There are studies out there that show what the costs would be if an incident happened, accidental or otherwise. I'll use the Windsor-Detroit bridge as an example. Once you get up to two and three hours, you're quickly running into the hundreds of millions of dollars at a border point like that one. We have some very, very busy border points.
There's another thing on the cost. I'm concerned about cost as much as anybody is, but think of it this way. This year, those border officers, in import duties alone, will collect about $3.2 billion. In GST-HST, they will collect about $22 billion. If you wanted to look at it from the point of earning their keep or paying for their operation, the total operation of CBSA this year is going to be about $3.14 billion. That's what it's going to cost to run the whole operation. As I said, in import duties alone they're collecting $3.2 billion, and in GST-HST they're collecting about $22 billion.
