Hours of Service Rules in Canada (2026): Which Clock Stops You First?

November 03, 2026 — Fleet Safety Admin

Introduction

Most commercial drivers in Canada can recite the numbers: 13 hours of driving, 14 hours on duty, 10 hours off. Knowing the numbers is not the hard part. The hard part is knowing which limit applies to your trip, and which one runs out first.

Hours of Service Rules in Canada: The 2026 Limits at a Glance

Daily limits (south of 60°N)

• Driving time: 13 hours
• On-duty time: 14 hours
• Elapsed time: n/a
• Off-duty time: at least 10 hours

Work-shift limits (south of 60°N)

• Driving time: 13 hours
• On-duty time: 14 hours
• Elapsed time: 16 hours
• Off-duty time: shift resets after at least 8 consecutive hours

• 06:00–06:30 — Pre-trip inspection and paperwork 
  • Driving total: 0 h
  • On-duty total: 0.5 h
• 06:30–10:30 — Driving 
  • Driving total: 4 h
  • On-duty total: 4.5 h
• 10:30–12:00 — Loading 
  • Driving total: 4 h
  • On-duty total: 6 h
• 12:00–12:30 — Meal break (off duty) 
  • Driving total: 4 h
  • On-duty total: 6 h
• 12:30–16:30 — Driving 
  • Driving total: 8 h
  • On-duty total: 10 h
• 16:30–17:30 — Unloading 
  • Driving total: 8 h
  • On-duty total: 11 h
• 17:30–20:30 — Driving 
  • Driving total: 11 h
  • On-duty total: 14 h

At 20:30 the driver has driven only 11 hours. But they have reached 14 hours on duty, so they must stop driving. "I haven't driven 13 hours yet" is not the test.

Why Fleet Safety International Looks Beyond the 13-Hour Rule

Fleet Safety International has more than 40 years of experience in driver education and fleet safety. In that time, one pattern holds: drivers rarely get into HOS trouble because they forgot a number. They get into trouble because they tracked the wrong clock.

That is why we teach HOS as a sequence of decisions a driver makes throughout a shift, not a list of numbers to memorize.

Which Hours of Service Rules Apply to Your Trip?

You can't calculate your available hours until you know which rules govern the trip. Canada's federal Commercial Vehicle Drivers Hours of Service Regulations apply to federally regulated operations. Drivers working only within one province may fall under that province's HOS requirements instead.

• a truck, tractor, trailer or combination with a registered gross vehicle weight over 4,500 kg, or
• a bus designed to carry more than 10 people, including the driver.

Provincial HOS rules are not always identical to the federal rules. Don't assume one national set of numbers covers every trip.

Federal vs Provincial HOS Rules

Work through three questions before the trip:

1. Where does the carrier operate?
2. Does this trip cross a provincial, territorial or international boundary?
3. Which jurisdiction's rules govern this operation?

Alberta, for example, distinguishes between carriers operating only within Alberta and carriers operating across provincial, territorial or international borders. Ontario publishes its own HOS guidance in the Ministry of Transportation's truck handbook. If you drive only within one province, confirm that province's regulation rather than assuming the federal rules apply automatically.

Driving South vs North of Latitude 60°N

The federal regulation has a separate scheduling framework for driving north of 60°N, which includes Yukon, the Northwest Territories and Nunavut.

• Driving limit before 8 consecutive hours off 
  • South of 60°N: 13 hours
  • North of 60°N: 15 hours
• On-duty limit before 8 consecutive hours off 
  • South of 60°N: 14 hours
  • North of 60°N: 18 hours
• Elapsed-time limit in a work shift 
  • South of 60°N: 16 hours
  • North of 60°N: 20 hours
• Cycle 1 limit 
  • South of 60°N: 70 hours in 7 days
  • North of 60°N: 80 hours in 7 days
• Cycle 2 limit 
  • South of 60°N: 120 hours in 14 days
  • North of 60°N: 120 hours in 14 days

If your route crosses 60°N, know where the applicable scheduling rules change. A memorized "13-hour rule" will not carry you through a northern run.

The Three HOS Clocks Every Canadian Driver Needs to Track

Think of HOS compliance as three clocks running at the same time: your day, your work shift and your cycle. They measure different things and can run out at different times. Your legal driving window closes when the first one does.

Clock 1: Your 24-Hour Day

A day is a 24-hour period that begins at the hour your motor carrier designates, and that start time holds for the duration of your cycle. Within each day:

• No driving after 13 hours of driving time.
• No driving after 14 hours of on-duty time.
• At least 10 hours off duty.

Clock 2: Your Work Shift

The work-shift clock starts when a qualifying period of at least eight consecutive hours off duty ends. From that point, a driver may not drive after:

• 13 hours of driving,
• 14 hours on duty, or
• 16 hours of elapsed time.

Off-duty breaks taken during the shift stop on-duty time from building, but they do not stop the 16-hour elapsed clock. Only a new qualifying off-duty period resets it (the sleeper-berth provisions, covered below, are a separate case).

• 05:00–06:00 — Pre-trip and paperwork 
  • Driving total: 0 h
  • On-duty total: 1 h
  • Elapsed total: 1 h
• 06:00–10:00 — Driving 
  • Driving total: 4 h
  • On-duty total: 5 h
  • Elapsed total: 5 h
• 10:00–13:00 — Released off duty while the site is closed 
  • Driving total: 4 h
  • On-duty total: 5 h
  • Elapsed total: 8 h
• 13:00–14:00 — Loading 
  • Driving total: 4 h
  • On-duty total: 6 h
  • Elapsed total: 9 h
• 14:00–19:00 — Driving 
  • Driving total: 9 h
  • On-duty total: 11 h
  • Elapsed total: 14 h
• 19:00–19:30 — Meal break (off duty) 
  • Driving total: 9 h
  • On-duty total: 11 h
  • Elapsed total: 14.5 h
• 19:30–21:00 — Driving 
  • Driving total: 10.5 h
  • On-duty total: 12.5 h
  • Elapsed total: 16 h

At 21:00 the driver has 2.5 hours of driving and 1.5 hours of on-duty time left. It doesn't matter. Sixteen hours have elapsed, so driving must stop.

Clock 3: Cycle 1 and Cycle 2

The cycle clock tracks cumulative on-duty time across several days. The carrier chooses which cycle the driver follows.

• Cycle 1 
  • Limit (south of 60°N): No driving after 70 hours on duty in any 7-day period
  • Reset: At least 36 consecutive hours off duty
• Cycle 2 
  • Limit (south of 60°N): No driving after 120 hours on duty in 14 days, or after 70 hours on duty without first taking at least 24 consecutive hours off
  • Reset: At least 72 consecutive hours off duty

All drivers must also take at least 24 consecutive hours off duty in every 14-day period.You can't switch cycles just because you're running short of hours. Switching from Cycle 1 to Cycle 2 requires at least 36 consecutive hours off duty first. Switching from Cycle 2 to Cycle 1 requires at least 72.

How to Calculate Your Remaining Hours of Service Before Driving

Use the same four steps before dispatch and again whenever the plan changes. We'll follow one driver through all four: a federally regulated driver on Cycle 1, south of 60°N, whose day begins at midnight and whose eight-hour rest ends at 06:00. The shift follows the same schedule as the example at the top of this guide.

Step 1: Identify Your Ruleset and Cycle

• Confirm whether federal or provincial requirements apply.
• Confirm whether the trip is south or north of 60°N.
• Identify your cycle and add up the on-duty hours already accumulated in it.

Don't start with "How many hours can I drive today?" Start with how many cycle hours you have left.

Step 2: Establish the Day and Work-Shift Starting Points

• Identify the carrier-designated start of the 24-hour day.
• Identify when your latest qualifying eight-consecutive-hour off-duty period ended.

These two timestamps are often different, which is why the day and the work shift need separate calculations.

Step 3: Track Driving, On-Duty and Elapsed Time Separately

• Add driving time to both your driving and on-duty totals.
• Add non-driving work, such as inspections, loading and waiting while on duty, to on-duty time only.
• Keep counting elapsed time from the end of your qualifying off-duty period, including breaks.

Step 4: Compare All Remaining Clocks Before Continuing

Whichever clock has the least time left sets your real limit. Here is our driver's position at 06:00:

• Daily driving clock 
  • Limit: 13 h
  • Time available at 06:00: 13 h
• Daily on-duty clock 
  • Limit: 14 h
  • Time available at 06:00: 14 h
• Shift driving clock 
  • Limit: 13 h
  • Time available at 06:00: 13 h
• Shift on-duty clock 
  • Limit: 14 h
  • Time available at 06:00: 14 h
• Shift elapsed-time clock 
  • Limit: 16 h
  • Time available at 06:00: until 22:00
• Cycle 1 on-duty clock 
  • Limit: 70 h in 7 days
  • Time available at 06:00: 10 h

The cycle is the tightest clock, and every on-duty hour counts against it. By 16:30 the driver has completed a pre-trip, two driving legs and loading: 8 hours of driving and 10 hours on duty. That brings the cycle total to 70 hours.

Recheck this comparison after anything that changes the plan: delays, extra loading time, border waits or an unexpected change in duty status.

When Normal HOS Limits Can Change and When They Cannot

HOS flexibility provisions are conditional rules. They are not extra hours a driver can claim whenever a schedule gets tight. Each one comes with conditions to meet and records to keep.

Deferring Up to Two Hours of Off-Duty Time

An eligible driver may defer up to two hours of daily off-duty time to the following day. The deferred time cannot come from the mandatory eight consecutive hours. The deferral is only valid if:

• total off-duty time across the two days is at least 20 hours,
• total driving time across the two days does not exceed 26 hours, and
• the record of duty status clearly declares which day is Day 1 and which is Day 2.

Deferral moves rest from one day to the next. It does not give you a way around the normal work-shift limits.

Splitting Off-Duty Time in a Sleeper Berth

A single driver using a qualifying sleeper berth can split off-duty time into no more than two periods. Neither period can be shorter than two hours, and together they must total at least 10 hours. Driving, on-duty and elapsed-time conditions still apply before and after each period. Team drivers follow a separate set of requirements, so don't apply the single-driver formula to a team operation.

• Split: 8 h + 2 h 
  • Legal?: Yes
  • Why: Two periods, each at least 2 h, totalling 10 h
• Split: 9 h + 1.5 h 
  • Legal?: No
  • Why: One period is shorter than 2 h
• Split: 7 h + 2 h 
  • Legal?: No
  • Why: Total is only 9 h
• Split: 4 h + 3 h + 3 h 
  • Legal?: No
  • Why: More than two periods

Adverse Driving Conditions and Emergencies

Adverse driving conditions are snow, sleet, fog or other adverse weather or road conditions that were not known, and could not reasonably have been known, before the driver started driving. South of 60°N, a driver who meets the stated conditions may take up to two additional hours to complete the trip. The driver must still take the required eight consecutive hours off duty, and the trip must have been possible to complete under normal conditions.

Personal Use of a Commercial Vehicle

Federal rules allow limited personal use of a commercial vehicle without counting it as on-duty time, but only when every condition is met:

• the vehicle travels no more than 75 km in the day,
• it has been unloaded and any trailers unhitched,
• it is not being used for the carrier's business, and
• the odometer readings at the start and end of personal use are recorded.

Calling a trip "personal conveyance" doesn't make it so. Driving an empty, unhitched tractor 20 km from the yard to a restaurant and back can qualify. Moving that tractor 20 km to stage it closer to tomorrow's pickup benefits the carrier, so it is on-duty driving.

ELDs, Records of Duty Status and the Compliance Errors Drivers Should Catch

An electronic logging device (ELD) records duty status. It does not decide which limits or exceptions apply to your trip. That responsibility stays with the driver and the carrier.Federally regulated commercial vehicles generally must use a certified ELD that meets the applicable technical standard. The federal exceptions include:

• operations within a 160 km radius of the home terminal (conditions below),
• vehicles manufactured before model year 2000,
• rentals of 30 days or less that are not extended or renewed, and
• vehicles operated under a permit or an exemption issued under the Act.

An ELD exemption is not an HOS exemption. A driver who doesn't need an ELD still has to follow every driving, on-duty, off-duty and cycle limit.

• Confusing a 24-hour day with a work shift.
• Watching driving time while ignoring non-driving on-duty work.
• Continuing to drive because the 13-hour clock is open after another limit has expired.
• Resetting or switching between Cycle 1 and Cycle 2 without the required off-duty hours.
• Treating off-duty deferral as extra, unrestricted driving time.
• Claiming adverse driving conditions for weather or traffic that was reasonably foreseeable.
• Assuming an ELD exemption removes the underlying HOS obligations.
• Logging movement that benefits the carrier as personal use.

Build HOS Decisions Into Every Shift

The numbers matter, but compliance comes from tracking every clock, every shift. For carriers and safety managers, hours of service is also a core part of National Safety Code (NSC) compliance. Fleet Safety International's three-hour Canadian Federal Hours of Service Online Training walks carriers, shippers and drivers through daily logs, work shifts, cycles, exemptions, electronic recording devices, adverse driving conditions and out-of-service rules. Learners finish with a certificate and digital badge.
