Statistics Canada has a number of advisory boards. One of them is on language statistics. You're appointed to the board by the chief statistician for a period of time. You're appointed as an individual. The board meets a couple of times a year.
It's not specific to official languages; it's about language statistics in general. I would encourage the committee to ask Statistics Canada. I think they are coming later this month, and I would encourage you to ask Statistics Canada about the committee.
