You’ll have spotted one difference off the top: cabinet ministers in Canada are simply appointed by the prime minister. In the U.S., by contrast, these and other senior appointments are made only with the “advice and consent” of the Senate. While the president’s recommendations are infrequently rejected, the confirmation process itself can be contentious and sometimes highly revealing. So yes, it matters what their views are, and it matters whether they can do the job. Occasionally it will be said, after a minister has been dismissed, that he or she was not up to the job.
