Darryl Sittler's no-trade clause protected him from being moved, when Toronto Maple Leafs owner Harold Ballard and manager Punch Imlach wanted to get rid of or reduce Sittler's influence on the team (Imlach instead traded Lanny McDonald to spite Sittler); a few years later Sittler waived the clause when relations between him and Ballard deteriorated. Dany Heatley demanded a trade from the Ottawa Senators at the end of the 2008–09 season; a deal was in place to send Heatley to the Edmonton Oilers on June 30, but Heatley refused to waive his no-trade clause (the Oilers had missed the playoffs for three straight seasons), so he was traded to the San Jose Sharks instead, with the Senators receiving a much lesser package than the one offered by the Oilers.[1] Rick Nash demanded a trade from the Columbus Blue Jackets during the 2011–12 NHL season, but the deal could not be completed due to general manager Scott Howson's high asking price from the teams to whom Nash would have permitted a trade.
