The Canadian Triple Crown had not been won since Canebora in 1963. To raise interest in the series, the Bank of Montreal introduced a $1 million bonus in 1989 to any horse who could sweep the three races. Attfield was optimistic about With Approval's chances, feeling that the colt would improve when switching from the dirt surface on which he had won the first two legs of the Crown to the turf course over which the final race, the Breeders' Stakes, is run. With Approval had run on turf once before, in his first race, and had won by two lengths. "He's been training super," said Attfield. "He's in unbelievably good shape. He couldn't be better." With Approval rewarded Attfield's confidence with a seven-and-a-half-length victory in the Breeders' Stakes.
