In Canada, there is no legal obligation to use the ® , TM, MC or MD symbols. It is however recommend to use ® (registered trade-mark) or MD (marque de commerce déposée) in association with your registered trade-marks. Symbols TM (trade-mark) or MC (marque de commerce) can be used in association with your other trade-marks whether an application has been filed or not. These symbols remind consumers and your competitors that you are the owner of the trade-marks in question.

     

    It is also advisable to inform the public that the trade-mark is used under license. Often, we see an asterisk next to the mark with a reference to the effect that the trade-mark is owned by a person under license. For example, "ABC trade-mark is the property of ABC inc. used under license. "
