I can't remember a request for it. The NAAD system has supported four indigenous languages since it was built in 2010, those being Cree, Dene, Inuinnaqtun and Inuktitut. I believe the Inuktitut feature has been used for some of the test alerts in Nunavut, but the others have not been used in a live alert.
On October 3rd, 2022. See this statement in context.
