A web search on the term 'moto z play nougat update canada' indicate a number of articles dated this past week indicating the roll out was just starting. It has not likely been available to Canadian Carriers until recently.
@Agnew Some Canadian carriers are just pushing the OTA update today. Never compare the US release with Canada (everyone needs to remember this) Canada is ALWAYS delayed getting the updates. Sure it won't be to much longer, providing there is no issues with the release on the device..
