Filing a Grievance Against Your Union for Failure to Represent in Ontario

9 Jun 2026 6 min read No comments Work & Employment Rights Ontario

If you are a unionized employee in Ontario and your union unfairly refuses to file a grievance after you are wrongfully terminated or disciplined, you can file a Duty of Fair Representation (DFR) complaint with the Ontario Labour Relations Board (OLRB). You must prove the union acted in a manner that was arbitrary, discriminatory, or in bad faith.

Understanding the Duty of Fair Representation in Ontario

Working in a unionized environment in Ontario provides incredible job security. When you pay your monthly union dues in cities like Toronto, Windsor, or Sudbury, you expect your union stewards and representatives to fight for you when management crosses the line. But what happens when the union turns its back on you? What if they refuse to file a grievance after you are unjustly fired, or they completely ignore your phone calls?

Under Section 74 of the Ontario Labour Relations Act (OLRA), every certified trade union owes its members a strict “Duty of Fair Representation” (DFR). 📑 This legal duty mandates that the union cannot represent its members in a way that is arbitrary, discriminatory, or in bad faith. While a union has the right to decide not to take a weak case to arbitration, they must make that decision thoughtfully, investigate your claims properly, and communicate with you professionally.

Filing a complaint against your own union is a serious and highly complex legal step. The Ontario Labour Relations Board (OLRB) sets a very high bar for proving that a union breached its duty. Simply disagreeing with the union’s strategy is not enough to win. You must demonstrate severe negligence or malicious intent. Consulting with an independent employment law firm that understands unionized environments is crucial before filing your application.

Step-by-Step Process for Filing a DFR Complaint

Taking your union to the labour board requires meticulous documentation and strict adherence to OLRB procedures. Here is the standard path to holding your union accountable.

Step 1: Exhaust the Union’s Internal Appeal Process

Before you run to the OLRB, you must usually try to fix the problem internally. 🗣️ Many large unions have an internal appeal process outlined in their constitution. If the local steward refuses to file your grievance, send a formal written request to the union’s regional or national president. Keep every single email and letter; you will need to prove to the labour board that you gave the union a fair chance to correct its mistake.

Step 2: Understand the Three Legal Grounds

To win a DFR case, you must prove at least one of three things. Arbitrary: The union completely ignored your grievance, missed critical filing deadlines, or did no investigation. Discriminatory: The union refused to help you because of your race, gender, religion, or personal favouritism. Bad Faith: The union leaders lied to you, hid information, or acted out of personal hostility toward you.

Step 3: Drafting the Form A-29 Application

If the union still refuses to act, your lawyer will help you draft a Form A-29 (Application Concerning a Union’s Duty of Fair Representation). 🖊️ This is a highly detailed legal document where you must outline every fact, date, and conversation. You must explain exactly how the union’s behaviour meets the definition of arbitrary, discriminatory, or bad faith. Vague complaints will be instantly dismissed by the OLRB.

Step 4: Serving the Union and the Employer

Once your application is ready, you cannot just file it with the board. You must first deliver (serve) a copy of the complete application package to the union’s headquarters and to your employer. The employer is included because if you win the DFR complaint, the ultimate remedy is usually forcing the employer and the union to arbitrate your original grievance.

Step 5: Attending the OLRB Consultation or Hearing

After filing, the OLRB will usually schedule a Consultation or a formal Hearing. 👨‍⚖️ During a consultation, an OLRB Vice-Chair will review the documents and ask questions to determine if your case has any merit. If the Vice-Chair finds that the union clearly violated the OLRA, they can order the union to take your grievance to arbitration and order the union to pay for your independent legal counsel during that arbitration.

How Much Does it Cost in Ontario?

Fighting a large union and a corporate employer simultaneously can be a daunting financial prospect. 💰 While the board itself does not charge massive fees, legal representation is an investment.

  • OLRB Filing Fees: There is currently $0 (Free) filing fee to submit a Form A-29 Duty of Fair Representation complaint to the Ontario Labour Relations Board.
  • Initial Legal Consultation: Speaking with an experienced labour lawyer to review your collective agreement and union emails typically costs $300 to $600 CAD.
  • Drafting the Application: Having a law firm professionally draft the complex Form A-29 and manage the filing process generally ranges from $2,500 to $5,000 CAD.
  • Hearing Representation: If your case proceeds to a full OLRB hearing, legal fees can escalate to $10,000 to $25,000+ CAD, depending on how many days the hearing requires.

Valid vs. Invalid DFR Claims

Union ActionLikely OLRB Ruling
Missed a strict grievance deadline by forgetting to submit paperwork.Valid Claim (Arbitrary). Gross negligence that ruins your case is a breach of duty.
Investigated fully, consulted a lawyer, and decided your case was too weak to win.Invalid Claim. Unions are allowed to drop cases they honestly believe they will lose.
Refused to file a grievance because you campaigned against the local union president.Valid Claim (Bad Faith). Personal hostility and political retaliation violate the OLRA.
Negotiated a settlement for $10,000, but you wanted $20,000.Invalid Claim. Unions have the authority to settle grievances, even if you are unhappy with the final dollar amount.

How Long Does the Process Take?

You must act quickly! The OLRB expects you to file your DFR complaint almost immediately after you realize the union has abandoned you. If you wait more than a few months to file, the board may dismiss your case for unreasonable delay. Once the Form A-29 is filed, the OLRB typically schedules a Consultation within 60 to 90 days. If a full formal hearing is required, resolving the matter can take 6 to 12 months.

Frequently Asked Questions (FAQ)

Can I just sue my employer in regular court instead?

No. If you are part of a unionized bargaining unit, you have virtually zero right to sue your employer for wrongful dismissal in the Ontario Superior Court of Justice. Your only legal remedy is the grievance/arbitration process managed by your union.

Will the union pay my lost wages if I win the DFR?

Generally, no. The OLRB rarely orders the union to pay you damages directly for lost wages. The usual remedy is an order forcing the union to take your original grievance to an independent arbitrator, who can then order the employer to reinstate you with back pay.

Do I need a lawyer for the OLRB hearing?

You are allowed to represent yourself, but it is highly discouraged. You will be facing the union’s internal legal counsel and the employer’s corporate law firm at the same time. Having your own independent labour lawyer is crucial to surviving the complex OLRB procedures.

Can I file a DFR if the union refuses to take my case to arbitration?

Yes, but it is difficult to win. If the union processed your grievance through the early steps, reviewed the evidence, and made a reasoned, good-faith decision that an arbitration would fail, the OLRB will usually support the union’s right to allocate their financial resources elsewhere.

What if my union representative was just rude to me?

Being impolite or unprofessional is not necessarily a breach of the Duty of Fair Representation. The OLRB focuses on whether their actions genuinely prejudiced your employment rights. However, extreme hostility combined with a failure to represent you can form a bad faith claim.
