The outgoing Chief Commissioner of the Canadian Human Rights Commission, Mary Gusella, made it an enormous priority during her tenure to try to reduce the serious backlog. My understanding is she made enormous strides, putting particular emphasis on the use of mediation.
Given the arm's-length relationship between the commission and the minister, it might be appropriate to invite Ms. Gusella or her successor to give the statistics on her behalf. But I think it's a good story that they would be able to tell.
