Last week, the Conservative party posted an offensive advertisement on YouTube and Facebook titled Justin Trudeau on ISIS. The ad starts with ISIS music and images of prisoners about be drowned or beheaded before running short edited clips from a 13 minute interview with Trudeau and the CBC's Terry Milewski. The advertisement has rightly generated a backlash with questions about whether it violates Bill C-51's prohibitions on terrorist propaganda. Conservative Party campaign spokesman Kory Teneycke argues that it is little different than newscasts involving ISIS, but watching the combination of music and imagery, it clearly goes well beyond conventional news reporting on ISIS. Indeed, even if it fall short of violating Bill C-51, the ad is in terrible taste, treating images of victims as mere props for political gain. Beyond the C-51 issue, the CBC waded into the issue late on Friday, as Jennifer McGuire, the CBC News Editor-in-Chief, posted a blog indicating that the broadcaster has asked YouTube and Facebook to take down the ad. The ostensible reason? Copyright. The CBC has again raised the issue of re-use of news coverage in political advertising, claiming that it is determined to limit re-use since "our integrity as providers of serious, independent coverage of political parties and governments rests on this." In light of this position, the CBC says its guiding principle is: No one - no individual candidate or political party, and no government, corporation or NGO - may re-use our creative and copyrighted property without our permission. This includes our brands, our talent and our content.
