On 24 October, the Ontario Superior Court held that the definition of “terrorist activity” in the 2001 Anti-Terrorism Act (ATA) violated freedoms of religion, expression and association guaranteed under the Canadian Charter of Rights and Freedoms. The Court struck down the part of the definition that required a political, religious, or ideological objective or cause. On 19 October, the same court held that some provisions of the Security of Information Act (SIA), amended in the aftermath of the 9/11 attacks, violated freedom of expression and the media by allowing the Government to arbitrarily classify information and to punish those who communicate or confirm such information.
