Narrative:

We landed on runway 23 at toronto with the first officer the flying pilot. At about 50 KIAS we were transferring control from first officer to captain so that I could taxi off the runway. We were planning a normal rollout to taxiway H2. In the middle of transferring control; the tower called us and requested that we exit immediately on runway 15R. I believe that they said there was traffic on short final behind us. We looked to the left and saw much construction. There were two exits for the runway. The first was taxiway F; and the second exit was 15R. Both taxiway F and 15R were not blocked by cones (or anything else) for the construction. I was focusing on the construction and turned were I thought there were no workers. I saw what appeared to be an open exit from the runway; but evidently the workers were too close for us to be allowed to use taxiway F. The tower said; 'stop'. I believe that they told an aircraft to go around after that. The first officer read back that we were stopping. With the events happening very quickly; we were trying to verify our location. We noticed the sign for runway 15R a short distance to our right. We had accidentally exited the runway on taxiway F instead of runway 15R. We waited for several seconds. The tower then asked us to do a 180 and back taxi on taxiway F and make a right turn on taxiway J. We complied and had a normal taxi to the ramp after that. I called the tower on the telephone after arriving at the gate; and left a message twice (there was nobody answering the telephone on the number we have in our green sheets; only answering service). I left my cellular number; and requested that they call me to verify that they didn't need any more information. They never asked us to call them on the taxi in. I am not sure if canadian procedures require toronto tower to complete any paperwork or reports for the incident. They didn't ask any questions; and didn't appear that they wanted any more information. I talked to the chief pilot on duty; and we agreed that I should put in a report in case any more information was requested by toronto tower.I should not have reacted quickly to try and comply with ATC's instructions. With the confusing construction near the runway; I should have told ATC that we were continuing to our original exit point on the runway; taxiway H2. The other aircraft should have had enough separation from us to land after we taxied off the runway if we continued to taxiway H2. Also; if cones (or other devices) were in place; we would have known that workers were there; and would not have exited the runway at that location. It was unfortunate that we were given instructions at a high workload moment in the rollout; and we were unable to react quickly enough to correctly comply with there requests.
