Yes, I recently looked at this question again, because I was getting a few more complaints than in the past.
Let's look at the numbers first. The first point that's made—not here, but it's one I get all the time—is that we are turning more people away for that reason, for driving under the influence. But no, we are not. In terms of the people who are turned away, the numbers on that kind of thing are reducing as opposed to increasing.
Now, we're working with the law, with IRPA, and the law is fairly specific about admissibility into the country. Anything that is criminal makes one inadmissible to the country, if you are not Canadian. There are a few things an officer can do to deal with that...of course, the difference being is that it's illegal in Canada and not in the United States.
