## Description

Cargojet anchors operations at John C. Munro Hamilton International Airport (IATA: YHM, ICAO: CYHM), running its principal sorting and transfer network from the site alongside DHL Express, UPS, Purolator, Canada Post and Amazon Air. Together these carriers moved roughly 750 million kilograms of billable cargo weight through YHM in 2025, confirming its status as Canada's busiest airport for domestic overnight express freight. Because Hamilton faces few of the night-time movement limits that constrain nearby Toronto Pearson, freighters can work around the clock. A jointly funded expansion programme worth about CAD 46.9 million is enlarging the airfield, raising gate capacity by roughly 125 per cent and de-icing capacity by 250 per cent, adding a dedicated service road and doubling parking capacity for Cargojet's Boeing 777 freighters. Recent investment also added cold-storage capacity for temperature-sensitive shipments, while KF Aerospace builds facilities for widebody freighters. On the ground, Highway 403, the QEW and Highway 6 link the airport to the Greater Toronto Area and the Niagara border crossings, and the Port of Hamilton on Lake Ontario plus the CN and CP rail corridors add multimodal depth. Passenger service remains the smaller side of the business, though it is growing with Porter Airlines' entry.
