Thank you for sharing your situation and question with us.
We can appreciate that you would be interested in what your options are in this situation.
You can find some information on the Immigration, Refugees and Citizenship Canada (IRCC) website in the Requirements to sponsor a child section.
You may want to contact the IRCC Call Centre to speak to a representative for some additional information.
We suggest that it is important and probably best that you speak to a Lawyer who is familiar with Canadian immigration issues for additional information regarding your family situation.
