An American Airlines Boeing 737-800, registration N976NN performing flight AA-2172 from Charlotte,NC to Sarasota,FL (USA), was on a visual final approach to runway 14 and was cleared to land on runway 14.
About 3 minutes later an Air Canada Airbus A321-200, registration C-FJQH performing flight AC-1633 from Sarasota,FL (USA) to Toronto,ON (Canada), reported ready for the departure and was cleared for takeoff, however, it appears that transmission of the takeoff clearance was stepped on by another aircraft. The crew queried tower about 30 seconds later whether they had understood correctly they were cleared for takeoff, tower affirmed, the crew thus proceeded for takeoff.
The crew of the American B738 advised about another minute later they were going around initiating a go around from very low height (about 150 feet AGL) about 0.3nm before the (displaced) runway threshold and began to immediately turn right onto downwind. The aircraft climbed to 3000 feet, positioned for another approach and landed safely on runway 14 about 8 minutes later.
The Air Canada Airbus continued takeoff, climbed out and continued to Toronto for a safe landing without further incident."
