Narrative:

I was captain on flight ord to yyz on 2/tue/91. Landed on runway 24R at yyz. Turned off at Q and was instructed to taxi via north, cross runway 33, right and hold short of taxiway F. At intersection of right and F was instructed by ground control to call apron advisory on 122.07. Cleared by apron advisory to taxi to gate clockwise (around terminal). Followed marked yellow centerline. Abeam gate 63, apron advisory instructed us to yield to outbnd. Mdt coming out from gate area 86 on the left. Taxied at slow speed and looked for the mdt. First officer and I were also looking and identifying gate #south on the right. Noticed a truck on the left side. Thought he was no factor and would keep out of the way. Taxied a bit to right of centerline, focusing my attention on the mdt and the aircraft parked on my right side. Abeam of gate 13 felt a bump and aircraft veered to the left. Stopped aircraft and set parking brake. Opened captain's sliding window and looked aft. Saw a sweeper truck under leading edge of left wing tip. Damage sustained to #1 slat and plexiglas housing of wing tip oscillating light. The area of the taxi incident was a controled taxi lane. The sweeper truck apparently had no radio contact with apron control. His maneuvering was restr by a concrete embankment because of a veh underpass. If a confined area is used for active taxiing, then vehicular traffic should be kept out or taxiing aircraft advised of activity.
