Ballard remained as "de facto" general manager even when Imlach recovered. In September 1981, after Imlach had another heart attack during training camp, Ballard told the media that Imlach's poor health meant that "he's through as general manager". Imlach was never officially fired, but when he tried to return to his office in November, he found that his parking spot at Maple Leaf Gardens had been reassigned and Gerry McNamara had been made acting general manager. Imlach never returned to work and his contract was allowed to expire. Though Imlach was gone, Sittler's relationship with the Leafs worsened again in the 1981–82 season and he was traded that year to the Philadelphia Flyers.
