I don't understand gate keeping this feature and would sign up for Pik TV without hesitation. I have chromecasts (with Ethernet) on all our TVs at home and don't feel like buying an Nvidia Shield or Apple TV.
Agree @MetalFaceDoom it's frustrating as a Chromecast owner. You can work around it by using the channels app (like global, CTV etc) and logging in with Telus. But honestly I just want it to work. It's is definitely hurting their viability and with the new Chromecast Android TV it is different from Appletv Integration functionally.
