Report a Threat to National Security
Fraudulent emails and phone calls - Protect yourself!
CSIS contacts people via telephone for legitimate purposes as part of our mandate. The warning below should not be interpreted to apply to such contact from representatives of CSIS.
If you receive a phone call or an on-line pop-up message asking to either give access to your computer, or pay a certain amount of money to unlock your computer or your phone from someone claiming to be from the Royal Canadian Mounted Police, Canadian Security Intelligence Service or Canadian Cyber Incident Response Centre, please be aware that it is a scam.
Never give remote access to your computer in response to an unsolicited call or message.
We strongly encourage Canadians to report such instances of fraud to the Canadian Anti-Fraud Centre by phone 1-888-495-8501 or via their website at http://www.antifraudcentre-centreantifraude.ca/
Are you aware of something that may pose a threat to national security, such as terrorism or espionage? If you believe CSIS should know about your information, please report it.
CSIS is not a law enforcement agency. To report an immediate threat to national security, please call 911 or your local police department. You can also contact The RCMP's National Security Information Line.
To report a non-immediate threat to national security, please e-mail or telephone CSIS.
Please complete our form below. Your information will be sent securely.
You can write to us in both of Canada's official languages.
