Prior to the launch of the Ottawa Nationals of the World Hockey Association (WHA), the team had discussions with Ballard about locating the team in Toronto, but the talks did not get very far. The team was a flop at the box office, averaging about 3,000 fans a game, and in March 1973—just before the end of the season—the City of Ottawa demanded payment of $100,000 to guarantee the club dates at the Ottawa Civic Centre. The team decided to leave Ottawa and played their home playoff games at Maple Leaf Gardens, attracting crowds of 5,000 and 4,000 in two games before being eliminated by the New England Whalers. At the end of the season, the team moved to Toronto permanently, and was sold to John F. Bassett, son of former Leafs owner John Bassett. They were renamed the Toronto Toros in June 1973. Bassett wanted the team to play at a renovated CNE Coliseum, while Bill Ballard—Harold's son, who was running the Gardens while his father served a prison sentence—wanted the team at the Gardens and opposed the plan to upgrade the Coliseum. The Toros ended up at Varsity Arena for the 1973–74 season. The following season, the Toros moved to the Gardens after negotiating a lease with Bill. However, by the time the team played their first game at the Gardens, Harold had been released from prison and regained control of the company. Ballard was a virulent opponent of the WHA; he never forgave the upstart league for decimating the Leafs' roster in the early 1970s. He made the Toros' lease terms at the Gardens as onerous as possible. The Toros' lease called for them to pay $15,000 per game. However, much to Bassett's outrage, the arena was dim for their first game. It was then that Ballard demanded $3,500 for use of the lights. Ballard also denied the Toros access to the Leafs' locker room, forcing them to build their own at a cost of $55,000. He also removed the cushions from the home bench for Toros' games. Following two seasons of declining attendance and onerous lease terms at the Gardens, Bassett moved the club to Birmingham, Alabama, where they were renamed the Birmingham Bulls for the 1976–77 season.
