Francophones in Canada have achieved some gains. I am sure you have been told that today, there are French-language schools in Prince Edward Island and Nova Scotia because of the Court Challenges Program. Montfort Hospital survived because it received help under the Court Challenges Program. Good cases have been won by francophone minorities before the courts, not only because of the government's goodwill.
I would charge the Liberals with being just as responsible, since they were in power longer than the Conservatives have been.
