Stewart began his professional coaching career with the Muskegon Fury of the Colonial Hockey League in 1995. After one season with Muskegon, Stewart took the head coaching position with the Oshawa Generals of the OHL in 1996. Stewart got back into coaching professional hockey the following season with a stint in the American Hockey League and coaching the Saint John Flames to the Calder Cup Finals in 1998, losing to the Philadelphia Phantoms in six games. Stewart was named head coach of the New York Islanders on January 21, 1999 after Mike Milbury himself stepped down to concentrate solely on his GM duties. After finishing the season with the Islanders, Stewart was relieved of his coaching duties and was replaced by Butch Goring on April 30, 1999. In 1999, Stewart returned to the OHL to become the head coach of the Barrie Colts. The roster that year included the four "Brampton Boys", one of whom, Ryan Barnes, faced charges of assault with a weapon after a stick-swinging incident during a game in October. Later in the season, three of the team's other players were charged with sexual assault. Finally, Stewart himself made headlines and was banned from entering the United States for twice smuggling a Ukrainian-born player over the Canada-U.S. border in the baggage compartment of the team bus. Stewart infamously walked out of the Halifax Metro Centre without conducting any interviews to the media, following Barrie's 6-2 loss to the Rimouski Océanic in the 2000 Memorial Cupchampionship game. Following the controversial season in Barrie, Stewart continued his coaching career in Germany with and made headlines during the DEL quarterfinals in 2001 when he was involved in a mass brawl in game three against the Berlin Capitals, during which he hit Capitals' head coach Pavel Gross in the head and himself was injured as well. Stewart was handed a two-game suspension and a DM 15,000 fine. In the finals against the München Barons, he feigned fainting behind the Adler Mannheim bench to buy his star player Jan Alston time to get his skates sharpened. His team ended up winning the championship that year and got to the finals the following season. Stewart left Mannheim in January 2003 after being informed that his contract would not be extended at the end of the season. After a short stint in Krefeld, Stewart moved to Austria, where he coached the Graz 99ers and EHC Linz. He left Linz in December 2006 to return to Germany with the Hamburg Freezers. Linz challenged this transfer by seeking a restraining order, but lost the case. Stewart was sacked by the Freezers in December 2008. On December 3, 2009, he agreed to take over as the head coach of Kölner Haie and was relieved of his duties in November 2011. He joined the Guelph Storm during the 2011-12 season as a consultant prior to being named assistant coach in 2012-13. He took over as interim head coach of the team in January 2015. The term "interim" was then removed prior to the end of the season. He resigned from the Storm in December 2015 after only two wins and went back to Germany in January 2016 to coach Dresdner Eislöwen of the DEL2. Stewart was appointed head coach of the DEL's Straubing Tigers in April 2017. Concerning his past, he stated at that time: "I have experienced a lot in Europe, have had great success, but have to admit that I have gone too far at times. These moments happened some years ago and, in the meantime, I have learned and become more quiet." He was sacked as Straubing head coach on October 18, 2017 after his team won only eight of the first 13 games of the season and dropped to the very bottom of the DEL standings. On December 4, 2017, Stewart was named head of Adler Mannheim, returning for a second stint in charge at the club. His contract expired at the end of the 2017-18 season in which he guided the Adler team to an appearance in the playoff semifinals. He subsequently worked as a scout for the Adler organization.
