Closed for business dates

In case of an emergency, the Canadian Intellectual Property Office (CIPO) will attempt to remain open for business and ensure that essential service to our clients continues with the least possible disruption or delay.

Whenever CIPO is closed for business, including closures due to extraordinary circumstances, CIPO considers all time limits to be extended until the next day that it is open for business. In such situations, mail delivered to CIPO will be considered to be received on the date that CIPO reopens for business, with the exception of correspondence addressed to the Registrar of Topographies.

Time period extensions resulting from CIPO office closures.
