Because that dropdown list is used to set other things but the language, such as date/time format, currency, default paper size... It has been considered important to provide a UI that clearly distinguishes between the display language and regional formats.
Even if the language is the same, I take for granted that "French (Canada)" differs from "French (France)" in several regional formats aspects. You know better than I do as regards "French (Belgium)", but Ubuntu assumes that the existence of a separate locale means that there is something that differs. Hence all the available locales are displayed on the regional formats list.
