How to Write a Grievance in Canada
The anatomy of a well-drafted grievance, the mistakes that weaken a case, and how AI can prepare a first draft in minutes.
The anatomy of a well-written grievance
A grievance is a legal document. It is the first record an arbitrator will read if the case is not resolved at an earlier step, and everything that follows — the employer's response, the union's reply, disclosure, witness preparation — is framed by how the grievance was drafted. Canadian arbitrators generally take a liberal approach to grievance interpretation, but a clearly written grievance still does more work for the grievor than a vague one.
A well-drafted Canadian grievance typically contains:
- The parties.The grievor's name, job title, department, employee number, and bargaining unit. For policy or union grievances, identify the union as the grievor.
- The dates. Both the date of the incident (or the date the grievor became aware of it) and the date the grievance is being filed. These drive the arbitrability analysis.
- The articles alleged to be violated.Cite specific articles of the collective agreement — not a general reference to “the agreement.” Include any legislation engaged (human rights code, employment standards, occupational health and safety).
- Statement of facts. A chronological, neutral description of what happened. Who did what, when, and where. Avoid editorial language and stick to observable facts.
- Remedy sought.What the grievor wants — reinstatement, compensation, a cease-and-desist order, a declaration, or a policy change. Ask for “and such further and other remedy as the arbitrator deems just” to preserve flexibility.
- Signatures and step.The grievor's signature, the union representative's signature, the date, and the step of the grievance procedure being filed.
The common mistakes
Most weaknesses in a grievance are introduced at the drafting stage, not at arbitration. The recurring problems we see in Canadian locals are the same year after year:
- Generic article citations. “Violation of the collective agreement” invites a preliminary objection and forces the union to amend later. Name the specific articles in play at the outset.
- Vague or argumentative facts.“The employer has been harassing the grievor for months” is a conclusion, not a fact. List the incidents, dates, and witnesses.
- Missing remedy. A grievance without a remedy leaves the arbitrator guessing what the grievor wants. Be specific about make-whole relief, interest, and costs.
- Missed deadlines.The single most common reason grievances are dismissed at a preliminary stage. Track the agreement's time limits from the day the grievor becomes aware of the incident.
- Filing at the wrong step. Each collective agreement sets out which issues start at which step. A policy grievance filed at step 1 instead of step 2 creates avoidable procedural arguments.
The AI shortcut
Writing a grievance from a blank page is the slowest possible starting point. A steward usually has a set of facts, a rough sense of which articles are engaged, and a few days to get something filed. Everything else — mapping the facts to the agreement, drafting the statement of facts, proposing a remedy — is recurring work that can be automated.
Sertus reads the collective agreement and the facts of the case, and produces a first-pass grievance draft that cites the specific articles engaged, lays out the facts in a neutral chronological form, and proposes a remedy grounded in what Canadian arbitrators typically order for that kind of violation. The steward then edits the draft — because the human is still the author — but starts from a structured document instead of a blank page.
Sertus is built by the co-author of Canadian Labour Arbitration(Brown & Beatty), the reference text Canadian arbitrators cite, so the drafting is grounded in the framework arbitrators actually apply. Sertus does not provide legal advice; consult counsel for any matter requiring a legal opinion.
