If you are applying for family sponsorship via Québec, there was a recent change in procedures for Quebec family class applications, which was implemented by the Quebec Ministère de l'Immigration des Communautés culturelles (MICC). It looks like you will now need to fill out the MICC undertaking kit and submit it to the MICC along with a copy of the letter issued by CPC (instead of having CPC-M submit the documents directly)
