Suing Your LTD Insurer vs. Filing a Grievance: Which Path Is Right for Your Claim?

The Threshold Question for Unionized LTD Claimants

When a unionized employee’s group LTD benefits are denied or terminated, they face a fundamental strategic choice: pursue the matter through a union grievance and binding labour arbitration, or bring a civil lawsuit against the LTD insurer in the Ontario Superior Court of Justice. The right answer depends on the terms of the collective agreement, the nature of the denial, and careful strategic assessment requiring experienced legal advice.

The Grievance and Labour Arbitration Route

Where the collective agreement incorporates group LTD benefits and requires grievance arbitration as the exclusive dispute resolution mechanism, the employee is typically required to use the grievance process. Union resources may be available — but the union represents its members collectively and may not always prioritize individual LTD disputes. The claimant should understand both what the union can do and the limits of its obligations.

The Civil Lawsuit Route

Where the collective agreement does not make LTD benefits a matter of collective bargaining, or where the insurer (rather than the employer) is the contracting party on the LTD policy, a direct civil lawsuit against the insurer may be available regardless of union membership. In some cases, both a grievance and civil action are theoretically available; in others, electing one forecloses the other. The interplay of collective agreement language, Insurance Act provisions, and limitations law makes this one of the more technically demanding issues in Ontario LTD litigation.
