Hi did you got the best answer yet? I came here as acaregiver and got residency.According to the law that applies of becoming a resident here in Canada,a permanent resident can sponsor his/her spouse.Theyre asking for some proof like your cards you send to each other and thelove letters,a proof or a pic that you meet her family and vice versa.The story how you met and proof how you communicate to each other,history of phone call or email.and your marriage contract.You also have to proof that your love is genuine bcoz theyrereally strict now bcoz of what other couple did..an arranged marriage.And also its agood points if your spouse is a skilled worker or know how to work so they are convince shes not gonna be burden of Canada.
