I found this post while trying to find a way to purchase the Wr001 cord for our streaming stick+. I called the customer service number and spoke to Norman. He advised me that Roku does not ship to Canada. I would need to have it shipped to an American address and then have it shipped to me.
It sucks that Roku doesn't ship to Canada even though they sell their products internationally.
We really enjoy using the Roku streaming stick and are saddened not to be able to continue to use it. If we can't find a way to purchase the cord, we'll have to go with another company for their streaming device.
Please send me a PM (private message) with your Roku account email address, and include the serial number of the Roku device from Settings>System>About along with a summary of the issue you are experiencing. I'll be able to assist you further from there.
