Focus on Canada and the United States
In June 2025, transborder passengers accounted for 24.7% of the total number of screened passengers, down from 26.7% in June 2024.
Transborder traffic is typically concentrated at the four largest Canadian airports: Toronto/Lester B. Pearson International, Vancouver International, Montréal/Pierre Elliott Trudeau International and Calgary International. Combined, these four airports represent more than 90% of all transborder traffic.
In June 2025, Calgary International posted a 4.3% year-over-year increase in screened passenger traffic to the United States, breaking a four-month-long streak where the four largest airports saw lower passenger counts than in the same month of the previous year.
Meanwhile, Toronto/Lester B. Pearson International (-7.9%), Vancouver International (-0.5%), and Montréal/Pierre Elliott Trudeau International (-4.8%) posted year-over-year decreases in transborder traffic in June 2025.
Note that screened passengers include both Canadian and non-Canadian residents.

Note to readers
Data for this release are derived from the Canadian Air Transport Security Authority (CATSA) Boarding Pass Security System and include screened traffic at pre-board security screening checkpoints at the eight largest airports in Canada.
The eight largest airports in Canada are Halifax/Robert L. Stanfield International, Montréal/Pierre Elliott Trudeau International, Ottawa/Macdonald-Cartier International, Toronto/Lester B. Pearson International, Winnipeg/James Armstrong Richardson International, Calgary International, Edmonton International and Vancouver International.
Screened passenger traffic includes air travellers required to go through pre-board security screening and excludes aircrew and airport employees. This data series represents a different measure of traffic than the counts of enplaned or deplaned passengers published in Statistics Canada's annual Airport activity report or produced by the individual airports. For example, the screened passenger data will not account for passengers with connecting flights who did not pass through security. For more information, please refer to the "Related information" tab (Definitions, data sources and methods) for this release.
Users interested in accessing daily counts of screened traffic at Canada's major airports can obtain them from the CATSA website.
