Bell, which is Canada's biggest mobile provider, said it would use equipment from Ericsson for the core of its 5G network, with Nokia to supply gear for other parts of the rollout.
Telus also picked the two firms, the only two in the world that can supply gear for an end-to-end 5G network apart from global leader Huawei and its Chinese competitor, ZTE Corporation.
Canada's other big telco, Rogers Communications, has already said it would be using equipment from Ericsson.
The US has been on a crusade for the last few years, asking countries not to use the company's gear, claiming that it is a security risk, but providing no proof to substantiate these claims.
Huawei, a privately-owned firm, has constantly denied these allegations to no avail.
Both Ericsson and Nokia make most of their gear in China, in partnership with state-owned companies.
Ericsson Panda has as one shareholder the state-owned Assets Supervision and Administration Committee, while Nokia Shanghai Bell is a joint venture with state-owned China Huaxin Post & Telecommunication.
