"One of my goals every offseason is to put together the best staff possible to help give us the greatest opportunity for team success," said Sheldon Keefe. "With Spencer Carbery's departure to become the head coach of the Washington Capitals, I'm thrilled to add experienced and accomplished coaches like Guy and Mike, as well as how the roles and responsibilities will now be shared amongst our coaching staff moving forward."
Boucher, 51, previously served as head coach of the Tampa Bay Lightning (2010-11 to 2012-13) and the Ottawa Senators (2016-17 to 2018-19), posting a combined record of 191-186-46. Under Boucher's guidance, the Lightning reached the Eastern Conference Final in 2011 while the Senators made the Eastern Conference Final in 2017. Prior to joining the Senators, Boucher spent three seasons in Switzerland (2013-14 to 2015-16) where he served as head coach of Bern SC (Swiss-A). The club posted a 44-29-5 record during his tenure.
Boucher was previously a coach in the AHL, the QMJHL and in the Swiss League. He coached a rival to Auston Matthews' ZSC Lions in the year he was over there.
Van Ryn, 44, joins the Maple Leafs staff after spending the previous five seasons (2018-19 to 2022-23) as an assistant coach with the St. Louis Blues. Van Ryn helped the Blues capture a Stanley Cup in 2019.
Prior to joining the Blues, the London, Ontario native spent two seasons with the Arizona Coyotes organization, including one year as head coach of the club's AHL affiliate, the Tucson Roadrunners, in 2017-18. Van Ryn led the Roadrunners to a 42-20-5 record and first place in the Pacific Division.
Van Ryn also coached in the OHL and AHL in the past.
As the news release makes clear all the other coaching staff are retained: including assistants Dean Chynoweth and Manny Malhotra, goaltending coach Curtis Sanford, and video coaches Jordan Bean and Sam Kim.
