How to change a complaint
A complainant must:
- File a Form 3 – Amendment
- Deliver a copy to the other participants
- Apply to change the complaint if required
There are two kinds of changes to a complaint:
- Adding details about conduct in the complaint. The legal term is “particulars”.
- Adding new conduct that the complainant says is discrimination. This is called a “new allegation”.
You don’t need to apply if you want to add details about conduct in the complaint.
When a complainant must apply to change a complaint
Rule 24 of the Tribunal’s Rules of Practice and Procedure apply to amending a complaint.
You must apply to add a new allegation in three situations.
- The hearing is less than 4 months away
- The respondent applied to dismiss the complaint and the Tribunal has not decided the application
- The new allegation occurred outside the time limit for filing the complaint under s. 22 of the Human Rights Code
Legal test: change a complaint if the hearing is less than 4 months away
- Participants need enough time to prepare for the hearing. You can add a new allegation if the hearing is more than 4 months away.
- If not, you must show that changing the complaint will help get to a “just and timely resolution” of the complaint.
- The Tribunal will consider the effect on the process and the outcome.
- How will it affect the time to solve the complaint?
- How much would it cost the other side?
- Would it affect a participant’s ability to present their side?
- Would it affect a participant’s chance to have a say about something important? For example, something that could affect the outcome of the complaint.
- In the application, explain:
- How is the change important?
- Why didn’t you change the complaint earlier?
- Will the change delay the hearing?
Legal test: the respondent applied to dismiss the complaint
- A respondent may apply to dismiss the complaint. It might be unfair to change the complaint after this happens.

Legal test: change to complaint is late
If the change to the complaint is late, you must show two things.
- There is a good reason to accept the new allegation. The legal term is that it must be in the “public interest”.
Reasons include:- why you are adding the allegation late
- why adding the new allegation would benefit the public
- The delay does not cause real harm to anyone. The legal term is no “substantial prejudice”.
- The delay means the time after the 1-year time limit.
- Real harm includes things like the respondent no longer has evidence they need to respond to the complaint.
- Set out any harm. Explain how the Respondent can still defend against the allegation.
- Or say, “I know of no harm to the Respondent.”
