I was also a member of the opposition. I understand your approach to asking questions and you're quite good at it.
However, you're right about the opening hours at some border crossings. I understand that the agency's president answered this question while I was at a cabinet meeting. I also answered a question on this topic from one of your colleagues in the House of Commons. The opening hours have been aligned with the hours at our American partners' border crossings.
This topic has been the focus of discussions for months, if not years. The idea is to increase security. For example, if the Americans unilaterally close their side of the border for certain hours and an individual crosses the border, the safe third country agreement states that the individual could be apprehended and sent back to the United States. However, if no one is at the border crossing on the other side of the border, should the individual be taken to a Quebec provincial police station in a small town in Quebec?
Standardized opening hours are one way to increase security. The Canada Border Services Agency has been having these types of discussions with its American partner for a long time. I've been assured that this doesn't affect border security in any way.
