Another application has been submitted to the CRTC that protests an offer by Quebecor Inc.'s Videotron to not count data used by its mobile customers for certain music-streaming applications. Vaxination Informatique, a telecommunication consulting company, has launched its own undue-preference complaint about Videotron's offer, which was announced late last month. The application from Vaxination Informatique, which appeared on the CRTC's website on Friday, argued that Videotron's offer on music services, called Unlimited Music, contravenes Telecommunications Act provisions meant to "ensure fair treatment of all communications also to ensure incumbents do not use undue preference to a few services that act as poster boys that allow incumbents to claim low prices." The music services Videotron is exempting from regular data charges to its mobile customers are those offered by Stingray Digital Group Inc., Google Inc.’s Google Play, Deezer and Spotify AB. A similar complaint was already filed by the Public Interest Advocacy Centre (PIAC). Jean-Francois Mezei, who operates Vaxination Informatique, said in an email that he started the application before PIAC filed its complaint. He said the two applications are likely to be combined, a move that was requested of the CRTC by telecommunications researcher Ben Klass in writing on Tuesday.
