Admitting or Removing a Partner in an Ontario Partnership: Your Legal Roadmap

Businesses change. A partner wants to retire. A key employee has earned a stake. Someone's behaviour is damaging the firm. These moments are among the most legally sensitive events in any partnership's life — and how they are handled determines whether the business survives the transition intact or dissolves in a dispute.

In Ontario, admitting or removing a partner is governed first by your partnership agreement and second (where your agreement is silent) by the Partnerships Act. This article explains the legal mechanics of each, the liability implications, and the practical steps to get it done properly.

Admitting a New Partner

The Default Rule: Unanimous Consent

Under Ontario's Partnerships Act, no new partner can be admitted without the consent of all existing partners. This default rule functions as a unanimous veto — any single existing partner can block the admission. If your partnership agreement is silent on how new partners are admitted, this is the rule that applies.

This default is protective, but it can also be a bottleneck. Growing firms often benefit from modifying the rule so that, for example, a two-thirds vote of existing partners suffices to admit a new member.

What Your Agreement Should Say

A well-drafted admission clause covers:

• Who may be admitted: any person, or only persons meeting specified criteria (professional licence, capital contribution threshold, vote of partners).
• Required vote: unanimous, supermajority, or majority.
• Capital contribution: what the incoming partner must contribute and when.
• Interest received: what percentage of profits and equity the new partner receives.
• Representations: what the incoming partner confirms about their background, qualifications, and financial position.

Liability of New Partners

When someone is admitted to an existing partnership, they become personally liable for obligations incurred from the date of admission forward. They are generally not liable for debts or obligations that pre-date their joining — though prudent new partners will conduct due diligence on the firm's existing liabilities before signing on.

The Admission Agreement

Practically, admitting a new partner involves:

1. Amending the existing partnership agreement (or replacing it) to reflect the new partner's interest.
2. Signing an admission and acceptance document.
3. Updating the business name registration at ServiceOntario if required.
4. If an LLP or LP, amending the statutory declaration.
5. Notifying banks, key suppliers, and insurers of the change in partnership composition.

Voluntary Withdrawal of a Partner

A partner who chooses to leave may do so according to the terms of the partnership agreement — which should specify the notice period (commonly 60–180 days), how the departing partner's interest is valued, and the payment terms.

Calculating the Departing Partner's Interest

How much is a partner owed when they leave? The answer depends on what was agreed. Common approaches:

• Book value: the partner's capital account balance as reflected in the financial statements.
• Fair market value: an independent appraisal of the business and the partner's proportionate share.
• Formula-based: a multiple of annual profits or revenue applied to the partner's interest.

Without an agreed valuation mechanism, a departing partner and the remaining partners often end up in a dispute about what the interest is worth. This is one of the most litigated issues in partnership law. Agree on the mechanism before it is needed.

Instalments vs. Lump Sum

Paying out a large partner interest in a single lump sum can strain the business. Most partnership agreements allow the buyout to be paid over time — typically with interest on the outstanding balance. Negotiate this term at the outset, not during a contentious departure.

Removing a Partner Against Their Will

The Hard Reality Without an Agreement

The Partnerships Act contains no general right to expel a partner. Without an expulsion clause in the agreement, the only way to force a partner out who refuses to leave is to:

• Dissolve the entire partnership (which may not be the outcome anyone wants), or
• Seek a court order dissolving the partnership or buying out the difficult partner, which is expensive and slow.

This is why an expulsion clause is among the most important provisions in any partnership agreement.

Drafting an Effective Expulsion Clause

An expulsion clause typically specifies:

• Triggering events: serious breach of the partnership agreement, fraud, criminal conviction, bankruptcy, professional licence revocation, persistent neglect of duties, or conduct bringing the firm into disrepute.
• Process: written notice, an opportunity to respond, and a vote of the other partners (often unanimity or a high supermajority).
• Consequences: the expelled partner's interest is purchased at a formula price; they lose management rights immediately.

Courts scrutinize expulsion clauses carefully. They will be more likely to uphold an expulsion if the process was fair, the triggering event was clearly established, and the valuation was reasonable.

Court-Ordered Dissolution or Buyout

Even without an expulsion clause, a partner can apply to an Ontario court for a just and equitable winding-up of the partnership. Courts can also order that one partner purchase the other's interest in lieu of full dissolution. These remedies are a backstop — but they come with legal fees, delay, and uncertainty. A well-drafted agreement avoids the need for them.
