Not every path to owning part of an Ontario business starts with writing a cheque for shares. An earn-in lets someone — often an employee, a junior partner, or a family member being groomed to take over — build up an ownership stake over time by meeting agreed milestones, rather than paying the full price upfront. It's a common structure where the incoming owner has more relevant time and effort to contribute than immediate cash.

This article explains what an earn-in actually is, how it's usually structured, and how it differs from simply buying shares outright.

Earn-In, Defined

An earn-in is an arrangement where a person acquires equity in a business gradually, in exchange for meeting specified conditions over a defined period — commonly continued employment or service, hitting performance or revenue targets, or making staged capital contributions. Instead of one transaction transferring full ownership on day one, ownership builds up, or "vests," as the person delivers on what the agreement requires.

Earn-ins show up most often in:

How an Earn-In Typically Works

  1. The parties agree on the end state. What percentage of ownership is the person working toward, and over what general period?
  2. Milestones are set. These might be tied to time — continued service for a set number of years — performance, or a combination of both.
  3. An interim arrangement covers the earn-in period. The incoming owner might receive a profit-sharing right, a bonus tied to performance, or a small initial minority stake before the rest is earned.
  4. Shares, or an equivalent interest, vest as milestones are met. Vesting can be structured to happen gradually over time or in defined tranches tied to specific achievements.
  5. A final mechanism completes the transfer. Once fully earned, the arrangement typically converts into an actual share purchase, share issuance, or transfer completing the ownership transition.

Common Ways Earn-Ins Are Structured

What an Earn-In Needs to Address in Writing

None of this happens automatically — it needs its own written agreement, layered together with, or built into, the business's shareholders agreement.

Frequently asked questions

Is an earn-in the same as being paid in shares instead of salary?

Not exactly. An earn-in is usually structured as a path to genuine ownership tied to specific conditions, rather than compensation paid in share form. The distinction matters for tax and legal treatment, so it needs to be documented precisely rather than assumed.

What happens to an earn-in if the business is sold to someone else partway through?

This depends entirely on what the earn-in agreement says. Well-drafted agreements address what happens on a sale, change of control, or early exit — if yours doesn't, that's a gap worth fixing before it becomes a dispute.

Can an earn-in be reversed if the person doesn't meet the milestones?

Generally yes — because ownership only vests as milestones are met, an earn-in that stalls typically just stays incomplete, rather than requiring the business to buy back shares that were never fully transferred. The specifics depend on how the agreement is drafted.

Do earn-ins need to be registered with the corporation the same way a share purchase does?

Any actual share issuance or transfer that occurs, including partial vesting tranches, still needs to be properly documented and reflected in the corporation's minute book and share registers, the same as any other share transaction.
