New Leafs general manager Kyle Dubas has two gaping holes to fill in the hockey department with the departures of senior advisor Lou Lamoriello and assistant GM Mark Hunter.

Lamoriello was announced Tuesday morning as the president of hockey operations for the New York Islanders, while Leafs president Brendan Shanahan issued a statement saying Hunter had left the organization.

“Following extensive discussions with Mark, he and the Toronto Maple Leafs have mutually agreed to part ways,” Shanahan said in a news release. “I’d like to sincerely thank Mark for everything he’s done for this organization over the last four years and I wish him nothing but the best in the future.”

Hunter, who built a reputation as a shrewd drafter and talent evaluator, had been passed over in favour of Kyle Dubas for the role of general manager.
