  • A non-circumvention clause is a contractual promise that one party will not bypass another — typically an intermediary, finder, broker, or consultant — to deal directly with a contact,…
  • A well-drafted non-circumvention clause usually specifies: - Who is protected — the intermediary who made the introduction, and sometimes their affiliated entities.
  • A contract can — and often should — include all three where an intermediary is bringing forward sensitive information and valuable introductions at the same time.

Introductions are valuable, and valuable things get taken. A consultant connects a manufacturer with a distributor and expects a fee on the resulting business; a finder introduces a buyer to a company that might sell; a broker connects two parties who then quietly do a deal directly and cut the broker out entirely. A non-circumvention clause is the tool built specifically to stop the person who made the introduction from being written out of the deal it created.

This article explains what a non-circumvention clause does, how it differs from related clauses people often confuse it with, and what makes one enforceable in Ontario.

What a Non-Circumvention Clause Protects

A non-circumvention clause is a contractual promise that one party will not bypass another — typically an intermediary, finder, broker, or consultant — to deal directly with a contact, opportunity, or counterparty that the intermediary introduced, without compensating the intermediary as agreed.

It is most common in:

What the Clause Typically Requires

A well-drafted non-circumvention clause usually specifies:

Non-Circumvention vs. Non-Disclosure vs. Non-Solicitation: Don't Confuse Them

These three clauses are frequently bundled together in the same agreement (sometimes labelled an "NCNDA" — non-circumvention, non-disclosure agreement) but they protect different things.

ClauseWhat it actually protects
Non-circumventionThe intermediary's right to be compensated when a deal results from their introduction, even if the parties later try to deal "directly"
Non-disclosureConfidential information shared between the parties, regardless of whether a deal ever results
Non-solicitationA party's employees, customers, or contacts from being actively pursued by the other party for a competing purpose

A contract can — and often should — include all three where an intermediary is bringing forward sensitive information and valuable introductions at the same time.

Why These Clauses Are Sometimes Hard to Enforce

Non-circumvention clauses raise real enforceability questions that a business relying on one should understand going in:

A severability clause (addressed elsewhere in this library) is often paired with a non-circumvention clause for exactly this reason — if a court finds the scope too broad, a well-drafted severability provision gives the rest of the agreement a better chance of surviving.

Practical Checklist for a Non-Circumvention Clause

Frequently asked questions

Can I still do business with someone I met through an introduction, as long as I don't use the exact same introducer?

The clause's scope depends entirely on its wording. Some non-circumvention clauses are limited to direct dealings; others are drafted to also catch indirect arrangements designed to route around the fee. Read the specific clause before assuming any particular workaround is safe.

How is a non-circumvention clause different from just paying a finder's fee?

A finder's fee agreement sets out the payment for a successful introduction; a non-circumvention clause is what stops the party benefiting from the introduction from avoiding that payment by dealing directly with the introduced contact instead. Well-drafted referral arrangements typically include both.

What happens if someone breaches a non-circumvention clause?

The usual remedy is a claim for the fee or commission that should have been paid had the deal gone through properly, sometimes calculated by reference to what a similar transaction would have generated. Proving the breach — that the resulting deal actually stemmed from the original introduction — is often the harder part of any dispute like this.

Is a verbal understanding about not "cutting out" an introducer enforceable?

It can be, since most business agreements do not need to be in writing to be enforceable in Ontario — but proving the terms of an informal verbal understanding, including exactly what was promised and for how long, is much harder than pointing to a signed agreement. Given how much money is often at stake in these arrangements, a written non-circumvention clause is worth the modest cost of drafting one properly.
