I know this sounds pedantic, but this is not necessarily the same as it being a full official language. If you look at the fine print there are ways where Manitoba falls short of New Brunswick, which is fully bilingual.

Here’s a radio-Canada article anout it: https://ici.radio-canada.ca/nouvelle/1541550/bilinguisme-francais-manitoba-nouveau-brunswick-droit-linguistique-constitution

(Granted it is from 2020. Maybe Manitoba had given French official constitutional status since then but if it has I was not aware of that change.)
