🇨🇦 Canadian HOS Cycle Planning Calculator

A user-input, arithmetic-only hours-of-service planner. Pick your region and cycle, enter the on-duty hours you have already used, and see your estimated cycle hours remaining beside the source-backed reference limits from SOR/2005-313. This tool does not determine compliance with any law.

🍁 Your Cycle (hours)
Reference limits differ north vs south of 60°N. You select your region — the tool does not detect it.
Choose the cycle you are following. The tool does not decide which cycle applies to you.
Total on-duty hours you have already accumulated in the current cycle window.
Used only to subtract from the daily driving reference figure.
Used only to subtract from the daily on-duty reference figure.
All figures are arithmetic on what you enter. Nothing here is a determination of legal status.

Reference limits from the Commercial Vehicle Drivers Hours of Service Regulations (SOR/2005-313), current to 2026-05-26, last amended 2021-06-12. Section references are shown with each figure once you calculate.
Not legal or compliance advice. This tool does arithmetic on the hours you enter and does not determine compliance with any law. Limits differ by jurisdiction, carrier type, exemptions, operating region, and current regulatory updates. Federal SOR/2005-313 applies to extra-provincial carriers; provincial rules may apply to intra-provincial carriers. Confirm which rules apply to you, and the current figures, with the official regulation and your regulator before operating. Reference limits shown are from SOR/2005-313, current to 2026-05-26.

Plan your cycle hours before you roll

Canadian commercial-driver hours of service are tracked in cycles: on-duty time accumulates over a 7-day window (Cycle 1) or a 14-day window (Cycle 2). This planner is a simple arithmetic helper — you tell it your region and cycle and how many on-duty hours you have already used, and it subtracts that from the cycle's reference on-duty limit so you can see roughly how many hours you have left to plan around. It is not a log, an ELD, or a compliance check, and it does not decide which rules apply to you.

Every reference figure below is drawn from the federal Commercial Vehicle Drivers Hours of Service Regulations (SOR/2005-313) and is shown with its section number so you can verify it against the official text. The limits differ depending on whether you operate south or north of latitude 60°N, which is why you choose your region rather than the tool guessing it.

Cycle 2 note: Cycle 2 carries additional conditions in the regulation beyond the flat 120-hour figure shown here. This tool deliberately shows Cycle 2 as a flat reference limit only and does not encode those further conditions — review the official regulation (s. 27 south, s. 52 north) for the full requirements that apply to you.

Frequently Asked Questions

What does this HOS cycle planning calculator do?
It does arithmetic on the hours you enter. You select your operating region (north or south of latitude 60°N) and whether you are following Cycle 1 or Cycle 2, then enter the on-duty hours you have already used in the cycle. The tool subtracts that from the cycle's reference on-duty limit and shows the estimated hours remaining, alongside source-backed daily driving, on-duty, off-duty, reset, and switching reference figures. It does not determine whether you are compliant with any law.
Where do the reference limits come from?
From the federal Commercial Vehicle Drivers Hours of Service Regulations (SOR/2005-313), made under the Motor Vehicle Transport Act, current to 2026-05-26 and last amended on 2021-06-12. South of latitude 60°N: Cycle 1 is 70 hours of on-duty time in any 7 days (s. 26) and Cycle 2 is 120 hours in any 14 days (s. 27); daily references are 13 hours driving (s. 12(1)), 14 hours on-duty (s. 12(2)), and 10 hours off-duty (s. 14(1)). North of latitude 60°N: Cycle 1 is 80 hours in any 7 days (s. 51) and Cycle 2 is 120 hours in any 14 days (s. 52(a)); daily references are 15 hours driving and 18 hours on-duty (s. 39(1)). Cycle reset is 36 hours for Cycle 1 and 72 hours for Cycle 2 (s. 28(1) south, s. 53(1) north); switching is 36 hours for 1 to 2 and 72 hours for 2 to 1 (s. 29(1) south, s. 54(1) north).
Does the tool tell me if I am legal or compliant?
No. It performs arithmetic on the figures you enter and shows reference limits drawn from the regulation. It does not determine legal status, compliance, or which set of rules applies to you. Hours-of-service rules differ by jurisdiction (federal SOR/2005-313 applies to extra-provincial carriers; provincial rules may apply to intra-provincial carriers), by carrier type, by exemptions, and by operating region. Confirm which rules apply to you, and the current figures, with the official regulation and your regulator before operating.
Why is Cycle 2 shown as a flat 120-hour limit?
Cycle 2 carries additional conditions in the regulation beyond the 120-hour figure. This tool intentionally shows only the flat 120-hours-in-14-days reference and does not encode those further conditions. If you follow Cycle 2, review the official regulation (s. 27 south, s. 52 north) for the full requirements that apply to you.
Does this calculator cover provincial hours-of-service rules?
No. It uses only the federal Commercial Vehicle Drivers Hours of Service Regulations (SOR/2005-313). It does not encode provincial rules, sleeper-berth or split-sleeper provisions, off-duty deferral, exemptions, permits, emergency provisions, or enforcement and penalty rules. Drivers governed by provincial rules, or relying on any of those provisions, must consult the rules that apply to them.
