You must answer all questions. If any sections do not apply to you, please answer “Not Applicable.”
It is very important that you list on this form any other children (even if they are already permanent residents of Canada or Canadian citizens) that you, your spouse or common-law partner or your dependent children might have who are not included in your Application for Permanent Residence. This includes married children, adopted children, stepchildren and any of your children who have been adopted by others, or who are in the custody of an ex-spouse or ex-common-law partner.
