As you mentioned, there was a cargo pre-clearance pilot under the beyond the border agreement. The initial testing phase was done in B.C., and there was a second phase in Ontario.
At this point, there are no specific sites identified for cargo pre-clearance. We are beginning to explore, within Canada and in discussions with U.S. colleagues, our objectives for cargo pre-clearance, some of the legal or procedural requirements, and specific sites where cargo pre-clearance may make sense. Ultimately, as with pre-clearance generally, it is driven by the economics of where it makes sense economically and where it's feasible in terms of border operations.
The short answer is that no specific sites have been identified yet.
