I will agree with you. The minority status of the French language in North America and Canada is recognized in the Official Languages Act. The CRTC has responsibilities in this respect, and it acknowledges this, but it’s also found in paragraph 3(1)(c) and subsection 5(2) of the Broadcasting Act.
There are even specific points in the Broadcasting Act. Moreover, there was a CRTC consultation on the minority French language. These obligations also arise from those issues.
