2104 Toronto, provisional designation 1963 PD, is a metallic background asteroid from the outer regions of the asteroid belt, approximately 36 kilometers in diameter. It was discovered on 15 August 1963, by Karl Kamper at the David Dunlap Observatory on plates taken by Sidney van den Bergh at the Karl Schwarzschild Observatory in Tautenburg, Germany. The asteroid was named after the University of Toronto. It was the first asteroid discovered at an observatory in Canada.[2][11]
