I know that the stats nerds like to wax poetic about median vs. average any chance they get, but it helps to consider what you're replying to before jumping in. (Not calling you a stats nerd, per se, just that it seems likely
someone's going to jump in any time average is mentioned).
You even said so yourself, that a "regional average is more relevant", so it seems that you would even agree; in the context of that statistic, average would be a fine metric... Since it was referring to the Toronto District School Board, which sounds pretty regional to me.
And even though there wasn't any other context in the article, it seems pretty safe to infer that if the TDSB measures class sizes against the ON provincial benchmark, then most likely the benchmark is measured per school division or school board, which would likely address the issue of averaging Calgary and Crossfield in the example you made... CBE would be one average, CSSD would be another and whatever-the-#### school board runs Crossfield would be another, etc etc, all measured against whatever benchmark the province set... But now we're veering into fantasy land, because we know the UCP would never set a class size benchmark hahaha
