History and origin of CSIS

The Canadian Security Intelligence Service (CSIS) was established in 1984 as a result of the CSIS Act, which sought to establish a civilian intelligence agency in Canada independent of the Royal Canadian Mounted Police (RCMP). Previously, Canadian security intelligence was managed directly by the RCMP, but several investigations and controversies led to the creation of a civilian entity dedicated to protecting national security and managing threats on Canadian soil in a more specialized manner.

Since its inception, CSIS has expanded its focus to encompass a broad range of threats, including terrorism, espionage, cybersecurity and organized crime. Its mission is to protect Canada by gathering intelligence both at home and abroad. Over the years, CSIS has worked closely with other international intelligence services, establishing itself as a key ally in the defence of North American security.

Structure and functions of CSIS

CSIS is structured into several specialized divisions, allowing it to efficiently manage a variety of national security threats. As a civilian intelligence agency, it operates under the supervision of Public Safety Canada and collaborates with international intelligence agencies. The following are the most important functions of CSIS:

Homeland Security Intelligence

Homeland Security Intelligence focuses on surveillance and prevention of threats on Canadian soil. This division monitors and analyzes activities that may pose a risk to national security, such as terrorism, extremism and espionage . Its goal is to anticipate potential threats and respond preemptively, working in conjunction with other government agencies and local law enforcement.

Counterterrorism and Counterinsurgency

CSIS has a dedicated Counterterrorism Division responsible for identifying and neutralizing potential attacks in Canada. This division maintains a network of informants and uses advanced technologies to monitor suspicious activity that may be linked to international terrorism. It also works with intelligence agencies in North America and Europe to ensure Canada's protection from global threats.

Cybersecurity and Digital Threats Division

The CSIS Cybersecurity Division focuses on protecting critical infrastructure and monitoring potential cyberattacks. This division works to ensure the integrity of Canada's digital systems and prevent cyberattacks that could compromise the country's security. In recent years, this unit has gained greater relevance due to the increase in threats in cyberspace.
