(GOC). The GOC, on behalf of the federal government, supports response coordination across the government and others. In practice, the immediate response to terrorist incidents in Canada is to be led by local law enforcement and emergency management authorities. This involves the RCMP as being the first police responder in those provinces and territories where it provides local police services. Particular terrorist incidents may involve specific responses from designated agencies; for instance, under the National Defence Act or through the Crown Prerogative, the Canadian Armed Forces can be called upon to respond directly to terrorist incidents in Canada.

Claiming that the safety and security of Canadians to be its first priority, the Government of Canada puts significant attention towards its counterterrorism efforts. "Building Resilience Against Terrorism" (2013) is Canada's first counterterrorism strategy, which aims to counter domestic and international terrorism so to protect Canada, Canadians, and Canadian interests. The strategy "assesses the nature and scale of the threat, and "sets out basic principles and elements that underpin the Government's counter-terrorism activities." The Canadian government uses the National Terrorism Threat Level (NTTL) to identify the probability of terrorism occurring in Canada. , Canada's current threat level is "Medium," which means that a "violent
