Narrative:

Yeg approach control handed us off to yeg tower. We were on an ILS runway 30 approach at yeg. I switched to tower and completed our landing checklist. Landing was uneventful and we taxied clear of runway and contacted ground who cleared us to gate. Later at the hotel, I received a phone call from who I believe was the yeg tower chief who informed me that we had landed without landing clearance. He also mentioned that there had been a service vehicle in the vicinity of the runway. He said it had been between 50 ft and 200 ft off the runway and that they had tried to inform us of this. He also asked if I would have accepted landing clearance with the knowledge that the vehicle was in the area. My response was that the runway was clear and that a vehicle 50 ft off the runway would not have impeded our landing. I cannot specifically recall asking for or receiving landing clearance, however, that is the normal operational procedure and I must have felt that we had received clearance. Workload in a 2 person cockpit, particularly during actual conditions, was a contributing factor in this incident.
