Two co-founders start a company. They split shares 50/50 on day one. Eighteen months later, one founder leaves to take a corporate job. The remaining founder now has a partner who contributes nothing but owns half the company. Investors are uncomfortable. The business is frozen.

This is the problem that founder vesting solves. It is one of the most important governance mechanisms for any Ontario startup, and yet it is frequently skipped or implemented incorrectly.

This article explains how to issue founder shares properly, how vesting (and its Canadian corporate-law equivalent, reverse vesting) works, and what the mechanics look like under Ontario corporate law.

Issuing Shares: The Starting Point

Before discussing vesting, understand the basics of issuing shares in an Ontario corporation under the Ontario Business Corporations Act (OBCA).

What issuing shares actually means

When founders "receive" shares, the corporation is issuing a new security — not transferring an existing one. This requires:

The consideration for founder shares can be nominal — founders often issue shares at a fraction of a cent per share at incorporation, reflecting that the company has little value on day one. This is fine, but the board resolution and subscription should document the consideration.

Creating share classes

Most corporations start with a single class of common shares. As companies grow and bring in investors, they often create preferred share classes with different rights. Under the OBCA, creating a new share class requires amending the articles — a special resolution passed by shareholders. Plan your authorized share structure at incorporation so you have flexibility later.

What Is Founder Vesting?

Vesting is a mechanism under which a founder's ownership becomes fully theirs only over time and upon continued involvement in the company. If the founder leaves early, some or all of their unvested shares can be bought back by the corporation at a set price (usually the original issue price — often nominal).

Why it exists

Vesting exists to prevent the "cliff" problem described at the start of this article. It answers the question: "What happens to your shares if you leave?" The answer in a vested structure is: "You keep what you have earned; the rest comes back to the company."

Why investors require it

When an investor puts money into your company, they are partly betting on your continued involvement. If you could walk out the door on day two with 50% of the company's shares, the investor's bet would be badly undermined. Investors routinely require that founder shares be subject to a vesting schedule as a condition of investment — and they will require vesting as part of any term sheet.

Reverse Vesting: The Canadian Mechanism

In the United States, startup vesting is often implemented through option plans where shares are issued over time. In Canada — and particularly in Ontario — the preferred mechanism for founders is reverse vesting (also called a share buy-back agreement or founders' restricted shares agreement).

How reverse vesting works

  1. All founder shares are issued on day one (important for tax reasons — issuing at nominal value now avoids a large tax bill on shares issued at a higher value later).
  2. The corporation (and sometimes co-founders) have the right — but not the obligation — to repurchase a declining number of shares at the original issue price if the founder departs before their shares are fully vested.
  3. As time passes and vesting milestones are hit, the corporation's repurchase right expires on that tranche of shares. Those shares are now "safe" — even if the founder leaves, those shares cannot be repurchased.

Typical vesting schedule

The most common schedule is:

Accelerated vesting provisions (double trigger or single trigger) can specify that some or all remaining unvested shares vest immediately on certain events, such as an acquisition of the company followed by termination of the founder.

Documenting Founder Vesting

Reverse vesting should be documented in a standalone Founders' Share Restriction Agreement or embedded in the shareholders' agreement. Key provisions:

Tax Considerations for Founders

Because Canadian founders issue shares at nominal value before the company has significant value, there is generally no income tax on issuance. The shares are held at a low adjusted cost base.

The lifetime capital gains exemption (LCGE) may be available on the eventual sale of qualifying small business corporation shares — a significant tax incentive for Canadian founders. As of writing, the LCGE limit for qualifying shares is substantial — verify the current limit with the CRA or a tax advisor, as it is indexed annually.

To qualify, shares must meet specific conditions including the "qualified small business corporation" test. Planning for this exemption starts at the time of share issuance — it is not something you can retrofit easily.

Frequently asked questions

What if one founder does not want vesting?

Investors almost always require it. More practically, the co-founder who resists vesting is signaling they might not be fully committed — which is itself information worth having. Vesting protects everyone, including the founder who stays.

Does the repurchased shares get cancelled?

Usually yes — the corporation cancels the repurchased shares, returning the company to the pre-issuance state for that tranche. This avoids having the corporation hold its own shares indefinitely, which has its own corporate law implications.

Can vesting schedules be different for different founders?

Yes. Co-founders can have different vesting periods, cliff lengths, or acceleration triggers reflecting their different roles, contributions, and risk profiles. Document each founder's schedule clearly.

What happens to unvested shares in an acquisition?

It depends on the acquisition agreement and the vesting document. Single-trigger acceleration vests all shares on a change of control. Double-trigger acceleration vests shares only if the company is acquired AND the founder is subsequently terminated without cause. Buyers often prefer double trigger to retain founders post-acquisition.
