Aviation · Canada

Aviation counts duty hours. Its people run on sleep.

Pilots, cabin crew and controllers work early starts, nights and time-zone changes. Duty limits cap hours, not sleep obtained, and a fatigue lapse in flight or on the ground can be catastrophic.

Reg Watch

What’s changed, and what’s coming

Regulatory change that affects how you manage fatigue in aviation: what has changed in the last 12 months, and what is on the way.

Recent changeFrom January 30, 2026

Applies across industries in Canada

If you are federally regulated, amendments registered 30 January 2026 add thermal stress duties - controls including work-rest cycles, worker training and committee consultation - in force 30 January 2027.

Read the change

Upcoming changeExpected from January 30, 2027Within 12 months

Federally regulated employers must apply the thermal stress amendments (SOR/2026-10), including the Aviation OHS Regulations, from 30 January 2027. Transport Canada plans to propose Canadian Aviation Regulations safety management system amendments (Canada Gazette Part I) in Fall 2027.

Regulatory changes checked as at October 1, 2026.

Regulation

Who regulates it, and what they expect

Aviation has the most detailed, genuinely fatigue-specific regulation of any Canadian industry researched. Transport Canada sets hard duty limits - generally 9 to 13 hours depending on time of day and flight count, extendable to 15.25-18 hours with an augmented crew - plus mandatory rest of 10-12 hours between duty periods. Rules were strengthened in 2020 for major airlines and 2022 for regional carriers. Airlines can alternatively adopt an approved Fatigue Risk Management System covering governance, monitoring, training and auditing.

Who regulates it

Aviation in Canada is regulated federally, not provincially, by Transport Canada - a different body from the general workplace-safety regulators covering most other industries. Transport Canada has its own detailed rulebook specifically governing flight crew fatigue, duty time and rest periods, made under the Aeronautics Act.

Your obligations

Airlines must keep every flight crew member's duty time within Transport Canada's hard limits (roughly 9-13 hours, extendable with a larger crew) and give the required rest between duty periods - this is enforceable regulation with real numbers, not guidance. Operators must also track cumulative flight and duty time, not just single shifts. Wanting more flexibility than the fixed limits allow means building and getting approval for a full, audited fatigue-management program instead of just claiming to manage fatigue informally.

Consequences

Breaking the duty and rest limits is a Transport Canada matter first: inspectors can assess penalties without prosecution and, in serious or repeated cases, suspend or cancel the air operator certificate the business runs on. The same failure can be pursued separately under federal health and safety law, because an air operator is also a federally regulated employer. And a fatigue-related accident or incident brings in the Transportation Safety Board as an independent investigator, publishing its findings and any recommendations - a public record that outlasts the enforcement file.

Penalties

Transport Canada can assess penalties for breaching the flight and duty time rules at the amounts set in the Canadian Aviation Regulations - up to $5,000 per contravention for an individual and $25,000 for a corporation - and can suspend or cancel an air operator certificate. Since March 2026 the Aeronautics Act lets those amounts rise to $150,000 and $1,500,000. Canada Labor Code fines to $1,000,000 and penalties to $250,000 per violation also apply. 2026 figures.

Fatigue-critical roles

Where fatigue matters most in aviation

The roles where a fatigued worker is most likely to cause serious harm, the tasks that carry the risk, and why fatigue builds up in them.

Stories

When fatigue made the record

Published findings and prosecutions from regulators, courts and investigators in Canada.

Nov 2022 · Ontario, Canada
Captain with heavy sleep debt and 18 hours awake slips at 70 ft; passenger jet overruns runway
- Safety
A low-cost airline's narrow-body jet with 134 passengers overran the end of the runway at a regional airport at 6:25 am after the captain inadvertently pressed the go-around switch at about 70 feet, causing one engine to advance to near-maximum thrust during the landing roll. The Transportation Safety Board of Canada found the captain had built up a significant sleep debt over the previous week of night duties and had been awake for nearly 18 hours, at the end of the circadian low, and that this fatigue reduced his attention and made the slip more likely. The Board also found that when pilots do not monitor their own sleep debt, fatigue can go undetected and unmanaged.

Aug 2019 · Ontario, Canada
Captain with three fatigue risk factors on a backward-rotating roster; regional jet starts takeoff without clearance as a wide-body jet crosses the runway
- Safety
A regional jet began its take-off roll at a major airport without a take-off clearance while a wide-body airliner was crossing the runway; the crew aborted the takeoff when they saw the other aircraft over the crest of the runway. The Transportation Safety Board of Canada found the captain had three fatigue risk factors - acute sleep disruption, chronic sleep disruption and circadian rhythm disruption from moving from late evening to early morning shifts - and was experiencing some fatigue, but could not determine whether fatigue contributed. It found as a risk that backward-rotating shift schedules raise fatigue risk when crews lack time off to adapt.

Apr 2017 · Quebec, Canada
Survey pilots after almost 10 hours of low flying descend to 40 ft; mental fatigue a factor in fatal wire strike
- Safety
Two pilots flying a low-altitude aerial magnetometric survey struck a 69 kV power line after descending to between 100 and 40 feet on the way back, and both were killed. The crew had logged almost 10 hours of low-altitude flying in 12 hours that day. The TSB found that mental fatigue, sensation seeking and altered risk perception very likely contributed to the low flying.

Aug 2013 · Northwest Territories, Canada
Air taxi pilot with acute sleep debt on 13th flight of the day departs in a damaged aircraft; fatal crash
- Safety
An air taxi pilot flying 15 planned lodge-support flights in one day damaged the aircraft's wing on trees and then took off again without an inspection; the aircraft lost control and crashed into a lake, killing the pilot. The TSB found that cumulative unmanaged stressors disrupted the pilot's processing of safety-critical information, and its analysis named fatigue from an acute sleep debt among those stressors, alongside illness, workload, time pressure and frustration.

Jan 2012 · British Columbia, Canada
Sleepless captain presses on with unstable approach; passenger jet overruns runway
- Safety
A jet airliner on a charter flight carrying 112 workers from Alberta to a remote town in northern British Columbia ran 230 feet off the end of the runway after an unstable, long landing; no one was hurt. Investigators found the captain had little or no sleep in the previous 24 hours because his accommodation was noisy and hot, and that he had considered calling in sick but felt it would not be viewed favourably. Fatigue likely caused attention lapses and a fixation on salvaging the approach instead of going around.

Sleep inertia after controlled rest: first officer pitches airliner down, 16 hurt
- Safety
During an overnight transatlantic flight on a wide-body airliner operated by a Canadian airline, the first officer woke from a 75-minute controlled rest, misjudged an oncoming aircraft as a collision threat and pushed the nose down; 14 passengers and two flight attendants were injured. The Transportation Safety Board of Canada found sleep inertia, a circadian low and fatigue contributed, and that fatigue training had not conveyed the risks.

Feb 2010 · Ontario, Canada
Night-shift aircraft maintenance chief prone to falling asleep wins danger ruling against regional airline
- Safety
- Legal
A regional airline's maintenance crew chief on 12-hour night shifts (17:30 to 05:30) had a medical condition made worse by night work, with excessive sleepiness and persistent fatigue. His doctor recommended he be taken off nights, and he refused to work when he was put back on them. A health and safety officer found no danger, but the Occupational Health and Safety Tribunal Canada found that a danger existed, because he was prone to falling asleep while moving aircraft and heavy machinery on the apron and could reasonably have expected to be injured. The tribunal held that a worker's personal medical condition must be taken into account when deciding whether a danger exists.

May 2005 · Alberta, Canada
Regional airline captain on 3.5 hours' fitful sleep lets airspeed decay at 40,000 ft; stick shaker fires
- Safety
During cruise at 40,000 feet on a scheduled regional jet flight from Texas to Alberta with 64 passengers, the airspeed decayed below minimum drag speed while the crew worked on fuel calculations, and the stall warning stick shaker activated before the crew recovered by descending. The Transportation Safety Board of Canada found the captain was not well rested, having slept fitfully for only about 3.5 hours after arriving at his hotel at 3 am. It found fatigue likely degraded his concentration and drew his attention away from monitoring airspeed.

Oct 2004 · Nova Scotia, Canada
Cargo jet crashes on take-off; investigators find crew fatigue a factor
- Safety
A large freighter jet operated by a cargo airline crashed on take-off from an international airport in Nova Scotia after the crew used take-off performance data carried over from the previous airport; all seven crew died. The Transportation Safety Board of Canada found crew fatigue likely increased the probability of error in calculating the take-off data and degraded the crew's ability to detect it, and contributed to lost situational awareness on the take-off roll.

Jan 2004 · Ontario, Canada
Charter pilot on about 5 hours' sleep after cross-continent trip takes off iced and overweight; 10 killed
- Safety
- Financial
A single-engine turboprop on a charter flight took off from an island airstrip in freezing precipitation, about 15 percent over its maximum weight and with ice on the airframe, and struck the frozen surface of a lake, killing the pilot and all nine passengers. The Transportation Safety Board of Canada found the decision to take off was out of character for the pilot and was likely affected by stress and fatigue. The night before, he had returned from a trip to California across three time zones and could have slept at most 5 hours 15 minutes before reporting for duty at 4:45 am.

Aug 2001 · Ontario, Canada
Ferry pilot on duty over 20 hours after crossing six time zones crashes on night GPS approach
- Safety
A contract pilot ferrying a light single-engine aircraft across the Atlantic for an aircraft sales company crashed at about 2:20 am while attempting an improvised GPS approach to a northern regional airport in poor weather, and was killed. On the final day he had flown more than 1,900 nautical miles over about 19 hours, crossing six time zones, mostly single-pilot at night in cloud, after more than 20 hours on duty. The Transportation Safety Board of Canada found it likely that fatigue affected the pilot's performance and may have contributed to the accident.

Aug 1999 · Quebec, Canada
Commuter crew far over flight-time limits, first officer chronically fatigued; turboprop crashes on approach
- Safety
- Legal
A commuter turboprop on a scheduled night flight from an island community crashed one nautical mile short of the runway at a regional airport in fog, killing the captain and seriously injuring the first officer. The Transportation Safety Board of Canada found both pilots had exceeded their maximum monthly, quarterly and daily flight and duty times, and that the first officer had averaged 14-hour days for 30 days with one day off and had told the captain he was too tired and worn out. The national regulator was unaware of the exceedances and the company did not effectively supervise pilot duty times.

Aug 1997 · Quebec, Canada
Outfitter pilot on 3 hours' sleep a night overloads floatplane; strikes power lines, two staff killed
- Safety
A hunting-camp operator flying his own twin-engine floatplane to carry two camp cooks and supplies took off overloaded from a remote lake, could not climb and struck high-voltage lines; the aircraft burned and both employees died, while the pilot was seriously injured. The Transportation Safety Board of Canada found he had not allowed enough time to prepare his camps for the season and was fatigued, having slept only about three hours on each of the two nights before the flight. The Board noted fatigue increases risk-taking, and he chose not to abort a second, overweight take-off.

Jun 1994 · Manitoba, Canada
Medevac crew after long stand-by duty descend below approach altitude and hit beacon tower; 2 killed
- Safety
Just after midnight a twin turboprop returning from a medical evacuation flight descended below the mandatory altitude on approach to a northern regional airport, struck a navigation beacon tower and crashed, killing both pilots and seriously injuring the flight nurse. The Transportation Safety Board of Canada found the crew lost altitude awareness and listed probable pilot fatigue as a contributing factor. The first officer had been awake about 17 hours, had spent 180 hours on stand-by over the previous 14 days and had once been awake at least 36 hours straight in the days before.

About Awareness eLearning

Fatiguefit4Duty

Supports a named obligation

CARs 700.26(1) bars you from starting a crew member on a flight duty period once they advise they are too fatigued to be fit for duty. No method is named; Fatiguefit4Duty supports it. A fitness-for-duty check, not a fitness-for-duty decision - the duty call stays with you.

About Fatiguefit4Duty

Sleepfit

Supports your general duty of care

No Canadian aviation rule requires you to screen crew for sleep disorders; medical certification stays with Transport Canada. Sleepfit supports your general duty under s 124 of the Canada Labor Code. It screens; diagnosis stays with your clinicians.

About Sleepfit

Was It Fatigue?

Supports your general duty of care

Your incident investigation duties do not name fatigue unless you run a fatigue risk management system, where CARs Division V requires fatigue hazards to be identified from incidents. Was It Fatigue? supports that. A structured judgment aid, not a determination of cause.
