TMX Group, Canada's flagship exchange operator, on Monday said it named Lou Eccleston as its new chief executive, ending a months-long search for a successor to the retiring Tom Kloet.

Eccleston, 57, will assume the top job on November 3, bringing with him more than 30 years of experience in the financial technology and capital markets sectors, according to TMX. Most recently, Eccleston was president of financial data provider S&P Capital IQ, a provider of earnings estimates and other financial data for publicly traded companies. He was also chair of S&P Dow Jones Indices, a joint venture between McGraw Hill, the controlling shareholder, and CME Group.
