Entire Agreement Clauses and Verbal Promises of Severance in Ontario

10 Jun 2026 3 min read No comments Wrongful Dismissal & Severance Ontario
💡

If an Ontario employer verbally promises you “six months of severance” but you sign a written contract containing an ‘Entire Agreement’ clause, the court will almost always enforce the written document. This clause legally erases any prior handshake deals or verbal guarantees, meaning you must always get severance promises clearly in writing.

During the excitement of the hiring process, executives or managers will often make grand verbal promises to convince top talent to join their company. 💬 They might look you in the eye and say, “Don’t worry about the fine print; if things don’t work out, we’ll make sure you get a generous six-month severance package.”

Unfortunately, many employees later discover that their actual written employment contract contains an “Entire Agreement” clause. This aggressive legal clause specifically states that the written contract is the only valid agreement, completely wiping out any prior oral promises, emails, or handshake deals. Under Canadian law, you cannot usually enforce a verbal promise if it directly contradicts this written clause.

Step-by-Step Process in Ontario

Whether you are negotiating a new role in Hamilton, Vaughan, or Ottawa, protecting yourself from empty verbal promises is a critical step in your career. 📈 Follow these strategies to ensure you actually receive the severance you were promised.

Step 1: Identify the Entire Agreement Clause

Before signing anything, read the final pages of the contract carefully. An Entire Agreement clause usually reads something like: “This agreement constitutes the entire understanding between the parties and supersedes all prior negotiations, representations, or verbal agreements.” If this is present, any verbal guarantees of massive severance are legally dead.

Step 2: Demand Written Amendments

If the hiring manager made a verbal promise, politely request that they add a single sentence to the contract reflecting it. 🗒 For example: “In the event of termination without cause, the employee shall receive 6 months of base salary.” If the employer refuses to put their verbal promise in writing, you should assume they never intended to honour it.

Step 3: Attack the Written Termination Clause

If you were already fired and the employer is hiding behind the Entire Agreement clause, all hope is not lost. Your employment lawyer will simply ignore the verbal promise and aggressively attack the written termination clause itself. If the written clause violates the Ontario Employment Standards Act (ESA), the entire clause becomes void, and you will automatically revert to maximum common law severance.

How Much Does It Cost in Ontario?

Fighting for your proper severance package involves clear, predictable legal costs.

Legal ServiceEstimated Cost (CAD)
Pre-Employment Contract ReviewHiring a lawyer to review your contract and negotiate written severance terms usually costs between $400 and $800 CAD.
Court Filing FeeFiling a wrongful dismissal lawsuit at the Superior Court of Justice costs approximately $339 CAD.
Contingency FeesIf you sue after termination, lawyers generally charge a contingency fee of 25% to 35% of the total funds recovered.

How Long Does the Process Take?

If you catch the issue during the hiring phase, negotiating a contract amendment usually takes just 1 to 2 weeks. 🕐 However, if you are already terminated and must sue because the written contract restricted your severance, securing a negotiated settlement generally takes 3 to 6 months. Taking the matter to a full trial at an Ontario courthouse can drag on for 1.5 to 3 years.

Frequently Asked Questions (FAQ)

What is the Parol Evidence Rule?

The Parol Evidence Rule is a legal principle used by Ontario courts which states that outside evidence (like verbal promises or old emails) cannot be used to contradict or change the clear terms of a finalized, written contract. Entire Agreement clauses specifically trigger this rule.

Can I record the manager making the promise?

In Canada, you legally can secretly record a conversation you are a part of (one-party consent). However, even if you have a perfect audio recording of the promise, the judge will generally still ignore it if you later signed a contract containing an Entire Agreement clause.

What if they verbally promised severance after I signed?

If the employer makes a new, distinct verbal promise of severance during your termination meeting, that is different from a pre-employment promise. In some rare cases, this post-contract verbal agreement might be enforceable, but it is extremely difficult to prove without written evidence.

Is it bad faith to promise something verbally but not in writing?

It is certainly unethical, but courts usually expect employees to read contracts before signing. Unless the employer engaged in severe, calculated fraud or misrepresentation during the hiring process, the written contract will typically stand.
