Citing tensions between TDSB education director Donna Quan and the school board itself, Irene Atkinson said Premier Kathleen Wynne and Education Minister Liz Sandals should meet with the board chair about the matter.
In her letter to Wynne and Sandals, Atkinson describes a "rift" between Quan, her staff and the board that "appears insurmountable without an arm's length independent investigation, and conclusions reported to you for whatever action you deem appropriate."
When speaking with CBC Radio's Metro Morning on Tuesday, Atkinson was asked to explain her personal concerns about Quan.
"She seems to conduct herself as if she is both the director and the board," said Atkinson.
"And she seems to ignore the board or chastise the board and that is not her role."
Among the complaints from trustees is an allegation that Quan has refused to show them her employment contract.
"The fact of the matter is there is a performance review for the director and you can’t very well do a performance review if you don’t have a copy of the contract," she said.
Quan has yet to comment. She did not immediately respond to a request for comment from CBC News.
