I am having same issue how did you go about this.. I was already in Canada before I got my pr as a student but didn’t know I have to inform cic of marriage .. the marriage was during my pr processing time
I got my PR while already in Canada, during the time waiting I got married and didn’t know I was meant to inform ircc ..now I was reading on spousal sponsorship and seeing I was meant to inform ircc.. is there anything I can do
