My understanding is my application starts from the time CPC-M received, from that the days and months is already running until 6months, that's my understanding to the website of Canada Embassy - Philippines
saying that :
Spouses/Common-law Partners/Dependant Children
Within 6 months from receipt of a completed application from the Case Processing Centre in Mississauga (Canada).
Please be aware that processing delays may occur if further medical examination, an interview or additional documents are required.
