To accelerate the innovative technology in CanadaBell has also partnered with Western University to create an advanced 5G research centre, including the deployment of a campus-wide 5G network.

"With 5G coverage that is 6 times greater than the next largest network, the biggest selection of 5G-capable devices available and faster data speeds than even our award-winning Advanced LTE network, Bell Mobility has once again raised the bar in Canadian wireless," said Claire Gillies, President of Bell Mobility.

"As the scale, speed and capabilities of our next-generation network continue to grow, Bell Mobility will champion the 5G customer experience in every part of our business."

Now, Bell 5G customers in Montréal, the GTA, CalgaryEdmonton and Vancouver will have access to enhanced mobile data speeds and faster response times, as well as seamless connections to Bell's national LTE network – which reaches 99% of the Canadian population and already offers data speeds that independent analysts have found rank with the fastest in the world.

According to the company, the high capacity and near-instant connections offered by mobile 5G will support a virtually unlimited range of new consumer and business applications in coming years, including virtual and augmented reality, artificial intelligence and machine learning, connected vehicles, smart cities and enhanced rural access, and unprecedented IoT opportunities for business and government enterprises.

Rival telecom company, Rogers Communications Inc., activated its 5G network earlier this year in downtown Vancouver, Toronto, Ottawa and Montreal.
