• OHL MVP (1983) Frank J. Selke Trophy (1993)
• Played in NHL All-Star Game (1993, 1994)

When Doug Gilmour made the move to the Cornwall Royals in the OHL, he was a solid defensive forward who could also score, although his size was considered a major stumbling block in the eyes of most NHL scouts. In his first year with the Royals, 1980-81, Gilmour was 5'9" and 150 pounds.

Though he'd gain a couple of inches in his three years in Cornwall, he didn't add many extra pounds. What did add up in the OHL were his offensive numbers. After an early injury curtailed his effectiveness in Cornwall's 1981 Memorial Cup championship, he returned to score 46 goals and 119 points in 1981-82.

Cornwall repeated as Memorial Cup champions and Gilmour, who'd been passed over in his first year of draft eligibility, was selected by St. Louis in the seventh round, 134th overall. He was returned to junior hockey by the Blues for the 1982-83 season and set the OHL on fire with 70 goals and 177 points capturing the Eddie Poweres Trophy as the OHL's leading scorer. He set a record with a 55 consecutive games scoring streak and was named the league's most valuable player.

Still, Gilmour's size worried management in St. Louis and he almost began his pro career in Germany when he couldn't reach a deal with the Blues. St. Louis finally signed him and he joined the team two weeks before the 1983-84 season. Gilmour found himself near the bottom of the team's depth chart at center, but a depleted roster allowed him to play on the fourth line as a defensive specialist and he returned to his checking ways. The Blues' captain, Brian Sutter, nicknamed Gilmour "Killer" for his intensity and for his vague resemblance to Charles Manson.

After three full seasons hovering around 50 points and concentrating on checking, Gilmour put on weight, in his words, he "ballooned" to 165 pounds and he began to play a more open game. In the 1986 playoffs, he had 21 points in 19 games when the Blues came within a game of advancing to the Stanley Cup finals. The next season, 1986-87, he finished the regular schedule with a career-high 42 goals and 105 points and was selected to play for Team Canada in the Canada Cup. He scored two important goals in the series against the Soviet Union and was named the tournament's most valuable player.

After another solid season in St. Louis, Gilmour was traded to the Calgary Flames at the beginning of the 1988-89 campaign. In Calgary, Gilmour continued his strong play in the playoffs, adding 22 points in 22 games as the Flames won the Stanley Cup in 1989. Gilmour scored the series-winning goal in game six of the finals against Montreal. Halfway through the 1991-92 season, Gilmour became increasingly disenchanted with his pay from the Flames and an arbitrator's decision that saw his salary increase less than he expected. He decided to leave the team, but only a few hours later he was traded to the Toronto Maple Leafs in a blockbuster deal involving 10 players, the largest trade in league history.

Gilmour played his best hockey with the Leafs. He was a pesky defensive forward who seemed fearless in his checking. Offensively, he was the focal point of an improving team, setting a franchise record with 127 points in his first full season with Toronto in 1992-93. He became only the second Leaf after Darryl Sittler to register over a hundred points in a season and also led the team to within a game of the Stanley Cup finals, placing second in playoff scoring and leading the league with 25 assists. Gilmour placed second to Mario Lemieux in the race for the Hart Trophy as the league's most valuable player and won the Selke Trophy as the top defensive forward, a remarkable achievement for a player with such offensive numbers.

Gilmour had 111 points the next season, earning his second consecutive spot in the All-Star Game. He once again led the Leafs to the semifinals in the playoffs. Gilmour was named the team captain in 1994-95 before the lockout shortened season and remained a popular player in Toronto even as the team began to struggle. When the Leafs went into rebuilding mode midway through the 1996-97 season, Gilmour was sent to the New Jersey Devils. He spent one full season with the defense oriented Devils and was signed as a free agent by the Chicago Blackhawks in the summer of 1998. In the spring of 2000, he was traded to the Buffalo Sabres. Where his productivity lacked and he contemplated retirement. Then signed on as a free agent with the Montreal Canadiens in October 2001, and went on to play parts of two seasons with the Habs before he was dealt back to Toronto at the trading deadline in 2003.
