Yes, you must pay the application fees for both of your parent. And both of your parents must pass medical exam too. Once your application is completed (when you parents are approved as Permanent resident) your father can decide to live outside or in Canada.I do meet the income requirements for both parents. it's just that my father won't be accompanying my mother so she is the principal applicant and my father is the on the application as a non accompanying dependant. I am just confused about the application fee as if I have to pay 1040 for each of them or only for my mother
There is no option, according to IRCC requirements, that allow a single parent while in legal marriage and alive, to be separated from the other.
