Roughly 75 people gathered at Confederation Building on Saturday afternoon to display their displeasure with changes to the province's information laws.
The protest was organized by Occupy NL.
"We wanted to provide the opportunity for members of the public to express their outrage in the community," organizer Tom Baird said.
Politicians, students and musicians used signs, costumes and props to express how they feel about changes in Bill 29.
Protester Chris Bruce said "it really shocks me" that the auditor general can’t access certain information related to cabinet records, and the public will no longer be permitted to ask for policy briefing materials.
Bill 29 sparked a round-the-clock, four-day opposition filibuster in the legislature this past week.
The Tory majority in the house of assembly invoked closure, cutting off debate.
The bill passed in the early hours of Friday morning.
Critics say the legislation goes too far, and gives the government a broad array of powers to withhold information from the public.
Another protester, Ellen Adams, said she was worried about Bill 29’s impact.
"All the secrecy that’s going on with this government is what concerns me most," Adams said.
