OTTAWA — The people behind the hit Canadian TV show "Heated Rivalry" defended the Online Streaming Act — which the U.S. has identified as a trade irritant — at a Canadian media production industry conference in Ottawa on Thursday. "People have got to negotiate the way they've got to negotiate, but I think it would be really, really bad … if we lost it," said show creator Jacob Tierney. Large foreign streamers are currently challenging that contribution requirement in court. The annual industry conference is taking place as global streamers challenge Canadian content contribution and disclosure rules implemented by the CRTC through the Online Streaming Act. In December, a group of large foreign streaming companies also launched a separate challenge of a CRTC decision made under the legislation that would require them to disclose financial information.
