Similarly, I'm thinking of the circumstances in which a U.S. officer might think a search is necessary and the rules say that they cannot conduct that search themselves, that they have to contact someone at CBSA to do the searching. If you were to apply the new set of rules—slightly changed from what existed before—to the experience over the last 60 years or so, there would not have been one incident when there would have been a problem for a Canadian traveller.
I appreciate the concern of people who want to make this absolutely boilerplate in terms of the protection of Canadian rights and freedoms. We all want to achieve that objective, but the experience would suggest that the rate of incidents that could be considered untoward and actually invoke the provisions of the law would be very few and far between.
