You can't chose just 1 parent. You need to include both of them. Your father can be declared as not accompanying dependant of your mother (and not to come to Canada), but you'll be asked to provide proof that you meet income requirements for sponsoring both of them and he'll need to be medically examined. I'm sorry for bringing bad news.they married and live together. reason i sponsor my mom in 2019 only because if i apply both my parents my income short a little.
