Published Friday, May 14, 2021 6:26PM EDT OTTAWA - Heritage Minister Steven Guilbeault is doubling down on his controversial new broadcasting bill at a parliamentary committee hearing, citing a Justice Department analysis to reiterate the legislation would not affect free speech online. A charter impact statement from Justice officials this week found that the would-be law, known as Bill C-10, would not encroach on social-media users' freedom of expression. Opposition MPs remained unsatisfied Friday, however, demanding that Justice Minister David Lametti come before the House of Commons heritage committee to clarify points of contention around the bill. Work of the committee has been stalled since Liberal MPs on the panel moved to cut a section of the legislation that expressly excluded user-generated content from regulation.
