Narrative:

Captain flying on an overcast, grey day, visibility greater than 7 SM. We were cleared by approach control for a visual approach to runway 27R as we passed 6000 ft on a left base, with advisories of a dash 8 on final to parallel runway 26. We were handed off to tower passing 4000 ft. We were once again advised about traffic landing on parallel runway 26 and were subsequently cleared to land on runway 27R. On short final at approximately 200 ft, we picked up another dash 8 on short final to runway 35, crossing runway approach end 27R. At our 11 O'clock position and 150 ft altitude. We executed a go around and crossed overhead the dash 8 approximately 100 ft. We were never advised of his position and were not aware of his proximity to us until seconds before execution of go around. Callback conversation with reporter revealed the following information: the reporter called the tower. The controller advised that a supervisor was not on duty and was not aware of the incident. The reporter stated that his concerns with the tower ensuring traffic separation were not resolved and during the conversation the controller made statements to the effect that these 'type events' were not uncommon.
