There are eight aboriginal languages plus French and English, and of course in Nunavut there are four languages.
The precedent of a legislature using an aboriginal language in Canada exists in the Northwest Territories and in Nunavut. In fact, there was a fact-finding mission of senators who went to Nunavut in 2008 to look into how it works and how it is integrated into the daily practice, because in Nunavut, 89% of the debate takes place in Inuktitut.
