With the departure of its chief executive, Barbara Stymiest, TSX Group Inc. is on the hunt for a new boss.

The board of the TSX has established a search committee to find Stymiest’s replacement, and that search will begin immediately, the firm reports.

Stymiest leaves the exchange effective Oct. 31 to become chief operating officer at Royal Bank, amid a significant management shakeup there. She has led the TSX since September 1999, the result of a search that she led.

She led the exchange’s demutualization and its initial public offering, which has generally been viewed as a great success. The IPO was completed in November 2002.

In a news release, Wayne Fox, chair of TSX, said, “We wish Barbara every success in the next stage of her career and thank her for her leadership and contributions to the organization. Barbara leaves behind a strong management team that will continue to execute on the organization’s growth strategy as it has in the past.”

In its latest financial results, for the second quarter ended June 30, the company reported revenues were $74.3 million, up 41%. And, profit rose 54% to $24.9 million.
