The B.C. Human Rights Code allows a complaint to be filed on behalf of another. See s. 21:
a complaint under subsection (1) may be filed on behalf of (a) another person, or (b) a group or class of persons whether or not the person filing the complaint is a member of that group or class.
The Tribunal may order the contravening party to:
- stop the discriminatory practice,
- take steps to ameliorate the effects of the discriminatory practice,
- make available to the person discriminated against the opportunity that was denied,
- compensate the person discriminated against.

Ontario has a similar provision. See s. 34(5). It empowers a third party to seek an order directing compensation or restitution to the party whose rights were infringed or an order directing the infringer to do anything that would promote compliance with the act.
Ontario also has a Human Rights Commission with the power to independently bring a matter to the Human Rights Tribunal.
The above probably cannot be used to bring a claim on behalf of a deceased person. See HMTQ v. Gregoire, 2005 BCSC 154, at para 32:
human rights established by the Code are “personal” and abate on the death of the person whose human rights have been breached.
However, that limitation would not prevent the Ontario Human Rights Commission for bringing a systemic issue to the Tribunal, seeking one of the non-compensatory remedies.
