Correcting obvious errors on a registration

From: Canadian Intellectual Property Office

Publication Date: June 17, 2019

This notice is intended to clarify the practice of the Trademarks Office with respect to the correction to an obvious error in the register under subsection41(3) of the Trademarks Act (the "Act").

Subsection 41(3) of the Act gives the Registrar the authority to correct an obvious error in an entry in the register for a registered trademark. The error must be obvious in view of the documents on file. An example of an obvious error that the Registrar may correct would be where certain goods or services, that were in the application on the day on which the trademark was registered, were omitted from the register entry. Another example would be where the Office makes an error in entering an amendment to the goods or services requested by the registered owner under paragraph 41(1)(c) of the Act.

Please note that the correction must be made by the Registrar within six months from the day on which the trademark is registered or when the entry is made on the register. As such, registered owners must ensure that any request to correct an error is received by the Registrar in a timely fashion as requests sent at the end of the period may not be processed in time. Furthermore, requests for these types of corrections should be addressed as follows and sent by mail or fax:
