Youth Radicalization Rising in Canada as CSIS Report Warns of Growing Online Terrorism Risks
A new report from the Canadian Security Intelligence Service (CSIS) has raised serious concerns about the increasing involvement of young people in terrorism-related investigations across Canada. The findings suggest that youth radicalization in Canada is becoming a more visible and troubling national security issue, with some individuals under investigation reportedly as young as 13.
According to the CSIS year-end report for 2025, nearly one in 10 counter-terrorism investigations now involves at least one person under the age of 18. This has sparked renewed concern among security experts, cybersecurity analysts, parents, and policymakers about how extremist content is reaching young people through digital platforms.
CSIS Report Highlights Alarming Youth Radicalization Trend
The CSIS report states that counter-terrorism investigations are increasingly encountering minors who may be moving toward violence. This does not mean every young person exposed to extremist content becomes a security threat, but it does show that radicalization among youth is no longer a distant concern.
The agency noted that minors are regularly appearing in investigations linked to terrorism-related activity. This has placed a spotlight on how vulnerable young people are being influenced by online extremist material, violent propaganda, and direct communication with radical networks.
The report points to both ideologically motivated violent extremism and religiously motivated violent extremism as key factors behind the trend.
Online Extremist Content Targeting Vulnerable Youth
Former CSIS intelligence officer Neil Bisson described the trend as concerning, though not entirely surprising. He said the internet, social media, and digital communication have created new opportunities for extremist actors to reach impressionable young people.
Many teenagers spend hours online each day, often in digital spaces where parents, schools, and authorities may have limited visibility. These spaces can include social media apps, private chat groups, encrypted messaging services, online forums, and gaming platforms.
Experts warn that extremist groups can use these platforms to spread propaganda, build trust with young users, and gradually push them toward dangerous ideas. In some cases, the process can begin with memes, videos, political anger, religious messaging, or conspiracy-style content before moving into more extreme material.
Why Youth Radicalization Is Difficult to Detect
One of the biggest challenges identified in the CSIS report is determining which young person consuming violent or extremist content online may actually become a real-world threat.
Many teenagers may view disturbing material out of curiosity, peer pressure, anger, or emotional confusion. However, only a smaller number may move toward actual violence. Security agencies must therefore separate online behaviour that is concerning from behaviour that signals a genuine risk of mobilization.
This makes youth radicalization especially difficult to investigate. Authorities must consider age, intent, mental state, online contacts, access to weapons, ideology, and signs of planning before deciding whether a person poses an immediate threat.
Social Media, Gaming, and Encrypted Platforms Under Scrutiny
Cybersecurity and technology analyst Ritesh Kotak said young people can be reached through several digital channels, including social media, encrypted messaging apps, and online gaming platforms. These platforms can allow strangers to communicate directly with minors, sometimes with little oversight.
Online gaming communities, in particular, may seem harmless at first but can include private chats, voice communication, and closed groups where harmful content can spread. Encrypted messaging apps also make monitoring extremist communication more difficult for authorities.
Kotak suggested that stronger regulation could push online companies to take greater responsibility for harmful content. He also argued that platforms should do more to protect youth and ensure their digital environments are safer.
Arrests of Minors in Counter-Terrorism Cases
The CSIS report included figures showing that minors have already been arrested in connection with counter-terrorism investigations in recent years. According to the report, five minors were arrested in 2023, two in 2024, and four in 2025.
These numbers highlight how youth involvement in extremist activity is not only theoretical. It has already led to criminal investigations and arrests.
In a recent Ottawa courtroom case, a young person was found guilty of terrorism charges connected to Islamic State-inspired plans to attack Jewish people. The case has further intensified concern about how extremist ideology can influence minors and develop into real-world threats.
Growing Pressure on Online Platforms
The rise in youth radicalization in Canada is increasing pressure on technology companies to improve safety systems. Experts say platforms need stronger content moderation, faster removal of extremist material, improved reporting tools, and better protection for underage users.
Parents and educators are also being urged to pay closer attention to sudden behavioural changes, extreme political or religious language, isolation, secretive online activity, or growing obsession with violent content.
However, experts warn that prevention should not rely only on surveillance. Support, education, digital literacy, and early intervention are also important. Young people who feel isolated, angry, rejected, or confused may be more vulnerable to radical messages online.
