In 1643 Fr Jean de Brébeuf, Jesuit missionary to the Huron, wrote the first Canadian Christmas carol. In Huron it's Jesous Ahatonhia; the English version is called the Huron Carol or 'Twas in the moon of wintertime'.
First Nation Help Desk has a Huron carol page which features an .mp3 of the song being sung in the Huron language. Excellent! I've wanted to hear that for years.
Here's the story of Jean de Brébeuf, his mission to Huronia, and his martrydom.
