Sorry, I cannot type Japanese now. Child support is the right of the children. It is not the parent. Therefore it does not make a difference whether you are married or in a common-law relationship. Your child support rights and obligations on separation in Canada are the same, I believe.
Also child custody is determined according to what is in the child¡Çs best interests. Again, it does not make a difference from marital status. Child custody is also determined the same way upon separation in Canada.
