If you drive in Canada and follow the federal Hours of Service regulations, you can follow either a Cycle 1 or a Cycle 2 ruleset. Cycle 1 is 7 consecutive days, whereas cycle 2 is 14 consecutive days. If you elect to follow Cycle 1, you can accrue up to 70 hours of on-duty time (on duty driving and on duty not driving statuses) over the 7 day period. If you follow Cycle 2, you can accrue up to 120 hours on duty (on duty driving and on duty not driving statuses) over the 14 day period. Note that these hours requirements change when a driver travels north of latitude 60 degrees north.
