No, there is a blend. At a big location like Lacolle you will get a very significant commercial throughput. At some of the smaller crossings I think it's fair to say that the commercial throughput is much less but not nil. It varies from crossing to crossing, depending on whether it's a main highway arterial or there's close proximity to commercial entities on either side of the border.
