I got a request letter from IRCC requesting to prove my relationship with my wife, It was a questionnaire with questions like, date of marriage, when did we meet, photos before and after marriage and honeymoon picture, social media posts, etc. I was shocked to see this request as my wife is already with me in Canada and already proved my genuineness when I applied SOWP for her 1 year back. Please try to collect these documents if you have time or I would advice to get this doc uploaded while applying PR to avoid unnecessary questions or delays. I was married very recently in 2023, this might be the reason for request
