Bill Webb, executive vice president and chief investment officer of Toronto-based Gluskin Sheff + Associates Inc., will retire on Dec. 31, the firm announced on Wednesday.

“After 23 gratifying years in the investment industry, and a wonderfully rewarding 20 years with Gluskin Sheff, I have decided to dedicate my time and efforts to a number of community services and charitable interests of importance to me and my family,” Webb says in a statement. “This decision was made easier secure in the knowledge that our investment team is the deepest and strongest by far in the firm’s history.”

Peter Mann, managing director and head of equities, and Peter Zaltz, executive vice president and head of fixed-income, will become co-chief investment officers once Webb retires.

A transition of the portfolios Webb managed, which include some of the company’s institutional segregated accounts and the firm’s resources portfolio, is underway. Mann and Zaltz will continue to manage the firm’s U.S. equity and global credit portfolios.

“I am delighted to announce the appointment, effective Jan. 1, 2016, of Peter Mann and Peter Zaltz as co-chief investment officers of the company,” says Jeremy Freedman, president and CEO of Gluskin Sheff, in a statement. “I have been extremely impressed with the leadership each has shown of their respective areas and with the way they have collaborated to date to make our investment team and its processes stronger.”

This news follows the firm’s announcement in June that Jeffrey Burchell would join Gluskin Sheff as managing director and portfolio manager in August. Burchell resigned from his post as co-chief investment officer of Toronto-based Aston Hill Financial Inc. last month.
