Canada has a new, more streamlined citizenship revocation process to safeguard Canadians’ safety from terrorism, effective immediately. 
The federal government can officially revoke citizenship from dual nationals who are convicted of terrorism, treason and high treason, and/or spying for foreign governments. 
Dual citizens who fought against Canada and the Canadian Armed Forces, whether as a member of a foreign army or in non-state terrorist groups like ISIS, can also have their Canadian citizenships revoked. 
In January 2015, the Anti-terrorism Act, was introduced so that law enforcement and national security, according to the federal government, can better protect Canadians from terrorism.
Included in this legislation is the extremely controversial Bill C-51 which will give Canada's spy agency CSIS a virtual 'free hand' to police the Internet and the judicial power to determine if someone's online comments, for example on Facebook, support a terrorist cause.
The bill has faced severe criticism from community leaders from all political backgrounds as it puts an unprecedented level of trust in Canadian police agencies to govern themselves.
