Yes, Telus has been testing 5G networks for about a year now. The best place to learn about what's happening is at sites such as iPhone In Canada, or Mobile Syrup.
2022-2024 is more than likely Canada's ETA for true 5G. Whether or not Rogers does what AT&T did with the whole "5GE" mess they are being sued over... We shall see. Changing the 4G LTE icon to 5GE though isn't how 5G works. 😛
