About Standing

In Ontario employment law, "standing" (or locus standi) refers to a person's legal right to initiate a lawsuit, file a complaint, or participate in a legal proceeding. Having a legitimate grievance does not automatically grant you courtroom access; you must prove to the court or tribunal that you have a sufficient legal connection to the issue and have suffered a direct harm.

Standing is a critical threshold question, particularly when the lines of legal representation are complex. One of the most common areas where standing issues arise is in unionized workplaces. Under Ontario’s Labour Relations Act, 1995, a certified trade union has the exclusive right to represent its members. Consequently, an individual unionized worker generally lacks the standing to sue their employer directly in civil court for matters like wrongful dismissal, or to personally seek a judicial review of an arbitration decision if the union chooses not to proceed.

Standing is also heavily scrutinized in human rights allegations under the Ontario Human Rights Code. While an employee clearly has the right to file an application regarding discrimination they personally endured, courts and the Human Rights Tribunal of Ontario (HRTO) will often strike out claims where an individual attempts to seek remedies on behalf of unidentified, anonymous coworkers who allegedly faced systemic discrimination. Unless the case is certified as a formal class action under the Class Proceedings Act, an individual worker's standing is usually limited to their own personal losses.

The issue can also affect third parties. For instance, if an HRTO decision severely damages the reputation of a manager who was not an official party to the hearing, that manager might attempt to establish standing to seek a judicial review based on procedural unfairness.

Figuring out exactly who possesses the legal authority to pursue an action can be technically arduous. Proceeding without the proper legal footing can result in a claim being struck down entirely, often with negative cost consequences. Accessing tailored counsel from a qualified Ontario employment practitioner is a crucial step to confirm you possess the necessary standing before launching a claim.

Frequently Asked Questions

What does 'standing' mean in a workplace legal dispute?

Standing refers to your legal right to bring a claim or participate in a legal proceeding. To have standing, you must demonstrate to a court or tribunal that the law or action in question directly affects your personal legal rights or causes you specific harm.

Do I have standing to sue my employer if I am part of a union?

Generally, no. Under the Ontario Labour Relations Act, your union has exclusive bargaining rights. This means the union has the standing to address employment disputes through the grievance and arbitration process, barring individual employees from initiating civil lawsuits for issues covered by the collective agreement.

Can I file a human rights complaint for discrimination happening to my coworkers?

Unless you are bringing a formalized class action, you generally lack standing to claim remedies on behalf of other employees. Under the Ontario Human Rights Code, you must rely on the discrimination or harassment that personally impacted you.

What happens if a judge decides I do not have standing?

If a court or tribunal rules that you lack standing, they will dismiss your claim or strike out the portions where you overstepped your legal footing. You may also be ordered to pay a portion of the other party's legal costs.

Can a third party get standing to challenge a Human Rights Tribunal decision?

It is difficult but possible. If an individual, such as an accused manager, was not a party to the original hearing but suffered significant reputational or financial harm from the ruling, they may petition the court for standing to seek judicial review on the grounds of procedural unfairness.

At what point should an employment lawyer review my standing to sue?

You should have a legal professional assess your standing before you ever file or serve a statement of claim. Initiating an action without the proper legal right to do so can stall your case immediately and result in costly motions.

Common Scenarios

  • A unionized factory worker's grievance is dismissed at arbitration, and after the union refuses to appeal the decision, the worker tries to file their own judicial review application, only to have the employer challenge their standing.
  • A retail employee files a lawsuit claiming racial discrimination and attempts to secure financial damages on behalf of five other racialized employees who have not come forward or authorized the claim.
  • A director is unexpectedly referenced in a workplace harassment tribunal decision between an employee and the corporation; to clear their name from public record, the director fights for standing to challenge the findings.
  • A non-unionized worker brings a massive civil claim regarding systemic underpayment of wages across their entire sector, prompting the employer to file a motion to strike out the systemic claims because the worker lacks standing as a representative plaintiff.

What You Should Know

  • Keep your civil claims strictly focused on your own personal damages and the specific legal breaches you directly experienced, rather than attempting to advocate for unidentified peers.
  • If you belong to a union, always route your workplace disputes through your union representative, as the collective agreement strips away your individual standing to sue in civil court.
  • Employers facing a claim from an individual who suffered no direct harm can efficiently defend themselves by bringing an early motion to strike the pleading for lack of standing.
  • Because establishing standing is the mandatory gateway to the justice system, consulting with an Ontario employment lawyer to evaluate your legal position should be your first strategic step before asserting any formal legal action.
