CSIS investigates activities that fall within the definition of threats to the security of Canada, as outlined in the CSIS Act. Specifically, CSIS is authorized to investigate espionage and sabotage, foreign interference, terrorism and violent extremism, and subversion. Importantly, CSIS is prohibited from investigating lawful advocacy, protest or dissent, except when it is carried out in conjunction with activities that constitute a threat to the security of Canada.

Rising to the challenge: Confronting the contemporary threat environment 

As Deputy Director of Operations, Vanessa Lloyd is responsible for directing CSIS’ human intelligence collection, intelligence analysis, security screening and threat reduction efforts.

This year’s report highlights the persistence of threats that have been investigated by CSIS since our inception in 1984. In some cases, the threat has evolved in how it manifests itself, for example, espionage conducted by foreign intelligence agencies using proxies, or the use of criminal organizations by states to undertake transnational repression. Terrorism threats, which had abated in recent years as a result of purposeful multinational action, are re-emerging in the context of renewed conflict, for example, in the Middle East. New trends such as cyber threats to critical and government infrastructure, are increasing in frequency while others, like economic security, are becoming increasingly complex due to the speed of global innovation combined with increased threat actor focus.

In prior eras, CSIS rose to meet the challenge caused by surges of either espionage or terrorism and most recently, of foreign interference-related activities. In 2024, CSIS actively investigated espionage, foreign interference and terrorist threats, and for the first time in many years, also made concerted efforts to counter sabotage. Overall, threats to Canada’s national security have increased and are intensified. Most significantly, CSIS agrees with US and UK intelligence agency statements that never in our combined histories, have we faced threats of such magnitude simultaneously.

As we continue to improve as an organization, the ways in which we respond to protect Canada and its national interest also evolve. In 2024, we built new partnerships, deployed existing tradecraft in new ways and received new legislative authorities, specifically, new judicial authorities to help us address the realities of a digital and data-driven world that transcends geographic boundaries. Additionally, CSIS’ collaboration with international partners intensified through coordinated campaigns. We joined together to issue public warnings on intelligence threats, to denounce cyber actors and to inform citizens about concerning trends in youth radicalization.

In fact, 2024 saw unprecedented efforts at transparency with Canadians, including on our collaboration with law enforcement on individual cases, joint testimony with government partners before the House of Commons Standing Committee on National Security and the Public Inquiry into Foreign Interference (PIFI), and a public discourse on Canada’s response to acts of foreign interference that violated Canadian sovereignty and led to the expulsion of six Government of India officials one year after the Prime Minister’s statement on the matter in Parliament.

It was my privilege to speak to Canadians in the company of colleagues from the Canada Border Services Agency, the RCMP, Public Safety, and Immigration, Refugee and Citizenship Canada about CSIS’ role in immigration screening in the context of arrests in a terrorism case in summer 2024. Likewise, appearing at PIFI in September provided the opportunity to share with you CSIS’ long history of investigating foreign interference, our robust understanding of the threat and the extent of our commitment to address ongoing threat activity in advance of a general election in 2025.

It was also my privilege to serve as interim Director of CSIS, the first woman to fulfill this role, between mid-July and the end of October when we welcomed Dan Rogers to our ranks. My reflection on that assignment and on a year full of challenges and achievements at CSIS evokes enormous pride in its continued contributions to protect Canada and its national interests, as well as concern about the nature and scope of threats we are facing today.

CSIS employees, past and present, come from all backgrounds, and share a common passion: to keep our country secure and defend democracy from those who wish to destabilize it. They work tirelessly to gather intelligence to advise decision-makers, and they act decisively to keep Canada safe and prosperous.

It is my hope that this report will foster a continued conversation on how, together with all Canadians, we can improve our country’s national security.

Forty years of protecting national security: The evolution of the threat environment 

In 2024, CSIS celebrated 40 years of protecting national security as Canada’s security intelligence service. This major milestone provoked considerable reflection. How has the threat environment evolved since CSIS’ establishment in 1984? How has the threat environment changed, and what remains the same? How did CSIS respond to these threats over the last four decades? 

The world was a remarkably different place in 1984 when CSIS was created. The Cold War was still ongoing and conflict between the United States and its allies, and the Soviet bloc represented the greatest threat to international security. At that time, the key national security concern for the Government of Canada was espionage as it sought to stop Soviet bloc nations and other countries conducting espionage activities in Canada from gaining access to sensitive, privileged, and classified information on Canada’s military and government sectors. Canada’s counter-intelligence efforts throughout the Cold War decades resulted in the removal of around 100 individuals from the country for conducting activities deemed to threaten national security.

Although dangerous, the Cold War threat environment was predictable as it was centered on two main groups of adversarial states conducting espionage activities against one another to gain a strategic military or economic advantage. However, Canada was not immune to terrorism during the Cold War. In 1985, Canada-based extremists planted and detonated a bomb on Air India Flight 182, killing all 329 people onboard, the majority being Canadian. This tragic event remains the worst terrorist attack in Canadian history and, at the time, was considered the worst global terrorist event involving an aircraft. The failure to disrupt this event provided several hard lessons for CSIS to learn as a young security intelligence service.

The dissolution of the Soviet Union and end of the Cold War in 1991 shifted the threat environment significantly, as the predictably associated with great power conflict was replaced by increasing complexity and volatility. The collapse of the Soviet Union, and later Yugoslavia, created a power vacuum, which led to the emergence of several ethnic and nationalist conflicts within and between newly established nations. Increased violent activity across the globe by transnational terrorist organizations like Al Qaeda posed another significant concern. In response to the changing threat landscape, CSIS reallocated operational resources to meet the Government of Canada’s new priority of ensuring public safety. In 1993, CSIS redistributed resources from its Cold War era ratio of 80%/20% in favour of its counter-intelligence program to a more equal ratio of 56%/44% in favour of counter-terrorism. This would prove useful in light of increasingly violent attacks and plots by Al Qaeda, including the 1993 World Trade Centre bombing and the 1998 US Embassy bombings in Dar es Salaam and Nairobi. In 1999, a Canadian nexus to an Al Qaeda plot appeared as Canadian resident Ahmed Ressam planned to bomb Los Angeles International Airport around New Year’s Eve, 1999. Thankfully, this plot was foiled by a joint US-Canada investigation into Ressam that included CSIS.

Although public safety was CSIS’ primary focus during the 1990s, espionage remained a significant concern, as contrary to observer speculation, espionage activities directed towards Canada by foreign intelligence services did not significantly diminish with the dissolution of the Soviet bloc. In 1996, a CSIS investigation uncovered two Russian illegals living in Toronto under the assumed identities of deceased Canadians to develop their cover legends. The couple was deported from Canada after admitting they were intelligence officers for the Russian Foreign Intelligence Service. In 2020, CSIS acknowledged that it had observed espionage and foreign interference levels not seen since the Cold War.

The rise of information and communications technology in the late 1990s and onwards contributed greatly to the increasing complexity and volatility of the post-Cold War threat environment. The Internet provided terrorist organizations with greater means to organize, direct, and execute terrorist activities, while hostile state actors gained abilities to conduct ever more sophisticated threat activities, such as enhanced targeting of dissidents and critical infrastructure systems. CSIS and its partners understood the necessity of keeping pace with technological change at the time, as falling behind would have significant implications for Canada’s national security. This perspective remains true today as the threat environment evolves at an ever more rapid pace with the advent of new technologies like artificial intelligence and quantum computing. 

The world forever changed on September 11, 2001. Al Qaeda executed the single largest terrorist attack on US soil via coordinated aircraft hijackings, killing nearly 3,000 people, including 24 Canadians, and injuring countless others. The sheer magnitude of the September 2001 attacks changed the nature of the threat environment in North America, as it demonstrated the ability of terrorist networks to strike, with deadly force, anywhere within its shores. In response, the Government of Canada passed the Anti-Terrorism Act to strengthen Canada’s ability to combat terrorism by criminalizing the logistical and financial support of terrorist activity in Canada and abroad. Shortly after 9/11, CSIS redirected significant operational resources to address the heightened threat posed by terrorism and intensifying investigations into religiously motivated violent extremism (RMVE) in Canada.

As Canada’s military became involved in the US-led War on Terrorism effort in Afghanistan, so too did CSIS. Beginning in 2002, CSIS played a critical role in supporting Canada’s combat mission in Afghanistan by collecting information that would save the lives of many Canadian and coalition soldiers, and Afghan civilians.

In 2006, Canada experienced its first instance of ‘homegrown’ terrorism in the 9/11 era. The public story about the Toronto 18 case began in 2006 with the arrest of a large group of extremists from the Toronto area on suspicion of planning a mass-casualty attack with explosives targeting the Toronto Stock Exchange, CSIS’ Toronto office and an unidentified military base. CSIS had been tracking this plot before 2006 as it had been monitoring the suspects closely by using a variety of cutting-edge investigative tools along with more traditional methods such as human sources and physical surveillance. CSIS’ investigation, along with the separate, parallel investigation by the RCMP, successfully thwarted the terrorist plot and resulted in the imprisonment of 11 of the original 18.

The elimination of Osama Bin Laden, the architect of the September 2001 attacks, in 2011 symbolized the end of the 9/11 era. However, the rise of Daesh (also known as the Islamic State, ISIS or ISIL) in the 2010s indicated that the RMVE threat would not diminish after Bin Laden’s demise. Daesh announced the formation of a so-called caliphate in 2014 after gaining control of significant swaths of territory in Syria and Iraq. Daesh became notorious for committing grotesque acts of violence, including by beheading journalists; conducting a series of prolific terrorist attacks abroad, and attracting thousands of foreign fighters from around the globe. Although Daesh has since lost all of its territories comprising its Middle East caliphate, the group, along with Al Qaeda, still poses a significant threat via its network of provinces, affiliates, related loose online networks, and due to its ability to inspire Canada-based threat actors to commit serious acts of violence, as experienced in Canada in recent years.

The occurrence of ideologically motivated violent extremism (IMVE) activity during the 2010s both globally and domestically led CSIS to establish a greater investigative focus on IMVE. Since 2014, Canada has experienced several IMVE-related attacks, with the most notable being the 2017 Québec City mosque shooting that tragically resulted in the loss of six lives and injury of 19 others by a lone actor. By 2023, IMVE represented approximately 50% of all CSIS counter-terrorism investigations. Lone actor attacks, such as the Québec City attack, characterize the complexity of the contemporary threat environment, as even individuals can have significant impacts on public safety.

In recent years, technology has shifted the threat landscape even further. It is not the same environment CSIS knew in 1984 when it was created. The interconnection of information technology systems and digitization of society has both systematically reshaped human life and consequently revolutionized the threat environment. Now, hostile actors can conduct sophisticated threat activities around the globe at tremendous scales without ever having to step outside their own borders. In terms of espionage, the digitization of information and ubiquity of connected devices has significantly expanded the scope of information vulnerable to collection, while advances in data storage and analytics allow for the stockpiling, analysis, and exploitation of collected data at a scale inconceivable 40 years ago.

During the Cold War period, foreign intelligence services primarily focused targeting efforts on individuals with access to sensitive or classified information, such as Government of Canada employees or researchers working on controlled technologies. Now, foreign intelligence services also target organizations across all sectors and ordinary Canadians through direct or indirect means. Targets include, but are not limited to, tech start-ups and legacy manufacturers; individuals associated with governments at all levels, including federal, provincial, territorial, municipal and Indigenous; students who have had their digital information stolen in a cyber event targeting a university; and patients who lose vital access to healthcare via ransomware targeting a hospital.

While technological advancements have changed how threats to national security can manifest, in general, the key underlying threats facing Canada today remain the same as in decades past. For instance, much like the Cold War period, foreign interference and espionage remain a significant concern. Revelations from testimonies to PIFI concerning the sophistication and level of foreign state interference in our democratic institutions and electoral processes indicate that adversarial states are targeting Canada with far more interest than ever before. Attempts by hostile states to acquire Canadian proprietary information throughout the last four decades signify that economic espionage has remained a key national security threat since CSIS’ inception in 1984. The same can be said for violent extremism. Threats posed by violent extremism has ebbed and flowed over the last four decades due to key global events and technological change, however, violent extremists who are driven by a variety of grievances continue to threaten public safety in Canada and around the world with serious acts of violence.

The world has changed considerably in the last 40 years. So has Canada. Major shifts around the world have impacted the threat environment, and while certain threats remain, the rise and dominance of technology and the online ecosystem has given rise to new and rapidly evolving challenges. As a modern intelligence service, CSIS will continue to pivot to address threats posed by hostile actors who seek to undermine the security of Canada and all Canadians.

Foreign interference and espionage

Foreign interference and espionage activities in Canada continue to be pervasive, sophisticated, and persistent. Active targets of these activities include institutions at all levels of government, private sector companies and associations, universities, civil society groups, and ethnic, religious and cultural communities within Canada. Despite increased public awareness in foreign interference and espionage activities in Canada, foreign states remain committed to advancing their interests in ways that are injurious to Canada’s national security and social cohesion.


"Many foreign intelligence services attempt to influence, interfere with or intimidate Canadian ethnic communities. Their purposes vary, but include attempts to ensure that opposition to their governments’ policies does not develop in Canada, to recruit agents to operate in Canada and to endeavour covertly to influence Canadian government policy." - CSIS Public Report 1993






Islamic Republic of Iran

In 2024, Iran continued to advance its policy of cementing itself as a regional power and, for the first time in its history, engaged in a direct exchange of fire with Israel. Despite electing a new, more moderate president, Iran continued to support its allies and proxies across the Middle East in Iraq, Syria, Lebanon and Yemen to counter both Israel’s military operations in Gaza and Lebanon and, more broadly, the United States and Western interests. The “Axis of Resistance,” an Iranian-led regional alliance with Syria, Lebanese Hezbollah, and Iran-aligned non-state armed actors in Iraq and Yemen, conducted multiple military attacks against Israel. In two separate attacks, on April 13 and October 1, 2024, Iran launched more than 500 ballistic missiles, uncrewed aerial vehicles, and cruise missiles against Israel. Despite its efforts to project strength, Iran has suffered numerous losses in 2024, as the capabilities of its regional partners, notably Hamas and Lebanese Hezbollah, have been significantly degraded. The deaths of Hamas leader Ismail Haniyeh and Lebanese Hezbollah leader Hassan Nasrallah, is a significant blow to Iranian interests.

In June 2024, the Government of Canada designated Iran’s Islamic Revolutionary Guard Corps (IRGC) as a terrorist entity under the Criminal Code, adding to its previous designation of the IRGC Qods Force (IRGC-QF) in 2012. Between October 2022 and September 2024, Canada has imposed sanctions under the Special Economic Measures (Iran) Regulations against 205 Iranian individuals and 250 Iranian entities linked to systematic and gross violations of human rights in the country.

In 2024, Canadian citizens Damion Ryan and Adam Pearson were indicted by the US Department of Justice for their role in an alleged murder-for-hire plot targeting two residents of Maryland who had previously defected from Iran. The Canadian men were allegedly directed by Iranian-Turkish narcotics trafficker, Naji Sharifi Zindashti, who led a network of individuals that targeted Iranian dissidents and opposition activists for assassination at the behest of Iran’s Ministry of Intelligence and Security. This network has carried out numerous acts of transnational repression including assassinations and kidnappings across multiple jurisdictions in an attempt to silence Iran’s perceived critics.

CSIS continues to investigate threats to life emanating from the Islamic Republic of Iran based on credible intelligence. CSIS assesses that Iran will continue to use proxies, such as individuals involved with transnational organized crime networks, when it targets perceived enemies living in foreign countries, including Canada. Iranian threat-related activities directed at Canada and its allies are likely to continue in 2025, and may increase depending on developments in the Middle East and the Iranian regime’s own threat perceptions.  



"While not as hostile as they once were, Russia’s and the People’s Republic of China’s intelligence services nevertheless remain active against Western interests. Currently, CSIS has identified several countries with known or suspected, undeclared intelligence officers operating in Canada. They conduct activities ranging from monitoring their own citizens to penetrating and coercing Canadian ethnic communities and/or collecting military, economic and technical intelligence." - CSIS Public Report 1992

Violent extremism

Violent extremism, whether it is religiously, ideologically, or politically motivated, continues to pose a significant threat to Canada’s national security. The overall violent extremist threat to Canada has remained at a heightened level, as online radicalization has contributed to an increased number of extremists mobilizing to violence, some of whom are youth. Monitoring, investigating, and mitigating these serious threats are a key priority for CSIS and its national security partners. 







"Terrorism in the years ahead is expected to become more violent, indiscriminate, and unpredictable than in recent years[…] There will likely be terrorist attacks whose sole aim would be to incite terror itself. A hardening attitude and willingness on the part of certain terrorist organizations to directly support terrorist operations in North America reinforce the belief that Canadians, now more than ever, are potential victims and Canada a potential venue for terrorist attacks." - CSIS Public Report 2000

Cyber security 

Canada’s strong democratic institutions, advanced economy, innovative research sectors, and leading academic institutions make Canada an attractive target for cyber-enabled espionage, sabotage, and foreign influenced activities, all of which pose significant threats to Canada’s national security. Cyber-enabled foreign interference activities targeting Canada will continue to increase in breadth and sophistication. 




"A principal factor currently underlying all security issues is the impact of technological change. The reliance of modern countries on the unimpeded and secure flow of information electronically has created vulnerabilities within their information infrastructure that are serious enough to raise international security concerns. The already complex investigation of threats posed by terrorism and intelligence activity is further complicated by the adoption of cyber technology by foreign intelligence organizations and terrorist groups." - CSIS Public Report 2000

Economic and research security

As a trading nation and global leader in the research and technology sector, Canada is a prime target for hostile state actors, including the PRC, Russia, and Iran, who seek to acquire sensitive research and technology to advance their own strategic political, economic, and military interests. Threats to economic and research security are increasingly complex and multifaceted in nature as hostile states continue to take advantage of weaknesses in Canada’s legal and regulatory frameworks to undermine Canadian interests.




Secure your environment/products/partnerships [Infographic]

Secure your environment

Your assets include people, premises, products and services, as well as your information, intellectual property (IP) and knowledge. Identifying the value of each of these assets-and any necessary security measures-is an ideal starting point, since protection of these assets will determine the ultimate success of your company.

Understanding the following will help you to determine which risks to prioritize:

  • Your company's goals and priorities.
  • Your most critical assets.
  • The threats to those critical assets.
  • The likelihood and consequences of a threat affecting you.

Although it may not be possible to protect against every threat, security protections will pay long-term dividends, particularly when possible threats are assessed and mitigated alongside any other risks.

Security measures should be based on a combination of information, physical, human and cyber security measures.

Secure your products

When designing products, security issues, including the assurance that products are free from any security vulnerabilities, should be addressed as soon as possible.

Understanding the value and purpose of your assets will help you devise effective intellectual asset (IA) and IP management strategies. You need to understand:

  • What needs to be protected.
  • How it can be protected.
  • What in-country laws are in effect for countries in which you operate.
  • How to manage your IP.

Secure your partnerships

Partnerships, including with investors, suppliers or other researchers, increase the vulnerability of your company-and any information or data you may share. As you expand, you may need to manage additional risks associated with increased collaboration. Your choice of partners may affect future business partners. Answering the following questions will help you manage the additional risks that collaboration brings.

Why you are collaborating?

  • Think about the outcomes you need; the benefits a partner can bring: the risks and red lines.

With whom are you working?

  • Conduct due diligence on all prospective partners.

What are you sharing?

  • Be strategic about what and when you share with partners.

How are you protecting your innovation?

  • Include protections for your assets and data contracts.


"Studies conducted by CSIS in 1990-91 led to the observation that a small group of leading-edge companies in Canada had been targeted by foreign intelligence services between 1980 and 1990. In fact, in a more recent case of economic espionage, which involved support from a foreign government, a Canadian company lost a major contract after precise information contained in the company’s tender was passed to an offshore competitor." - CSIS Public Report 1993

Counter proliferation

CSIS’ counter-proliferation efforts substantially reduce the risk of Canadian technology and research being utilized to advance the military capabilities of adversarial foreign states. In response to CSIS’ efforts, adversarial states are applying increasingly complex strategies to mask their illegal procurement activities.


"As Canada is an internationally recognized leader in many high-technology sectors (such as nuclear, chemical, electronics and aerospace sectors), it has been, and will remain, a lucrative target for clandestine and illicit procurement activity." - CSIS Public Report 1994
