To fill its top finance job, TMX Group Ltd. is promoting from within.

The exchange operator said Monday in a news release that John McKenzie, who has been with TMX Group for 16 years and is an accountant by trade, has been named chief financial officer, effective July 11.

Since last July, Mr. McKenzie has been the president of Canadian Depository for Securities (CDS) Ltd., a subsidiary that clears equity and fixed-income trades in Canada. In addition to being CFO, he will continue to be president of CDS until his successor is named.

"John brings to the TMX Group CFO position a proven skill set and demonstrated leadership effectiveness," chief executive officer Lou Eccleston said in Monday's statement. "I am confident that this appointment will help propel the execution of TMX's strategy and enable us to continue along our stated path toward innovation, transformation and operational excellence."

Mr. McKenzie replaces former CFO Michael Ptasznik, who resigned this month to join Nasdaq Inc. in the same role. Mr. Ptasznick will also start his new job on July 11.
