defaults are generic — written for the median company, not yours.

A shareholder agreement is a private contract that layers over the OBCA, replacing or supplementing its default rules with ones your specific co-owners have negotiated and agreed to. Unlike articles of incorporation, a shareholder agreement is confidential.

Core Provisions in a Typical Ontario Shareholder Agreement

Share Transfer Restrictions

Without a transfer restriction, any shareholder can sell their shares to anyone — a stranger, a competitor, or a creditor. Most private shareholder agreements include a right of first refusal (ROFR): before selling to a third party, the selling shareholder must first offer the shares to the other shareholders (or the corporation) at the same price and terms. This keeps the ownership group intact.

Some agreements go further with a consent requirement: no transfer is valid unless the other shareholders approve the buyer. This is common in professional corporations or closely held family businesses.

Board Composition and Voting Rights

Who sits on the board of directors matters enormously in a corporation. A shareholder agreement can specify:

This is particularly important when two shareholder groups (say, a founder and an investor) need to be represented fairly.

Reserved Matters Requiring Unanimous Consent

Certain decisions are too significant to leave to a simple majority vote. A well-drafted agreement lists reserved matters that require unanimous (or supermajority) shareholder approval:

Minority shareholders especially benefit from reserved matters, which give them a meaningful say on high-stakes decisions.

Dividend Policy

When does the company pay dividends, and how much? Left to the default rules, the board decides entirely — a majority-controlled board can simply never declare dividends, effectively locking minority shareholders out of any return. A shareholder agreement can set out a dividend formula or a policy that dividends must be declared when free cash flow exceeds a defined threshold.

Compensation and Employment

In many small corporations, shareholders are also employees. The agreement can set salary ranges for owner-employees, establish a bonus framework, and specify what happens if one shareholder's employment is terminated. This prevents bitter disputes about why one co-owner is earning much more than another.

Non-Competition and Non-Solicitation

Most shareholder agreements include covenants that restrict departing shareholders from:

Ontario courts will enforce reasonable non-compete and non-solicit clauses, but the scope and duration must be proportionate. A lawyer should draft these carefully.

Buy-Sell Provisions

What happens when a shareholder wants out — or must get out due to death, disability, bankruptcy, or termination? Buy-sell provisions (sometimes called exit mechanisms) set out:

We cover buy-sell provisions and specific mechanisms like the shotgun clause in separate articles, but they are the beating heart of any well-structured shareholder agreement.

Dispute Resolution

Even close business partners disagree. A shareholder agreement can specify that disputes must first go to mediation before litigation is commenced, designate an arbitration process, or include a mechanism for breaking deadlocks. This keeps minor conflicts from escalating into court proceedings.

Information Rights

Minority shareholders have limited statutory rights to corporate information under the OBCA. A shareholder agreement can expand these rights — for example, requiring the corporation to provide audited financials annually, monthly management reports, or advance notice of major transactions.

Life Insurance and Funding

If a shareholder dies, the remaining owners typically need to buy out the estate — but they may not have the cash. Many agreements require each shareholder to maintain a life insurance policy on the others, with the proceeds used to fund the purchase. This is sometimes called a cross-purchase arrangement, and it is closely linked to your estate plan.

What the Agreement Does Not Cover

A shareholder agreement governs relationships among shareholders. It does not replace:

Frequently asked questions

Can a shareholder agreement override the OBCA?

In some respects, yes. The OBCA expressly permits shareholders to contract out of certain default rules. However, certain provisions — such as the right to bring an oppression remedy application — cannot be waived. A lawyer can tell you which defaults are modifiable and which are not.

How long is a typical shareholder agreement?

Length varies enormously based on complexity. A straightforward two-founder agreement might run 15 to 20 pages. A multi-class, investor-involved structure can easily reach 40 to 60 pages or more.

Should the corporation be a party to the agreement?

Yes, in most cases. The corporation signs as a party so it is bound by the provisions — for example, the restriction on issuing new shares without shareholder consent.

Can we amend the agreement later?

Yes. Shareholder agreements typically require unanimous consent to amend, so all parties must agree. Update the agreement whenever ownership changes, a new shareholder joins, or the business situation changes significantly.
