In view of the continuing unforeseen disruption caused by the COVID-19, the Canadian Intellectual Property Office (CIPO) has announced all deadlines on IP matters under the Patent Act, Trademarks Act and Industrial Design Act falling between April 1, 2020 and ending on April 30, 2020 will be extended to May 1, 2020. CIPO has again confirmed that further extensions may be possible as the pandemic situation evolves. The CIPO announcement link is as follows for your reference:
 
In addition, in all proceedings before the Trademarks Opposition Board (TMOB), for deadlines falling after April 1, the Registrar will consider the disruption caused by COVID-19 a sufficient circumstance to obtain an extension of time upon request. The Registrar may also use its discretion to extend deadlines on its own initiative if it is in the interests of justice to do so.
