C51, also known as the Anti-Terrorism Act, 2015, is a Canadian law that was enacted to enhance national security. It aims to provide law enforcement agencies with additional tools to prevent and respond to terrorist activities. The legislation includes provisions for information sharing among government agencies and allows for the monitoring of individuals suspected of planning terrorist acts. The law has been controversial, with critics arguing that it infringes on civil liberties and privacy rights. Supporters, however, believe it is necessary for protecting citizens from potential threats. The debate surrounding C51 highlights the ongoing challenge of balancing security and individual freedoms in a democratic society.
