Narrative:

SID deviation lester 1 yyz. Frequency/altitude, yyz departure 3000 ft approximately. ATC facility: yyz departure. Location: lester 1 departure runway 24R yyz. We misunderstood yyz departure controller. Instead of staying on the SID we intercepted the 288 degree radial yyz on course. The controller caught it very quickly and said everything was ok, no problem. Now captain made phone call everything ok.
