We are not involved in the processes Mr. Gallivan mentioned, namely pressuring people to co-operate and informing them of the possible consequences if they do not, including the fact that they will not be able to return to Canada for five years.
I think the most effective approach for us would be to let IRCC manage the program. As we have said, we can search our data to determine whether certain individuals are in the country. However, we really want the shortest list possible, after the department has done all its work.
