Hoi,
For languages with an ISO-639-3 code it is OK to have Wikidata support them. For French and in particular Canadian French the same rationale does not exist.

What is our opinion about including Canadian French as a Wikidata only language? In my opinion it is only through the same way as it is done for British English that this is fine.
Thanks,
