Narrative:
On may/sun/01, I operated flight abcd, scheduled service from toronto to pittsburgh. 1 flight was cleared as per our flight plan via the lester 4 SID. Tower controller cleared us for takeoff on a heading of 100 degrees. PNF read back takeoff clearance with a turn to 100 degrees on departure. Takeoff was normal. At approximately 400 ft AGL, the PF started a right turn from 057 degrees to 100 degrees. At a heading of 80 degrees the tower controller asked us our heading. The PNF replied 'turning to a heading of 100 degrees as assigned.' the tower controller informed us that the 100 degree heading was not for our flight, and issued us a left turn back to 060 degrees. The PF complied with a turn (left) to 060 degrees. At 3000 ft AGL our flight was switched over to toronto departure and proceeded without further action. We felt that the heading of 100 degrees on departure was an authority/authorized by ATC and issued for our flight. We believed that no correction on our readback from the tower controller was our verification that our readback was correct.

Title: HDG TRACK DEV WHEN DEP DC9 FLT CREW COPIES HDG ISSUED TO ANOTHER FLT AT CYYZ.
Narrative: ON MAY/SUN/01, I OPERATED FLT ABCD, SCHEDULED SVC FROM TORONTO TO PITTSBURGH. 1 FLT WAS CLRED AS PER OUR FLT PLAN VIA THE LESTER 4 SID. TWR CTLR CLRED US FOR TKOF ON A HDG OF 100 DEGS. PNF READ BACK TKOF CLRNC WITH A TURN TO 100 DEGS ON DEP. TKOF WAS NORMAL. AT APPROX 400 FT AGL, THE PF STARTED A R TURN FROM 057 DEGS TO 100 DEGS. AT A HDG OF 80 DEGS THE TWR CTLR ASKED US OUR HDG. THE PNF REPLIED 'TURNING TO A HDG OF 100 DEGS AS ASSIGNED.' THE TWR CTLR INFORMED US THAT THE 100 DEG HDG WAS NOT FOR OUR FLT, AND ISSUED US A L TURN BACK TO 060 DEGS. THE PF COMPLIED WITH A TURN (L) TO 060 DEGS. AT 3000 FT AGL OUR FLT WAS SWITCHED OVER TO TORONTO DEP AND PROCEEDED WITHOUT FURTHER ACTION. WE FELT THAT THE HDG OF 100 DEGS ON DEP WAS AN AUTH BY ATC AND ISSUED FOR OUR FLT. WE BELIEVED THAT NO CORRECTION ON OUR READBACK FROM THE TWR CTLR WAS OUR VERIFICATION THAT OUR READBACK WAS CORRECT.
