DHS Secretary Janet Napolitano was pressed on pre-clearance for the Peace Bridge border crossing:
“Representative, I will be very clear. We have looked into preclearance on the Canadian side. We cannot do it. The position has not changed. When and if the bridge and the facilities are expanded on the U.S. side we are fully prepared to provide the staffing and support for that on the U.S. side. We understand the importance of the span for trade and tourism and so forth. But we are not going to be able to resolve the preclearance issues in Canada.”
