In December 2016, the Canadian Intellectual Property Office (CIPO) will begin sending courtesy notices inviting owners of registered trademarks to submit Nice classifications for the goods and services listed in the registration(s). The notices are in response to amendments to the Trade-marks Act that are projected to come into force in 2018.  The amendments will require applicants to classify goods and services according to the Nice classification system.  Since it remains unclear as to when the amendments requiring Nice classifications will come into force, the notices will not include a response deadline. The notices are to be sent to registered owners of trademarks that are subject to renewal as of 1 January 2018.
