As Ezra suggests, this could be another Erin Brockovich story. Moreover, Nextera is likely going to learn the lessons of the Streisand effect, which is that trying to suppress a discussion on the internet usually just draws more attention to it.
If NextEra pursues this matter, it will no doubt be reminded that "parody" is now explicitly included in s. 29 of the Copyright Act as one of the recognized purposes of fair dealing. In the light of that amendment and recent Supreme Court of Canada decisions having to do with fair dealing, the 1997 Michelin decision is surely no longer good law - if it ever was - with respect to copyright. That was the case in which Michelin used copyright law to stop a union from protesting with a parody of "Bibendum", the jolly Michelin character and design trade-mark And even that decision correctly held that the defendant did not "use" Michelin's trade-mark within the meaning of "use" under the Trade-marks Act. The reasoning with respect to trade-mark "use" is still good law. And recent Supreme Court of Canada defamation decisions suggest that claims that attempt to accomplish via the Trade-marks Act what cannot be accomplished via normal defamation law may face a very rough ride if adequately challenged.
