"As you know, I have been an ardent supporter of TFC since you and MLSE first had the vision to bring Major League Soccer to Toronto," Miller said in his letter to Maple Leaf Sports & Entertainment posted on Facebook. "I have supported the team through thick and thin, defended management, was one of the first season ticket holders, and, in my former capacity, was instrumental in building the stadium and supporting its conversion to grass.
"I am so frustrated with the latest management missteps that I am returning the remainder of my season tickets to you: it is the only way I can emphasize how serious the situation is for those of us who support TFC. Please donate them to an appropriate cause."
Miller's ire at the 4-13-10 franchise, which looks set to miss the playoffs for the seventh straight year, came in the wake of the club's decision to fire president and GM Kevin Payne and trade newly acquired Argentine striker Maximiliano Urruti.
"There once was magic at BMO Field. The latest reshuffle has made the possibility of that magic returning almost certainly disappear," Miller wrote.
The former mayor also seemed irked that the ownership was looking at possibly retrofitting BMO Field to accommodate CFL football.
In returning his tickets, Miller will be forgoing four home games.
