The Canadian government sources said the attack also disrupted email, Internet access and servers. Canadian cabinet minister Tony Clement who heads the Canadian Treasury Board, publically confirmed the attack on Twitter.

The Bill C-51 which is also called Anti-terrorism Act, 2015,  would broaden the mandate of the CSIS, giving the agency new powers to disrupt perceived security threats. The legislation, once enacted by the government, would also make it easier for federal agencies to increase surveillance and share information about individuals. The Anonymous who consider themselves the flagbearers of online freedom of speech and privacy have taken umbrage against the vast powers that the Canadian snooping agency, CSIS gets under this bill. They have asked online users to protest over the enactment of this law through a Pastebin paste. Anonymous had released a video in January, much before the law was being debated, warning Canadian citizens of the privacy and security issues with the C-51 https://youtu.be/krmCViA9oKY?t=51
