The bill enjoyed support from a wide range of groups including municipalities, the Canadian Environmental Law Association, EcoJustice, Environmental Defence, Ontario Clean Air Alliance, Ontario Nature, Canadian Civil Liberties Association, Canadian Journalists for Free Expression, Citizens Environment Alliance of Southwestern Ontario, The Council of Canadians, CPAWS Wildlands League, Sierra Club Ontario, Registered Nurses' Association of Ontario and Greenpeace Canada. The Ontario Civil Liberties Association called upon the Attorney General to go even further, claiming Bill 83 did not correct fundamental flaws with Ontario's defamation law which impose a one-sided burden of proof to force defendants to disprove falsity, malice, and damage within a very limited framework where "truth", "privilege", "fair comment", and "responsible reporting" are their only recognised defences.
