When Daylight Saving Time ends each fall, Canadians gain an extra hour of sleep. But for companies, the more significant impact is often reduced daylight, darker commutes, and changes to employee routines that can affect safety, alertness, and performance.
By Samantha Herriot, Occupational Wellness Manager at ABL
When Daylight Saving Time ends in the fall, employees generally adjust more easily than they do during the spring time change. However, darker mornings and evenings can create new workplace risks. Reduced visibility can affect commuting safety, outdoor work, vehicle operation, and employee alertness. Supervisors can reduce these risks by reviewing lighting, reinforcing safe driving practices, discussing fatigue awareness, and encouraging healthy sleep habits. According to the Canadian Centre for Occupational Health and Safety (CCOHS), changes in sleep schedules and daily routines can temporarily impact worker fatigue and concentration.
Fall Time Change & Workplace Safety: Key Canadian Statistics
At a Glance
- Pedestrian collisions increase by more than 30% during evening commute hours between November and March in Toronto, when daylight is reduced and visibility declines.
- More than 300 pedestrians die annually in Canada.
- 26% of pedestrian fatalities occur at night.
- Reduced visibility contributes to 23% of fatal pedestrian incidents in Canada.
- In 2023, 1,964 Canadians were killed and 26,503 were hospitalized with serious injuries resulting from road collisions.
These statistics demonstrate why employers should pay attention to the weeks immediately following the fall time change, especially when employees drive for work, travel between locations, work outdoors, or commute during peak traffic periods.
Why the Fall Time Change Matters to Employers
Although employees gain an hour of sleep when clocks move back, the transition still disrupts established routines and circadian rhythms. Circadian rhythms regulate sleep, alertness, mood, energy levels, and cognitive performance. Even small disruptions can affect concentration, decision-making, and reaction times. According to the Canadian Centre for Occupational Health and Safety (CCOHS), maintaining regular sleep schedules and healthy sleep habits can help workers manage these changes.
The effects may be more noticeable among:
- Shift workers
- Employees working extended hours
- Commercial drivers
- Outdoor workers
- Manufacturing and warehouse employees
- Workers operating machinery or vehicles
For supervisors, the goal is not to eliminate the effects of the time change but to proactively manage the risks that accompany it.
The Largest Risk: Reduced Daylight and Visibility
The most significant consequence of the autumn clock change is the abrupt reduction in daylight during commuting hours.
Workers who previously drove home in daylight may suddenly find themselves navigating rush-hour traffic in darkness. Employees arriving for early shifts may also encounter reduced visibility in parking lots, loading docks, and outdoor work areas.
According to data from the City of Toronto, pedestrian collisions increase by more than 30% during evening commute periods between November and March.
National statistics paint a similar picture. Statistics Canada reports that:
- More than 300 pedestrians are killed annually in Canada.
- More than one-quarter of pedestrian fatalities occur at night.
- Reduced visibility is identified as a contributing factor in nearly one-quarter of fatal pedestrian incidents.
For employers, these risks extend beyond the workplace itself. A safer employee commute contributes to overall workforce well-being, attendance, and productivity.
How Reduced Daylight Can Affect Workplace Performance
The fall time change may also affect how employees perform at work.
Some workers experience:
- Reduced concentration
- Slower reaction times
- Mild fatigue
- Decreased motivation
- Increased irritability
- Difficulty adapting to schedule changes
While these effects are typically temporary, even small declines in alertness can lead to errors, missed hazards, or reduced productivity in safety-sensitive environments. The Canadian Centre for Occupational Health and Safety (CCOHS) notes that fatigue remains an important workplace health and safety concern because it can affect judgment, coordination, and response times.
What Companies Should Do
- Remind Employees About the Time Change
A simple email, team huddle, toolbox talk, or internal newsletter reminder can encourage employees to prepare for the schedule adjustment and maintain healthy sleep habits.
- Conduct a Fatigue Awareness Discussion
Review common signs of fatigue with supervisors and frontline workers, including:
- Difficulty concentrating
- Slower reactions
- Increased mistakes
- Reduced situational awareness
- Drowsy driving
Encourage employees to communicate concerns before fatigue becomes a safety issue.
- Inspect Workplace Lighting
As daylight hours decrease, review:
- Parking lot lighting
- Building entrances
- Exterior pathways
- Loading docks
- Shipping and receiving areas
- Outdoor workspaces
Proper illumination can help reduce slips, trips, falls, and vehicle-related incidents.
- Reinforce Safe Driving Expectations
Transportation remains one of Canada’s leading causes of serious injury.
According to Parachute, transportation incidents are the second-leading cause of injury-related hospitalizations and the third-leading cause of unintentional injury deaths nationwide. In 2023 alone, road collisions resulted in 1,964 Canadian fatalities and 26,503 serious injuries requiring hospitalization.
Encourage employees to:
- Allow additional travel time
- Avoid distracted driving
- Clean vehicle lights and windows
- Watch carefully for pedestrians and cyclists
- Adjust driving habits to changing conditions
- Encourage Healthy Sleep Habits
Support employee well-being by encouraging workers to:
- Maintain consistent sleep schedules
- Limit screen time before bed
- Reduce caffeine late in the day
- Avoid excessive alcohol consumption
- Aim for at least seven hours of sleep per night
These practices can help workers adapt more smoothly to routine changes and maintain alertness throughout the workday.
Frequently Asked Questions
Does the fall time change increase workplace accidents?
Organizations such as the Canadian Centre for Occupational Health and Safety (CCOHS) and Energy Safety Canada recognize that fatigue, schedule disruptions, and reduced daylight can create workplace safety risks that employers should proactively manage.
Why are darker evenings a workplace concern?
Reduced daylight lowers visibility for drivers, pedestrians, cyclists, and outdoor workers. Canadian data show that nighttime and reduced visibility are contributing factors in a significant number of pedestrian fatalities.
Which employees are most affected by the fall time change?
Shift workers, commercial drivers, outdoor workers, field-service employees, warehouse associates, manufacturing workers, and anyone commuting during early morning or evening hours may be more affected due to changing visibility conditions and routine disruptions.
What is the most important thing a manager can do?
Review lighting, discuss fatigue awareness, reinforce safe driving practices, and communicate with employees before the time change occurs. Small preventative measures can significantly improve safety outcomes during the transition period.
Bottom Line for Supervisors
The greatest workplace impact of the fall time change is not the extra hour of sleep. It’s the reduction in daylight that follows.
By proactively addressing visibility concerns, monitoring fatigue risks, supporting healthy sleep habits, and reinforcing safe commuting practices, employers can help protect their workforce and maintain productivity throughout the darker months ahead.
