A Jazz Canadair CRJ-705, registration C-GNJZ performing flight QK-8619 from Toronto,ON (Canada) to Atlanta,GA (USA), was climbing out of Toronto's runway 06L having been cleared for a Lester 8 standard instrument departure, which required the aircraft to climb to 5000 feet on a heading of 067 degrees.

About the same time a Westjet Boeing 737-700, registration C-FWBL performing flight WS-659 from Toronto,ON to Winnipeg,MB (Canada), departed Toronto's runway 05 and was in the initial climb already handed off to departure, when the CRJ-705 made a turn to the left without clearance causing the separation between the two aircraft to be lost. Tower instructed the Canadair crew to stop the climb at 2000 feet, in the first attempt calling Jazz 691 and repeating with correct callsign Jazz 619 (QK-8619) in the second attempt, and after the crew acknowledged handed the aircraft off to departure.

The Canadian TSB reported the horizontal separation between the two aircraft reduced to approximately 1nm without stating remaining vertical separation, however confirming required separation between the aircraft was lost. The CRJ was instructed to stop the climb at 2000 feet and turn right to resolve the conflict.

Both aircraft continued to their destinations for safe landings.
