Hello, and welcome back.
Throughout this series, we’ve discussed foreign interference, democratic resilience, economic security, and the role each of us plays in protecting Canada’s open society.
Today, we’ll look at another important question.
Why do democracies need national security agencies?
At first glance, the answer may seem obvious.
But in a free and democratic society, it deserves careful consideration.
Many people associate national security agencies with secrecy.
Others wonder whether security and freedom are somehow in conflict.
In Canada, they are not.
In fact, one helps protect the other.
Freedom flourishes when democratic institutions are secure.
And security is strongest when it operates within the rule of law.
That is where the Canadian Security Intelligence Service—better known as CSIS—plays an important role.
Established in 1984, CSIS is Canada’s civilian intelligence agency.
Its primary responsibility is to identify, investigate, and assess activities that may threaten Canada’s national security, and to provide advice to the Government of Canada.
It is important to understand what CSIS does—and what it does not do.
CSIS is not a police service.
It does not arrest people.
It does not lay criminal charges.
Its role is to collect and assess intelligence—not to prosecute criminal offences.
Canada deliberately separates these responsibilities.
That separation reflects an important democratic principle:
Intelligence gathering and law enforcement serve different purposes and operate under different legal authorities.
The creation of CSIS followed the recommendations of the McDonald Commission, which concluded that intelligence activities should be separated from policing and placed within a clear legal framework.
That decision strengthened both national security and democratic accountability.
Just as importantly, the law also defines clear limits on CSIS’s authority.
The CSIS Act authorizes investigations into activities that may threaten Canada’s national security.
It does not authorize investigations based solely on a person’s ethnicity, religion, language, political opinion, or cultural background.
Lawful advocacy.
Peaceful protest.
Public debate.
Academic research.
Journalism.
Artistic expression.
Community participation.
These are all legitimate activities in a democratic society.
They are protected by the Canadian Charter of Rights and Freedoms.
Only when activities are connected to threats such as espionage, terrorism, foreign interference, sabotage, or violent extremism may CSIS investigate—and only within the authority granted by Canadian law.
National security agencies are themselves accountable.
CSIS operates under independent review and parliamentary oversight.
Certain investigative measures also require judicial authorization.
These safeguards help ensure that national security is protected while individual rights and freedoms remain fully respected.
In Canada, the rule of law applies to everyone—including national security institutions themselves.
That is one of the defining characteristics of a democratic society.
So remember:
National security agencies help protect democracy.
But democracy also protects how national security agencies exercise their powers.
Both are essential.
Both depend on the rule of law.
In our final episode, we’ll bring everything together with one final question.
How can we strengthen national security without creating fear or division?
Thank you for watching.
Together, let’s safeguard Canada.
