Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
The IP address you are now using identifies your location as Canada, and it appears you have a US based Roku account. All you can do is create a new account while in Canada, do a hard reset on your Roku and register it to the Canadian account. It doesn't matter that The Roku Channel is available in both countries. You are out of your account's area, so it will not play US based channels. My guess is TRC has slightly different programs available between US and Canada.
Unless your stay in Canada is temporary, you're best off with an account that matches your location.

It sounds like you may have created a Roku account that isn't located in your current region. If channels in your region are not available, it may indicate that your device is linked to an account that was created in a different region where that channel may not be offered by the channel provider. You'll want to make sure that you are using an internet connection located in the correct region when creating your account. You can check your IP address' reported location by visiting www.whatismyip.com - If you see an issue, you'll need to contact your ISP to help resolve any issue.
We would recommend creating a new Roku account in your region. For more information about how to create a new account, visit our Support page here: How do I create a Roku® account? Once your new account is set up, try to perform a factory reset on your device and link it to your new account.
