Prime Minister Justin Trudeau’s government joined Canada’s closest intelligence allies in banning Huawei Technologies Co. from fifth-generation wireless networks.

The Chinese state-championed telecommunications firm poses a threat to Canada’s national security, Industry Minister Francois-Philippe Champagne said Thursday, confirming an earlier Bloomberg News report. ZTE Corp. equipment will also be prohibited.

Firms that already have Huawei or ZTE gear installed will have to remove it, Champagne said. Trudeau’s government had delayed the decision for more than three years, as relations between Canada and China deteriorated, and a ban would almost certainly stoke tensions.

The long-awaited announcement will be welcomed by President Joe Biden’s administration, which has sought to steer countries away from Huawei. American officials allege its gear could allow the Chinese government to interfere with 5G networks. Since 2019, the US has imposed what may be the strongest sanctions it has ever placed on a single company.

Relations between the two nations soured dramatically after Canada’s arrest of Huawei Chief Financial Officer Meng Wanzhou on a U.S. extradition request in December 2018. China imprisoned two Canadians, former diplomat Michael Spavor and entrepreneur Michael Kovrig, within days of Meng’s arrest.

The high-stakes standoff was resolved last September after the U.S. struck a deferred-prosecution deal with Meng, allowing her to return to China and for the two Canadians to come home.

But the feud has left hard feelings. Thursday’s announcement comes only three days after lawmakers voted to revive a special committee to study the country’s ties with China. On Wednesday, the Canadian government announced that China had lifted restrictions on canola imports.

The move, however, should not pose big challenges for companies like BCE Inc. and Telus Corp. that have used Huawei equipment. Fearing an eventual ban, the two companies have already begun to exclude the state-championed Chinese firm from their 5G build-outs.

Huawei long played a key role in Canadian wireless networks. It won its first major North American project from BCE and Telus in 2008 — a pivotal contract that helped cement the Chinese provider’s reputation as a global player that could compete on quality. The deal paved the way for it to become a major supplier to Canada’s biggest telecom companies over the next decade.

In the lead-up to the decision, Canada’s military leadership argued the company posed too big a potential security risk to allow it into 5G networks. The nation’s human and signals intelligence agencies, however, were reportedly split on how best to deal with Huawei.

Canada’s biggest wireless provider, Rogers Communications Inc., has partnered with Huawei rival Telefonaktiebolaget LM Ericsson on 5G. The Toronto-based firm’s vice chairman argued in 2019 that the Chinese giant posed too big a security risk to be allowed into the future network equations.

5G technology could end up being 100 times faster than existing top-of-the-line networks, with data speeds reaching 10 gigabits per second. That would greatly improve the ability of consumers to stream high-definition video and also help build out the so-called “internet of things” that can link everything from household appliances to traffic lights.

In July 2021, Canada’s telecom firms committed to paying $8.9 billion to buy licenses for 5G airwaves in a record-smashing government auction. Rogers, which is in the midst of trying to buy smaller rival Shaw Communications Inc., led the way with a $3.3 billion spectrum purchase.
