It is probably too late for you to file an application to the Human Rights Tribunal of Ontario.
The Human Rights Code says applications must be brought within 12 months from when the discrimination occurred.
If the discrimination is ongoing or occurred several times, the 12 months is counted from the most recent date. In rare circumstances the Tribunal will accept a late application. You must show that you wanted to file an application earlier but were unable to do so because of serious circumstances beyond your control, such as a major medical crisis.
