Narrative:

We were cleared for takeoff from ont runway 26R, with instructions to turn left after takeoff, direct pdz, climb to 4000. We commenced the turn immediately after gear retraction, with flaps still extended 5 degree. Passing 2000 MSL and 180 degree heading, our TCASII gave a TA. The TA was at our 10-11 O'clock and 2-3 mi plus 200 ft. We visually acquired the target, a high wing, single engine, and determined we could not safely pass below him. We expedited our climb as the target turned to the right, passing directly underneath us. The TCASII showed minus 500 ft as we passed over him. Departure issued 'traffic 12 O'clock, less than a mi' as we were over the top of the traffic. Less than a mi indeed!
