Incident Date: 2018-03-27
C-GHLV, a Boeing 767-300 aircraft operated by Air Canada rouge, was conducting flight ROU1981 from México City/Benito Juárez Intl, México (MMMX) to Toronto/Lester B. Pearson Intl, ON (CYYZ) with 8 crew members and 269 passengers on board. While holding short of Runway 05R on Taxiway A1 in preparation for the takeoff, the flight crew received their takeoff clearance. After the clearance was read back, the aircraft started to taxi to position. Shortly thereafter, a possible conflicting target on final for Runway 05R was identified on the TCAS. As the aircraft had partially crossed the hold short line, the flight crew stopped. ATC was queried and the tower controller advised ROU1981 to hold short of 05R. The conflicting aircraft on final was subsequently observed in the go-around.
