Air traffic control deficiency impacting Canadian airport operations

In a concerning development, Canada's air traffic control system is grappling with a significant staffing shortage. This issue, exacerbated by the COVID-19 pandemic, has led to temporary service interruptions at major airports such as Vancouver, Calgary, Toronto, and Montreal.

The International Civil Aviation Organization (ICAO) includes air traffic control in its definition of safety operations. This underscores the importance of a well-staffed air traffic control workforce for the safety and efficiency of air travel.

NAV Canada, the organization responsible for Canada's civil air navigation system, has announced these interruptions due to staffing constraints. To address the shortage, NAV Canada is recruiting, training, and licensing new controllers at an increased pace to add capacity where possible. As of 2023, approximately 230 air traffic controllers have been qualified for work through training at NAV Canada's seven schools across the country. Currently, over 500 air traffic controllers are in training.

The pandemic has played a significant role in the staffing shortage. Many air traffic controllers have taken retirement packages, while the preparation of new recruits has been stymied due to social distancing and the drastic decrease in flight volumes.

The staffing shortage in Vancouver was resolved early Wednesday morning, but it created a backlog of delays that took additional days to clear. On Tuesday, Vancouver International Airport experienced a significant number of flight cancellations and delays, with nearly 100 flights cancelled and 195 delayed.

In the event of an unexpected last-minute staffing shortage at air traffic control towers, safety protocols require NAV Canada to reduce the volume of aircraft coming into the airport, leading to fewer arrivals on time. Until the labour shortage is resolved, air traffic controllers will always prioritize safety over service continuity in the event of an unexpected staffing issue.

The Canadian Air Traffic Control Union (CATCU) announced temporary work stoppages at airports in Vancouver, Calgary, Toronto, and Montreal. The personnel shortage is not expected to be fully resolved in the near future.

The salary of trainees for air traffic controllers in Canada is around $60,000 annually, compared to upwards of $200,000 after earning a seat in a control tower. This discrepancy in salary may be a factor in the staffing shortage, as the industry competes with other high-paying professions for talent.

Addressing this issue requires "short, medium, and long-term solutions," according to Nick von Schoenberg, president of the Canadian Air Traffic Control Association. Pushing controllers harder is not the solution, he emphasized. A safety audit by the International Civil Aviation Organization in 2023 found that Canada's safety operations were scored at nearly 22% effective, 50 points below the global average.

NAV Canada is taking every step needed to support safe and efficient service continuity across the country. Mitigating impacts to travellers will require careful planning and coordination to ensure the safety of all involved.
