Can I assess a termination clause by reading just one sentence?
A historical Osler case analysis illustrates why the complete clause and service history matter.

What the historical case shows
Osler’s July 2018 analysis describes Amberber v. IBM Canada Ltd., 2018 ONCA 571, a decision of the Ontario Court of Appeal. In that case, the Court upheld a termination clause after reading it as a whole, rather than splitting it into separate parts. The firm represented IBM and presents an employer-side perspective. This result does not validate a similar sentence in another contract, and later case law may affect how a clause is assessed today. The case is best used as a lesson in how to read a termination clause, not as a guarantee that any particular wording will be enforced.
Keep the complete clause and its context
To assess a termination clause, you need the signed offer letter, any incorporated policies, amendments, and notices. Read the entire clause, including any language about statutory minimums, benefits, and the payment formula. Also read adjacent provisions that may affect how the clause operates. A screenshot of one sentence can omit wording that an adviser needs to see. For example, a clause may state that the employee receives the greater of a formula amount or the amount required under the Employment Standards Act, 2000. That formula may depend on a service reference date, so you must also know which date the employer used.
Check the employment history
List your actual start dates, changes of employer and written recognition of prior service. Ask which date payroll used and which date the termination offer uses. A discrepancy deserves a question; it does not establish that the entire clause is void or that a particular amount is due. Keep documents recording any transfer and service recognition together, so an adviser can compare the contract’s formula with the employer’s calculation.
Hypothetical illustration: one sentence is not the whole clause
Imagine an employee has a screenshot of a payment formula but not the sentence that follows it about statutory minimums. The preparation step is to obtain the complete signed clause and related provisions, identify the service date used and request the employer’s calculation. Ask a current Ontario adviser to assess the entire wording and later case law. This is an original illustration of document preparation, not a new report of Amberber or a conclusion that a similar formula is valid.
Questions to ask a current Ontario adviser
If you are in Ontario and need to assess a termination clause, prepare questions such as: Does this clause, read as a whole, comply with the Employment Standards Act, 2000? Does it clearly displace the common law presumption of reasonable notice? Is there any ambiguity that a court would find reasonable? What later court decisions might affect this clause? Bring the complete signed agreement, any amendments, and a written summary of your service dates. A specialist can then apply current law to your specific facts.
Next steps if the issue is unresolved
If you cannot determine whether a clause is enforceable, or if your employer’s calculation differs from what you understand, do not assume the clause is void or that you must resign. Instead, seek advice from an employment lawyer in your jurisdiction. Provide the lawyer with the complete clause, your service history, and any correspondence about the termination. The lawyer can explain how a court would likely interpret the clause and what options you have. This article does not provide legal advice for your specific situation.
