About Government Agencies
Two agencies provide passport control and immigration services at YWG. The Canada Border Services Agency (CBSA) is a unified agency that oversees customs, immigration, and food inspection services at any port of entry to Canada. Any passenger arriving from a destination outside of Canada must report to the CBSA for inspection.
United States Customs and Border Protection (USCBP) provides similar services for departures to the United States from YWG. When USCBP processes passengers and baggage in YWG, the process is referred to as "preclearance." In the event a flight were to be processed by USCBP in the United States on arrival, the process is called "post-clearance." The vast majority of US-bound flights from YWG are precleared.
Preclearance has a long history in Canada, which dates back to an agreement from 1952. The relationship between YWG and USCBP is governed by enabling legislation signed between Canada and the United States. The area of the terminal in which USCBP operates is designated by Transport Canada as preclearance area. USCBP can only exercise their authorities within the defined area prescribed by Transport Canada.
Both agencies are customers with unique needs. However, the presence of CBSA and USCBP at YWG enable the airport to handle all type of passenger traffic.
The following section outlines the various government agencies that operate at Winnipeg Richardson International Airport.
Canadian Air Transport Security Authority (CATSA) 
The Canadian Air Transport Security Authority (CATSA) is a Crown corporation reporting to Parliament through the Minister of Transport that provides airport security screening for passengers, baggage and workers in secure areas of airports.
