The 2018 changes

This site focuses on the rules as they are now. This page is the short history of how they got here.

What happened

After roughly a decade of work to bring Canada’s pilot duty and rest rules in line with modern fatigue science, the final rule was published on 12 December 2018 in the Canada Gazette, Part II, as SOR/2018-269. It amended the Canadian Aviation Regulations (SOR/96-433).

The old regime was built mainly on flight-time limits plus a fixed maximum duty day (14 hours, extendable to 17 with rest). The new regime replaces that with:

  • science-based flight-duty-period tables (700.28) keyed to the time of day the duty starts, the number of flights, and their average length;
  • explicit ceilings on hours of work (700.29);
  • rules for disruptive schedules (700.41), time-zone rest (700.42), reserve and standby (700.70700.71), controlled rest on the flight deck (700.72), and a Fatigue Risk Management System route for operators that can show a schedule is not fatiguing;
  • a shift from bottle-to-throttle 8 hours to 12 hours for alcohol (CARs 602.03).

The old-versus-new detail

The previous version of this site walked through the changes section by section, with the old and new text side by side. That material is being folded into the individual rule pages as a “What changed in 2018” expander, rather than kept as a separate archive. For the authoritative before/after, the amending instrument is SOR/2018-269 in the Canada Gazette, and the pre-amendment text is available as a dated version on the Justice Laws website.
