Canadian HOS (Hours of Service) rules are different from the U.S. rules. In Canada, when speaking of how long you can drive, the rules speak of “per day” and “work shift”. Per day refers to a calendar day (midnight to midnight). A work shift refers to the time between two periods of rest of at least 8 consecutive hours. You need to always be compliant with both.
Daily Driving Rule
In addition to Canadian Daily Driving Rules,
Canada required drivers to choose between two Cycles:
You must declare which cycle you are using every day in your logbook.
Cycle 1 - 70 hours in 7-days or
Cycle 2 - 120 hours in 14-day
When using Cycle 1, you cannot log more than 70 hours On-Duty (Driving & On-Duty Not Driving) in 7 days.
When using Cycle 2, you cannot log more than 120 hours On-Duty (Driving & On-Duty Not Driving) in 14 days. Also, when using Cycle 2, you cannot not drive after accumulating 70 hours on-duty without taking a period of 24 consecutive hours off-duty.
In both Cycle 1 and Cycle 2: you must have a period of at least 24 consecutive hours off-duty in the preceding 14 days.
