@deb711 You would need to make that request to the broadcasters as they are the ones who decide to make an app for a particular streaming device. Roku has no control over that. You would need to send your request to CTV local news, Sportsnet and Rogers.
Depending on what you are wanting to watch, you may find other channels for that purpose. Or you may be able to find a subscription package that includes those broadcasters as not all broadcast channels have apps for all devices.
