Flight delays at Canada’s busiest airports dropped by approximately 85% between May and August 2026 compared to the same period last year, NAV Canada announced. The four major airports involved in this reduction are Toronto Pearson, Montreal-Trudeau, Calgary, and Vancouver International Airport.
Flight Delay Statistics and Flight Volume
The proportion of flights delayed across the four airports decreased sharply from 1.54% in summer 2025 to 0.24% in 2026. Vancouver International Airport recorded the most significant improvement, with delays falling from 4.42% of flights in 2025 to 0.64% in 2026. Despite this increase in punctuality, these airports handled 0.9% more flights in the summer of 2026 compared
to the previous year.
NAV Canada Staffing and Operational Measures
NAV Canada employed over 2,800 air traffic service professionals as of summer 2026. The organization narrowed its air traffic controller staffing gap to roughly 170 vacancies by August 31, down from about 200 in the spring of the same year. To optimize operational coverage during the peak period, NAV Canada temporarily reassigned management staff to frontline roles and rehired more than 50 retired controllers.
Official Statements and Seasonal Context
Marie-Pier Berman, NAV Canada’s chief of operations, said, “Today we can say they upheld that standard through the most demanding stretch of the year.” The busy summer period, including August and Labour
Day, typically puts extra pressure on the air traffic system due to hot weather and increased travel demand. Berman credited the improvement to the dedication of air traffic controllers, flight service specialists, and support teams across Canada.
She emphasized that the staffing rebuild will continue through fall and winter and noted that “readiness has never meant promising that no disruption will ever occur.” NAV Canada’s prior investments and strategic staffing decisions supported the sustained performance through summer 2026.
