We tried 3 times, refused, the most recent after submitting spousal sponsorship. I am a Canadian citizen with a newborn child, just born very recently. In spite of getting a doctor's letter and MP letter requesting my husband to be here to help me, they still refused my husband's visa. They don't care if a new mother goes into postpartum depression and commits suicide, they won't give a visa. Thankfully not the case for me but that's how heartless they are. Wish you the best anyway, make sure you do everything possible to show the applicant will go back. Btw we haven't got our AOR1 yet so dunno if that makes a difference.
