在网上帮父母办理旅游签证，是旅游签证，遇到一个问题，
Do you have a
family member who is a Canadian
citizen or
permanent resident and is 18 years or older?
我点击了family member的解释，如下：
An applicant's closest relatives, in the context of an application to CIC. It is defined as a spouse or common-law partner, dependent children, and their dependent children.
我理解family member是配偶，或者是依靠你的孩子或孙子孙女，成年了独立生活的孩子不算，是这样吗？我父母只有我一个儿子在加拿大，我靠自己生活呢。那是不是这里选No?
请问各位填过表的朋友，都是如何处理这个问题的？谢谢谢谢！
