Narrative:

Air carrier X cleared for a visual approach to runway 15 at burlington, vt, airport. We turned final at approximately 7 mi from the runway following the localizer and GS and were cleared to land on runway 15. The tower told us they would depart 2 fgt's prior to our arrival. At approximately 3-4 mi from the end of the runway (15) we got a TA followed shortly thereafter by an RA and then a command to climb, climb. There was an small aircraft Y single engine aircraft on the localizer at approximately 800-900 ft. We missed the aircraft Y by less than 1/2 mi and 100 ft altitude. We started a climb when commanded and I called the tower and told them I was going around. When I advised the tower I was going around they told me they had an aircraft northbound off runway 19 or there was someone over the numbers. The tower then told us to fly a heading of 330 degrees for vectors back to runway 15.
