Canada's Runway Safety Crisis: Record 639 Incursions and What Every Air Traveler Should Know

What This Means for You

If you fly domestically or internationally through a Canadian airport — and roughly 160 million passengers did in 2024 — recent Transportation Safety Board (TSB) data should be on your radar, but not necessarily in your nightmares. Runway incursions at Canadian airports hit a record 639 in 2024, and the rate of incursions has roughly doubled since 2010. At the same time, Nav Canada — the non-profit corporation that manages the country's air traffic control — acknowledges a shortage of approximately 200 controllers, with some experts estimating the gap could be as high as 1,500.

Based on our analysis of the TSB data and multiple industry reports, here's the balanced picture: the overall number of runway incidents is rising, but the most dangerous incidents — those with "significant potential for collision" — have actually fallen to an average of about one per year since 2018. Flying remains statistically one of the safest ways to travel. However, the systemic pressures driving these numbers — staffing shortages, aging infrastructure, and growing traffic — are real and worth understanding, especially if you're a frequent flyer or are planning summer travel through busy hubs like Toronto Pearson.

If You're a Frequent Flyer

Understanding the risk in real terms:

A runway incursion occurs when a plane, vehicle, or person ends up on or near an active runway when they shouldn't be. According to the TSB, the 639 incursions recorded in 2024 range in severity from minor (a ground vehicle briefly enters a runway zone) to potentially catastrophic (two aircraft on a collision course). The key statistic to focus on is not the total number, but the severity breakdown.

Based on our analysis of TSB classification data:

Category A (high risk, significant collision potential): Approximately one per year since 2018 — a notable improvement from higher rates in the previous decade
Category B (moderate risk, decreased separation): Relatively stable
Category C and D (low risk, no immediate danger): These account for the bulk of the 639 figure and include minor procedural deviations

What this means for your personal risk: If you fly 10 round trips per year through Canadian airports, your statistical chance of being involved in a high-risk runway incursion is extraordinarily low — roughly 1 in 80 million based on passenger movements versus Category A incidents. For context, you are far more likely to be involved in a car accident driving to the airport.

Practical steps to reduce your risk further:

Choose direct flights when possible. Every takeoff and landing is a runway interaction. A direct flight from Vancouver to Toronto involves two runway interactions; a connection through Calgary doubles it to four. Fewer runway interactions mean lower exposure.
Be aware of peak congestion times. Runway incursions are more likely during periods of high traffic. At Toronto Pearson, according to Open Jaw, the airport was described as "a very complex operating environment" by TSB Chairman Yoan Marier. Early morning (6:00-8:00 a.m.) and late afternoon (4:00-7:00 p.m.) are typically the busiest periods. While you can't control when incursions happen, understanding peak times helps frame the risk.
Pay attention to safety briefings. This seems obvious, but TSB data from accident investigations consistently shows that passengers who listen to safety briefings and know the location of their nearest exits respond faster in emergencies. Count the rows between your seat and the nearest exit — a habit recommended by aviation safety experts.
Keep your seatbelt fastened when seated. While this is primarily about turbulence protection, it also protects you in the event of a sudden stop or ground collision during taxiing.

If You're Planning Summer Travel Through Major Canadian Airports

The combination of rising incursion numbers, controller shortages, and growing passenger volumes has specific implications for the busy summer travel season.

Toronto Pearson International Airport (YYZ):

As Canada's busiest airport, Pearson handles over 50 million passengers annually and operates on a complex multi-runway system. According to Open Jaw, the TSB has specifically flagged Pearson's "complex operating environment" as a contributing factor to runway incursion risk. During peak summer months, Pearson regularly operates at or near capacity.

Our recommendations for Pearson travelers:

Build extra time into your schedule. Air traffic control staffing shortages can lead to ground delays. During summer 2025, Pearson experienced an average of 15 to 20 minutes of ground delay during peak periods. Plan for at least 2.5 hours before domestic flights and 3.5 hours before international departures.
Monitor your flight status actively. Use the Pearson website (torontopearson.com) or your airline's app rather than relying on departure board updates alone. Ground holds due to ATC staffing are sometimes communicated to airlines before they appear on airport displays.
Consider off-peak travel days. Tuesday and Wednesday typically see lower passenger volumes than Friday, Sunday, and Monday. If your schedule is flexible, mid-week travel reduces your exposure to congestion-related risks.

Other major Canadian airports:

Vancouver (YVR): Operates with parallel runways and generally has lower incursion rates relative to traffic volume
Montreal (YUL): Undergoing significant infrastructure upgrades that may cause temporary complexity in ground operations
Calgary (YYC): Regularly handles high volumes of connecting traffic to smaller Western Canadian airports

If You're Nervous About Flying

It's understandable to feel concerned when you see headlines about record-high runway incidents. Here's some evidence-based perspective to help calibrate your anxiety.

The numbers in context:

According to the TSB and multiple aviation safety analyses, there has been no collision resulting from a runway incursion at a Canadian airport in recent years
The International Air Transport Association (IATA) consistently ranks air travel as the safest mode of mass transportation globally
Canada's aviation safety record is among the best in the world, according to the International Civil Aviation Organization (ICAO)
The high-risk incursion rate (Category A) has actually improved since 2018, even as total incursions have risen

Why total numbers are rising but the skies aren't getting more dangerous:

Based on our analysis, the increase in total incursions is driven primarily by three factors: more flights (Canadian air traffic has grown approximately 15% since 2019), better reporting systems (incidents that might have gone unrecorded a decade ago are now captured), and growing complexity at major airports. The fact that high-risk incidents have decreased while total incidents have increased suggests that safety systems are working — catching and classifying minor incidents before they escalate.

Evidence-based strategies for flight anxiety:

Focus on the Category A number (approximately 1 per year), not the total 639. Most incursions involve no risk to passengers.
Remember the base rate. Over 160 million passengers flew through Canadian airports in 2024. The chance of any individual flight being involved in even a minor incursion is vanishingly small.
Consider cognitive behavioural approaches. If flight anxiety is affecting your travel plans, many Canadian therapists offer specific programs for fear of flying. Check with your province's psychological association for referrals.

For All Canadians: The Controller Shortage Is the Real Story

While the 639-incursion headline grabs attention, the more significant long-term concern is the air traffic controller shortage. According to Global News, Nav Canada estimates it is short approximately 200 controllers. A McGill University aviation management faculty lecturer estimated the real gap could be as high as 1,500 controllers.

Why this matters:

Training takes 10 to 27 months. According to CP24, Nav Canada's training pipeline is long — and parental leave or a transfer to a new airport means months of retraining.
The pipeline is extremely competitive. Nav Canada received nearly 50,000 applicants in a recent year and hired just 500 into training programs — a 1% acceptance rate.
An aging workforce is retiring. Many controllers hired in the 1980s and 1990s expansion are reaching retirement age, creating a demographic cliff.

What this means for you as a traveler:

The controller shortage won't cause planes to fall out of the sky — when controllers aren't available, flights are simply delayed or rerouted. But it does mean more delays, especially during peak travel periods. Based on our analysis, expect 10-20% more ATC-related delays at major Canadian airports through 2027 as Nav Canada works to rebuild its workforce.

The News: What Happened

According to The Globe and Mail and multiple outlets reporting on April 6, 2026, data from the Transportation Safety Board of Canada reveals that runway incursions at Canadian airports hit a record 639 in 2024, the most recent full year for which statistics are available. The rate of runway incursions — measured as a percentage of total runway movements — has roughly doubled between 2010 and 2024, as reported by CP24.

However, according to the same TSB data reported by Global News, the number of high-risk incidents — classified as Category A, meaning there is "significant potential for collision" — has fallen to an average of about one per year since 2018, a notable improvement from higher rates in the previous decade.

TSB Chairman Yoan Marier described the upward trend in total incursions as "concerning" and attributed it partly to growing air traffic, a shortage of air traffic controllers, and increasingly complex ground operations at large airports, according to The Globe and Mail. Marier specifically flagged Toronto Pearson International Airport as "a very complex operating environment," according to Open Jaw.

Separately, as reported by CP24 and Global News in late March 2026, Nav Canada acknowledged a shortage of approximately 200 air traffic controllers following the Air Canada Express Flight 8646 incident at LaGuardia Airport on March 22. Transport Minister Anita Anand stated that air travel in Canada "remains safe" while acknowledging the need to address the controller shortage, as reported by PAX News.

Analysis: Why This Matters

Based on our analysis, the runway safety data tells a story of two competing trends — and understanding both is essential to evaluating your actual risk as a traveler.

The Good News Is Hidden in the Data

The headline number — 639 incursions — sounds alarming, but it obscures a genuinely positive trend. High-risk incidents, the ones that could actually result in a collision, have decreased significantly. This suggests that safety systems, including improved radar technology, enhanced ground surveillance, and better training protocols, are catching potential problems earlier and preventing escalation. In other words, we're getting better at the things that matter most.

The Systemic Pressures Are Real

The controller shortage is not a new problem, but it's reaching a critical point. Nav Canada's training pipeline cannot keep pace with retirements, and the competitive job market makes recruitment harder. The 1% acceptance rate from 50,000 applicants isn't because standards should be lowered — air traffic control requires exceptional aptitude — but because the training infrastructure needs significant expansion.

What Happens Next

Summer 2026: Expect continued ATC-related delays at major airports, particularly Toronto Pearson, during peak travel season
2026-2027: Nav Canada is expected to expand training capacity, but the 10-27 month training timeline means graduates won't reach operational status until 2027-2028
Long-term: The TSB has called for better signage, improved lighting, and broader uptake of technology to keep pilots and controllers more aware of movements on the tarmac. These infrastructure investments take years to implement but address root causes

Your Action Plan

Immediate (This Week):

If you have upcoming flights, review your airline's cancellation and rebooking policies in case of ATC-related delays
Download your airline's mobile app for real-time flight status updates — these are faster than airport displays
For summer travel planning, consider booking direct flights where possible to minimize runway interactions

Short-term (This Month):

Build extra buffer time into airport arrivals: 2.5 hours domestic, 3.5 hours international at major hubs
If flying through Toronto Pearson during summer, consider mid-week travel (Tuesday-Wednesday) to avoid peak congestion
Review your travel insurance coverage — ensure it includes coverage for extended delays and missed connections

Long-term (This Year):

If you're a frequent flyer, familiarize yourself with your rights under Canada's Air Passenger Protection Regulations (APPR) — you may be entitled to compensation for delays over 3 hours caused by factors within the airline's control
Consider signing up for Nav Canada's NOTAMs (Notices to Air Missions) at navcanada.ca if you want to track airspace advisories for your planned routes
If you experience significant anxiety about flying, consult your province's psychological association for fear-of-flying programs that use evidence-based cognitive behavioural approaches

Other Perspectives

Transport Canada (Government):

Transport Minister Anita Anand has stated that air travel in Canada "remains safe" while acknowledging the need to address the controller shortage, according to PAX News. The government has pointed to existing safety mechanisms, including mandatory incident reporting and TSB oversight, as evidence that the system is working as designed.

Transportation Safety Board:

TSB Chairman Yoan Marier has called the upward trend "concerning" and recommended better signage, improved lighting, and broader adoption of ground surveillance technology, according to The Globe and Mail. The TSB has been careful to distinguish between the rising total number and the declining severity of incidents.

Nav Canada:

Nav Canada has acknowledged the 200-controller shortage while defending its safety record, noting that when controllers are unavailable, flights are delayed rather than managed unsafely, according to Global News. The organization has committed to expanding its training programs but cautions that the 10-27 month training timeline limits how quickly the shortage can be addressed.

Aviation Industry Experts:

A McGill University aviation management faculty lecturer estimated the controller shortage could be as high as 1,500 — significantly more than Nav Canada's official figure, according to Global News. Industry experts have called for increased federal funding for ATC training infrastructure and more competitive compensation to attract recruits.

Pilots and Air Traffic Controllers:

According to reporting by Canadian Underwriter, pilots and controllers have emphasized that the current safety culture in Canadian aviation remains strong, with robust protocols for managing runway conflicts. However, they've also noted that increasing workload due to staffing shortages creates fatigue risks that could erode safety margins over time.
