Canadian rules for US drivers

A US driver who crosses into Canada is on Canadian hours of service rules from the moment of crossing, with every hour worked in the States counted. Canada allows 13 hours of driving in a shift and 13 in a day, 14 on duty, and no driving after 16 hours from the start of the shift.

On a cross-border run this means

Going north, the trap is the day. A driver can take a full rest in the States, start a fresh shift, and still be close to Canada's 13 hours for the day because of driving done earlier the same day.

A northbound run after a full rest, for a driver who already drove earlier the same day.

The run
Leaves at 15:00, drives 30 m to the border, then 8 h 30 m after it

This is the answer the free check gives for these hours.

NO-GO

Not legal as planned. The run breaks the Canadian 13-hour driving limit.

Why

Binding limit: Canadian 13-hour driving limit (SOR/2005-313 s. 12(1)). This is the daily limit. The carrier's day starts at 00:00. Hours worked on both sides of the border count toward it.

Read how this limit works

What makes this a GO

1 h off duty from 15:00, then depart at 16:00 EDT on Mon Oct 5 or later. The rest of the run stays the same.

Where the hours came from

Hours entered by hand.

BorderHOS is a planning aid. It does not replace your ELD, the driver's judgment, or the regulations. Results depend on the hours used.

How this was worked out
  1. Hours read at 15:00 on Mon Oct 5: 0 m driving and 0 m on duty this shift. Hours count under both countries' rules; only the rules change at the border.
  2. Earlier today, before the rest that started this shift: 5 h driving and 5 h on duty. Canada counts them toward the day's 13 hours of driving and 14 hours on duty.
  3. Departs 15:00, drives 30 m in the US, crosses at 15:30, then 8 h 30 m in Canada.
  4. At the border under Canadian rules: 7 h 30 m of driving left, 8 h 30 m of on-duty time left, 15 h 30 m of the 16-hour window left, 29 h 30 m of Cycle 1 left.
  5. First limit broken: the Canadian 13-hour driving limit at 23:00, in Canada.
  6. Earliest legal departure, resting off duty from 15:00: 16:00 on Mon Oct 5.
What this check does not cover
  • Sleeper-berth splits are not modeled.
  • Canadian deferral of daily off-duty time is not modeled.
  • Adverse driving conditions are not modeled.
  • Team drivers, north of 60, oil-well permits and short-haul exemptions are not modeled.
  • Border wait is not added. Time waiting in line counts as on duty.
  • The date of the driver's last 24 hours off was not given. It is assumed to fall within the last 14 days for the whole run.
  • Canada requires records of duty status for the current day and the preceding 14 days on board. Confirm before crossing.

Questions

Does a 34-hour restart count in Canada?

Not as a Canadian reset. Cycle 1 starts over after 36 hours off in a row and Cycle 2 after 72. A driver who needs a reset in Canada needs the full Canadian one.

Do US drivers need 24 hours off in 14 days to drive in Canada?

Yes. No driving in Canada unless the driver has taken at least 24 hours off in a row in the last 14 days, however many cycle hours are left.

Can a US driver drive 13 hours in Canada?

Up to 13 in a shift and 13 in a day, counting the hours driven in the States. A driver who drove 11 in the US that day has only what is left of the 13.

When the check says NO-GO

  • Canadian vs US hours of service, every difference

    Every difference between Canadian federal and US FMCSA hours of service, side by side, cited to the regulation. Verified and dated.

  • Cycle 1 vs Cycle 2

    70 hours in 7 days or 120 in 14. What each Canadian cycle allows, the second Cycle 2 limit, and the 36 and 72-hour resets.

  • 13 hours vs 11 hours

    Canada allows 13 hours of driving a day, the US 11 after 10 off, and the hours carry across. What is left at the border, with a worked run.
