I like your question.
This is my answer. I've been doing this for 22 years. That's as long as the lifers have been in the bureaucracy. The immigration officers are there for their careers, and they move up through the ranks and become directors, directors general, assistant deputy ministers, and so forth. They're there for their entire careers.
The ministers just come and go. They're there for eight months sometimes, ten months, twelve months, fifteen months, two years. Very few last longer than three years—very, very few.
So it's the top brass in the department who develop their ideas on what kind of program, what kind of Canada, they want to have. Let's not forget that.
