Valuing Shares on a Shareholder Buyout in Ontario: Methods, Disputes, and Fair Outcomes

When a shareholder exits a private Ontario corporation — voluntarily or otherwise — the first question is always: at what price? Getting the answer right matters enormously. Underprice the departing shareholder and you expose the remaining owners to an oppression claim. Overprice and you may saddle the surviving business with crippling debt.

Valuing shares in a privately held company is part science, part professional judgment, and — without a prior agreement — often the most contentious part of any shareholder departure. This article explains the main approaches used in Ontario, how shareholder agreements address valuation in advance, and what happens when co-owners cannot agree.

Why Private Company Shares Are Hard to Value

Public company shares have a market price, updated by the second. Private company shares have no public market — their value must be estimated by applying recognized valuation methods to the company's financial information.

Different methods produce different results. A company with low earnings but significant assets will look more valuable under a net-asset approach than a multiple-of-earnings approach. A fast-growing service business with few tangible assets may look more valuable under an earnings approach than a balance-sheet one.

This is not a problem with the methods — it is a feature of the complexity of business value. It is also why agreeing on the valuation method in advance, in the shareholder agreement, is so important.

Common Valuation Methods

1. Adjusted Book Value (Net Asset Value)

The adjusted book value method starts with the corporation's balance sheet — total assets minus total liabilities — and adjusts the assets and liabilities to their fair market values where they differ from book (accounting) values.

• Best for: asset-heavy businesses (real estate holding companies, equipment-intensive businesses, investment holding companies)
• Weakness: understates value for profitable service businesses, where goodwill and earning capacity are the primary source of value

2. Multiple of Earnings (Capitalized Earnings)

This approach takes a measure of the company's earnings — often EBITDA (earnings before interest, taxes, depreciation, and amortization), or sometimes EBIT or net income — and multiplies it by a factor that reflects how the market values comparable businesses.

For example, a business generating $500,000 of annual EBITDA, valued at a 4x multiple, would be worth $2 million at the enterprise level. The equity value would then be adjusted downward by the amount of any debt.

• Best for: profitable operating businesses where earnings are the primary value driver
• Weakness: requires judgment on the "right" multiple, which varies by industry, size, risk, and market conditions

The multiple used should be verified against comparable transactions in the industry — as of writing, multiples vary widely by sector, so verifying current market data with a professional is essential.

3. Discounted Cash Flow (DCF)

DCF is a more sophisticated version of the earnings approach. It projects the business's future free cash flows over a defined period and discounts them to present value using a discount rate that reflects the risk of the business. A terminal value captures the value of cash flows beyond the projection period.

• Best for: businesses with predictable, long-term cash flows; also used when the company is expected to change significantly in coming years
• Weakness: highly sensitive to assumptions about growth, margins, and discount rates — small changes in inputs produce large changes in value

4. Agreed Value (Specified in the Agreement)

Some shareholder agreements take the valuation question entirely off the table: the shareholders agree on a price (or formula) when drafting the agreement, and update it regularly.

Common approaches:

• Annual agreed value: the shareholders sign an annual certificate setting the per-share value; that value governs any buyout triggered in the following year
• Formula value: the price is calculated by applying a pre-agreed formula (e.g., 4x trailing-twelve-months EBITDA minus net debt) at the time of the triggering event

The weakness of the agreed-value approach is that it requires discipline — shareholders must remember and agree to update the valuation, and relationships that are already strained may make this impossible in practice.

5. Independent Business Valuation

If the parties cannot agree — either because no valuation mechanism was specified, or because the agreed process has broken down — they often turn to an independent business valuator (IBV). In Canada, the CBV Institute certifies professionals with the Chartered Business Valuator (CBV) designation. These professionals apply recognized valuation methods and produce an opinion of fair market value.

Shareholder agreements often specify how an IBV is engaged when needed:

• Each party appoints an IBV, and the two valuators agree on a result or appoint a third as an umpire
• The parties jointly appoint a single IBV from an agreed list
• One party proposes a valuator, and the other must accept or replace within a set period

Cost and timeline should be addressed: who pays for the valuator, and does each party pay for its own?

What "Fair Market Value" Means in Ontario

In Canadian legal and tax practice, fair market value is typically defined as the highest price available in an open and unrestricted market, between a willing buyer and a willing seller who are knowledgeable, prudent, and acting at arm's length. This definition comes from the tax context but is widely used in shareholder disputes and estate matters.

A few important consequences:

• Fair market value is not what the departing shareholder needs — it is what a hypothetical buyer would pay
• A minority discount may be applied if the shares carry less than a controlling interest and the shareholder agreement does not expressly exclude such a discount
• Strategic or synergy value that a specific buyer might pay is generally excluded

Shareholder agreements can (and often do) specify that the buyout price will be on a no-minority-discount basis, which protects minority shareholders from receiving artificially reduced proceeds on exit.

What the OBCA Provides for Dissenting Shareholders

The OBCA gives shareholders who oppose certain fundamental corporate changes (such as amalgamations or asset sales) a dissent and appraisal right: the right to be paid the fair value of their shares. Fair value in this context is a distinct legal concept that may or may not equal fair market value — generally, courts under the OBCA do not apply minority discounts in dissent proceedings.

This statutory remedy operates independently of any shareholder agreement but is an important backstop for shareholders who disagree with major corporate decisions.
