So you need to check Canadian adoption and surrogacy laws, and should be working with an immigration lawyer too. Canada does not recognize some countries for international adoption. It gets complicated on who is the biological parents.
Being PR, you cannot sponsor the child for PR from outside Canada. You need to be inside to sponsor for PR. Do you meet RO? So you will need to either return to Canada, or wait in the country, get passport, and try and apply for the child’s TRV. Most likely refused, so decide on whether to return to Canada and apply for PR. You must wait in Canada during the process. Or try for TRP. Overall the process will take a long time.
