Published: 2026-09-17
Effective: 2026-09-11
Affected Location: Toronto/Lester B. Pearson International Airport (CYYZ)
Type: Safety Advisory
FIR: CZYZ (Toronto FIR)
π§ What Changed (Summary)
Runway holding position stop bars providing runway entry protection at CYYZ will operate continuously (24/7). Stop bars will remain illuminated unless extinguished by ATC to permit an authorized movement.
- Effective 11 Sep 2026 at 0400 UTC, all runway entry protection stop bars at CYYZ operate 24 hours/day, 7 days/week.
- An ATC clearance/instruction alone does not authorize crossing an illuminated stop bar.
- Proceed beyond the runway holding position only when both: (1) appropriate ATC clearance/instruction has been received, and (2) the stop bar has been extinguished.
- If cleared/instructed but the stop bar remains illuminated, stop and obtain clarification from ATC before proceeding.
- No changes to published ATC phraseology are associated with this implementation.
βοΈ General Aviation Impact (Highlighted)
Operational Notes:
- Expect stop bars to be illuminated at all times at CYYZ unless ATC extinguishes them for your authorized movement.
- Do not cross an illuminated stop bar even if you have a clearance; stop and query ATC if there is any conflict between the clearance and stop bar status.
VFR Impact:
- VFR aircraft and airside vehicle operators at CYYZ should anticipate continuous stop bar illumination and comply with the requirement to stop at illuminated stop bars until extinguished by ATC.
