Thousands of Canadians joined in a protest across the country March 14 to denounce the Conservative government’s proposed anti-terror legislation, Bill C-51, which opponents say will allow to government to stifle protest and dissent.

Protest organizers say the bill would infringe upon Canadians’ civil liberties and right to privacy, especially online.
