Toronto-based Mackenzie Investments said Wednesday that Mark Grammer, senior vice president, investment management, will become sole lead of the Mackenzie growth team at year’s end.

Ian Ainsworth, who has co-led the team with Grammer and dedicated 10 years of service to Mackenzie Investments, will be leaving the firm at the end of the year to pursue other interests.

“Ian has been a valued colleague and made a tremendous contribution to building our world-class capabilities in growth investing,” said Tony Elavia, chief investment officer, in a release. “We wish him well in his future endeavours.”

Ainsworth will work closely with his colleagues to ensure a smooth transition. Over the years, both he and Grammer have assembled a highly talented growth team, including portfolio managers Phil Taller and Chuck Bastyr, and analysts Klara Gotz, Natasha Dowding and John Lumbers.

Ainsworth will remain co-manager with Grammer of Mackenzie Growth Fund, Mackenzie Global Growth Class and Mackenzie US Growth Class and contributing manager to Mackenzie Canadian Concentrated Equity Fund until year’s end when Grammer will assume Ainsworth’s responsibilities. The funds will continue to be managed using the same investment strategy and processes currently employed.
