^ The province of Quebec has 24 Senate divisions which are constitutionally mandated. In all other provinces, a Senate division is strictly an optional designation of the senator's own choosing, and has no real constitutional or legal standing. A senator who does not choose a special senate division is designated a senator for the province at large.
