Fifth Generation Wireless Networks (5G)

Background:

5G

Wireless networks are the modern infrastructure on which the global data driven economy is built. The global telecommunications sector is undergoing a transition from fourth generation wireless technology to fifth generation (5G) and looking ahead to sixth generation (6G). 5G networks will operate at significantly higher speeds and will provide greater versatility, capability, and complexity than previous generations. As a result, 5G networks will become a crucial component of Canada’s critical infrastructure. The full implementation of 5G in Canada’s federally regulated wireless telecommunications sector will take several years and began with the 5G spectrum auction in 2020.

It is anticipated that 5G technology will enable applications and innovations that will provide many new economic opportunities for Canada such as those associated with the Internet of Things, smart cities, connected and automated vehicles, and remote surgeries. However, incidents resulting from the exploitation of vulnerabilities by malicious actors will be more difficult to safeguard against, and could have a broader impact than in previous generations of wireless technology. Accordingly, in order to leverage this opportunity for economic growth, the safety and security of the technology must be ensured.

The Government of Canada is conducting an ongoing examination of emerging 5G technology and the associated economic opportunities and security risks. Particular consideration is being afforded to the foreign and defence relations, economic, national security, and technical implications. Public Safety Canada, Innovation, Science and Economic Development Canada (ISED), the Communications Security Establishment (CSE), the Canadian Security Intelligence Service (CSIS), the Department of National Defence, Global Affairs Canada, and the Privy Council Office have been working closely to consider every possible dimension to this complex situation. On September 28, 2021, in comments to the media, the Prime Minister suggested that an announcement on telecommunications security would be made in the coming weeks.

International

The security of 5G wireless networks has been at the forefront of domestic and international media stories. Canada’s Five Eyes partners have all made public announcements on how they plan to protect 5G wireless telecommunications networks. These policies range in specificity from the naming of specific entities to generic statements of intent to bolster security. Most recently, on July 14, 2020, the United Kingdom (UK) announced its decision to ban Huawei from its 5G networks and eliminate all Huawei equipment from UK 5G telecommunications infrastructure by 2027. As of December 31, 2020, it is illegal for UK service providers to purchase new Huawei equipment and they must commit to a timetable for the complete removal of Huawei equipment.

The United States (US) has been Canada’s most vocal partner, strongly encouraging countries to carefully weigh the security considerations of 5G technology. On March 9, 2020, a US delegation visited Canada to hold discussions related to 5G with various ministers and Government officials. The Biden Administration has maintained the US’s international security-focused approach to 5G. Outside of the Five Eyes, several like-minded countries are also carefully considering what equipment will provide acceptable levels of security for their network infrastructure.

Current Network Security

In the context of current 3G/4G/LTE networks, a Canadian Security Review Program is in place to mitigate cyber security risks. CSE actively engages with Canadian telecommunications service providers (TSPs) and equipment vendors to help ensure the security of today’s existing Canadian telecommunications infrastructure.

The program has been in place since 2013, and has helped mitigate risks stemming from designated equipment and services under consideration for use in Canadian 3G/4G/LTE telecommunications networks, including Huawei. To date, this program has led to:

As the Government prepares for the implementation of 5G infrastructure in Canada, the expertise and experience developed through the Security Review Program will be important in assessing cyber threats and risks of emerging technology.
