In this process with CBSA, when you get hired, it takes about three months within the four-month training process to get the port you're going to, and it's a random process. It's not merit-based. In other words, you can't get to the top of the class and pick the place you want to go. A lot of the postings that are available are very isolated positions, and that's the risk you are taking when you apply to CBSA. That is well known at the beginning of the hiring process, but I think that's why you're probably not getting as many as you'd like coming in the door in the first place.
