We applied for sponsorship under common law, but throughout my Sponsor's PR application, we were under the impression that we fall under the (Single/Never Married) category hence we didnt add me as common law partner in her application, I had my own EE profile which I have been re-sitting for IELTS to improve my points for ITA, it was only after Sponsor's PR application that we realized we are common law partners under the canadian law, my partner and I grew up in a country common law partnership is neither recognized nor practiced! As such we had no idea.
IRCC have validated all our documents and deemed valid, their only concern is why we didnt notify IRCC when we completed 12mnths of cohabitation (if we knew about common law we would have used the same documents we submitted to update IRCC during the course of her PR application, webform is one click away!
Please advise me on the best way to approach this
