Answer :
French is a very popular language in which it expanded in many ways but mostly through settlements in new areas. Back in the late 1700's and early 1800's people from France were coming to now a day Canada because a lot of them liked it here. That is one way of it expanding, by new settlements. The other way- and not so popular- was because it could also have been the root to a new language. French is a lot like Spanish and English in a way so there is other ways that it could be like that too.
