You’ve got the right co-founders, a big vision, and the energy to build something amazing. But before you split your startup’s shares equally and call it a day, there’s one crucial protection to put in place: founder vesting. Without it, your business could be exposed to major risk—especially if a co-founder walks away early but keeps their full share of ownership. Founder vesting is one of the most important legal tools early-stage companies can use to protect equity, align incentives, and prevent internal disputes. In this article, we’ll explain what founder vesting is, why it matters, how to structure it, and how to implement it in a legally sound way—particularly for Ontario and Canadian startups.

What Is Founder Vesting?

Founder vesting is a legal arrangement that ties the ownership of founder shares to time or performance milestones. Instead of receiving their full equity allocation immediately, founders “earn” their shares gradually—typically over a period of time. This protects the company if a founder (i) leaves early, (ii) fails to deliver on their responsibilities, or (iii) needs to be removed. Without vesting, a founder could walk away with a large chunk of the company—even if they only contributed for a few months.

Why Founder Vesting Is So Important

• Reduces Risk of “Dead Equity”: A co-founder who leaves early still owns a full share—even if they’re no longer contributing.
• Attracts Investors: Investors want to know the founding team is in it for the long haul. Vesting gives them that confidence.
• Keeps Founders Accountable: Equity earned over time keeps co-founders motivated to stick around and contribute.
• Supports Fairness: Vesting ensures that equity reflects actual contribution—not just early involvement.

How Does Founder Vesting Work?

🔹 Standard Vesting Schedule

• 4-year vesting period
• 1-year cliff: No shares vest until the first anniversary
• After the cliff, shares vest monthly or quarterly

Example: If a founder is granted 40% equity, they earn 10% per year over four years, starting after year one.

Simple Founder Vesting Schedule Chart

Year	Vesting Milestone	% Vested	Shares Vested (Example: 1,000 Total)
Year 1	After 1-year cliff	25%	250 shares
Year 2	Monthly or quarterly vesting	+25%	500 total shares
Year 3	Continued vesting	+25%	750 total shares
Year 4	Full vesting complete	+25%	1,000 total shares

🔹 Performance-Based Vesting

Shares vest based on milestones like launching a product, securing a major customer, achieving revenue targets.

Vesting vs. Reverse Vesting

Most Canadian startups use reverse vesting for tax reasons. Founders receive all shares up front, but the company has a right to repurchase unvested shares at nominal value if the founder leaves. This structure is typically implemented through a shareholders’ agreement or standalone vesting agreement and should include:

• Vesting schedule
• Triggering events
• Repurchase rights
• Treatment upon termination (with or without cause)

What Happens If There’s No Vesting?

• Departing co-founders can keep full equity stakes
• Less equity available for future hires or investors
• Potential deadlock on the cap table
• Investors may walk away due to messy ownership

Tip: Founder vesting is one of the most commonly overlooked—and easily avoidable—startup legal mistakes.

Where to Include Vesting Provisions

Founder vesting terms can be documented in:

• Unanimous Shareholder Agreement (USA) or general shareholder agreement
• Standalone founder vesting agreement
• Share subscription agreements or equity grant letters

Be sure these documents are signed, filed in your minute book, and updated with your cap table.

Additional Clauses to Consider

• Good leaver vs. bad leaver terms
• Acceleration clauses (e.g., partial vesting on sale)
• Termination rules for unvested shares
• Board discretion to waive or adjust vesting

Tax Considerations in Canada

Canada doesn’t allow an 83(b) election like in the U.S. That’s why reverse vesting is more common—founders avoid tax liability on share value increases. ! Important: Work with a tax lawyer or CPA. Improperly issued shares can create unexpected tax bills or disqualify you from capital gains exemptions later.

When Should You Put Vesting in Place?

At incorporation or at the time shares are issued. It’s difficult—and often contentious—to introduce vesting later if equity has already been distributed. It’s also smart to revisit vesting before:

• Raising capital
• Adding shareholders
• Issuing new shares

Conclusion

Founder vesting is one of the smartest ways to protect your startup from early exits, misalignment, and equity disputes. It ensures founders earn their equity by staying committed and contributing meaningfully.
