I was reading the sponshorship of a spouse outside of canada and they said that if your sponsored spouse or the sponsor was previously in common-law relationship they must submit a declaration of severance in common-law relationship. I did not submit this when I send my application to CIC-mississauga. I only submitted an income tax return T-4 that shows I was not living anymore with my ex girlfriend.That was my only proof that I was living alone since 2007.Because right now my wife received a letter asking for a passport and NSO certificate of no marriage from the manila visa office.Do you guys think I still need to provide this even if the letter did not ask for it.Please help because I don't know where to get this declaration of severance in common-law relationship letter.I am here in canada and my wife is in the philippines.
