Dozens of people rallied in Barrie on Saturday morning to protest against the government’s proposed anti-terrorism law.

Protestors rallied outside of Patrick Brown’s office, voicing their displeasure over Bill C-51. The wide-ranging bill would give police much broader powers and allow them to detain terror suspects and give new powers to Canada's spy agency.

The Barrie demonstration is part of a Canada-wide event dubbed “Defend our Freedom.” Several other rallies took place in communities from Victoria to Halifax.

Organizers call the government's bill dangerous, reckless and unacceptable.Critics say the bill, if enacted as law, will infringe upon Canadians' civil liberties and right to privacy, especially online.

The Conservative government introduced Bill C-51, in January. The Tories say it will make Canadians safer.
