These lists provide the following information on productions for which a Canadian film or video production (Part A) certificate (defined in subsection 125.4(1) of the Income Tax Act) was issued: The title of the production for which the certificate was issued, and the name of the taxpayer(s) to whom the certificate was issued. Where a production is a series, note it is possible that not all episodes were certified. Approximately every six months, the list of certified productions since 2010 will be withdrawn and replaced with a new update to report the addition of newly certified productions and the removal of revoked productions.
