I would briefly like to add that the message sent to anglophone and francophone minority communities is simple: cancelling the Court Challenges Program means that it's not worth continuing to try to live in the minority language. That is the message being sent.
You are wondering what the impact will be. The impact will be increased assimilation in Canada. That is a direct impact starting now. In fact, the government is sending all those small communities where people are fighting to preserve their own language the message that it's not worth doing it anymore.
