Once arrived they are ours to keep unless a refugee claim is refused. They are still ours until those who are refused are deported. Good luck with that. If refused many disappear and remain illegal living and working. If they can avoid deportation, usually with the help of taxpayer funded lawyers plan B, start a family and have kids who are Canadian. The next move is the heart rending media plea about the cruelty of deporting and breaking up a family or that they will face death, rape or other inhumanity if returned to their country of origin, if known. So the simple answer is hire more Government Immigration staff. Triple the number of refugee board adjudicators. Build thousands of subsidized homes, education facilities and fund refugee support organizations.  To pay for this just increase personal and business taxes, stop whining and complaining and bask in the knowledge Canada and Canadians will be internationally praised as being compassionate, kind and caring. Sunny Ways for ever.
