Paul Godfrey is out as chairman of the Ontario Lottery and Gaming Corp. and he says the board has also resigned.
Finance Minister Charles Sousa says in a statement that he delivered the news to Godfrey at a meeting Thursday afternoon.
Sousa's statement gave no reason for Godfrey's dismissal.
Godfrey told a news conference he asked for a reason but wasn't given one and that Premier Kathleen Wynne told him the government was "going in a different direction."
Godfrey, who has held the job since February, 2010, speculated there just wasn't the proper chemistry between him and the premier.
The secretary of the cabinet, Peter Wallace, takes over as interim chairman.
