Back to Consumer resources

Telecom providers and industry partners are working to protect Canadians from fraud through advanced security measures, consumer education, and collaboration with law enforcement.

Investment in network level processes

Telecom providers are working behind the scenes to protect Canadians by investing in advanced security processes, engaging in the development of new measures, and partnering with law enforcement.

• Call Blocking: Universal Network-Level Call Blocking (UNLCB) is one tool telecom providers use to help protect Canadians against certain unwanted calls by blocking calls with blatantly false call display data. Calls with invalid numbers are automatically blocked, such as numbers like 000-000-0000 and others that don’t conform to international numbering plans.
• Caller ID Authentication (STIR/SHAKEN): STIR/SHAKEN protocols help protect Canadians from spoofed calls by verifying the authenticity of caller ID information. These protocols use digital certificates to confirm that a call is actually coming from the displayed number and has not been altered in transit.
• SPAM Filters (text and email): Telecom providers also use various spam filters to protect consumers from unwanted text messages and emails. These filters detect and block phishing attempts and mass spam campaigns, and help reduce the spread of phishing scams, promotional spam, and other unwanted messages.
• Block-listing: Block-listing keeps messages from known scam numbers and email addresses from reaching consumers by automatically blocking or flagging them as suspicious. Block-listing helps reduce the volume of unwanted communications, complementing other security measures such as spam filters and call authentication protocols.

Fraud prevention teams

Telecom providers have dedicated teams specializing in fraud prevention, detection, and rapid response to emerging threats. These experts use advanced analytics, artificial intelligence, and real-time monitoring to identify suspicious activity and take steps to protect customers from scams. They work closely with law enforcement, regulators, and industry partners to stay ahead of evolving fraud tactics.

Consumer education

Telecom providers’ information helps consumers recognize scams and take proactive steps to safeguard their personal and financial information. Through their websites, social media, and customer communications, carriers provide up-to-date fraud prevention tips, alerts about emerging threats, and guidance on spotting suspicious activity. By equipping Canadians with relevant knowledge of scams and risks, consumers are better able to protect themselves.

Collaboration with government

Telecom providers also work closely with government agencies, law enforcement, and cybersecurity organizations—such as the Canadian Cyber Threat Exchange (CCTX), and the Canadian Security Telecommunications Advisory Committee (CSTAC)—to develop industry-leading fraud prevention strategies. These partnerships help identify emerging threats and disrupt fraudulent activity.
