The Globe and Mail reports in its Friday edition that dozens of leading Canadian film and television organizations -- including the Canadian Media Producers Association, the Directors Guild of Canada and Hot Docs -- issued an open letter Thursday to the federal government underlining the "significant uncertainty" that Ottawa has introduced into the multibillion-dollar industry over the state of the Online Streaming Act. The Globe's guest columnist Barry Hertz writes that in June, the Department of Canadian Heritage ordered the Canadian Radio-television and Telecommunications Commission to review its May policy regarding the Online Streaming Act, which would have tripled the contributions of such foreign-owned streamers as Netflix and Amazon toward the production and promotion of homegrown content, including local news, to 15 per cent from 5 per cent of their Canadian revenues. At the time of its policy U-turn in June, Canadian Heritage said that the costs imposed by C-11 "could ultimately fall on Canadian consumers through higher prices," sentiments echoed by Prime Minister Mark Carney in remarks to reporters last month. Amazon, Apple and Spotify have taken action in Canadian federal court in a bid to stop the law.
