No. 1 pick Gavin McKenna makes NHL debut as Maple Leafs open season with loss to Canadiens

Gavin McKenna played his first regular-season shift as a professional Tuesday night, and by the final horn the Toronto Maple Leafs had lost to the Montreal Canadiens anyway. Eighteen years old and barely three months removed from being taken with the No. 1 overall pick in the 2026 NHL Draft, McKenna finished his long-awaited debut on the wrong end of a 3-2 defeat at Scotiabank Arena, a result that mattered less to most in the building than simply watching him play.

McKenna logged 15 minutes 19 seconds across 18 shifts, took one shot on goal, gave the puck away twice and finished a minus-2, numbers that will not appear in any highlight package. He opened the night on Toronto's second line between veteran center John Tavares and winger William Nylander, then slid to the third line once rookie Easton Cowan was bumped up. Nylander scored twice for the Maple Leafs, but three unanswered goals from Alexandre Carrier, Zachary Bolduc and Josh Anderson carried Montreal to the win, according to a recap from TSN.

"Not my best," McKenna said afterward, "but, yeah, I think I'm glad we're playing again tomorrow." It was a flat, workmanlike answer from a player who has been the presumptive face of Canadian junior hockey for four years and is now, officially, an NHL player.

The buildup to one shift

The Maple Leafs made McKenna's arrival a production befitting the weight of expectation around him. He took a ceremonial rookie lap around Scotiabank Arena before puck drop, a Toronto tradition for notable debutants, and the public-address introduction drew one of the loudest ovations of the night. McKenna called it, in comments carried by NHL.com, a moment that "almost gives me chills thinking about it," adding that his family and close friends were in the building to see it.

Toronto captain Auston Matthews, who authored his own famous four-goal debut a decade earlier almost to the day, offered a more measured take on what the night meant. "It's a pretty special moment," Matthews said. "You have so much family, so much support in your corner." McKenna, for his part, tried to keep the moment in proportion beforehand, telling the league's own site he had "high expectations" for himself but was not fixated on matching Matthews' opening act. "I just want to go out there and play my game," he said. "If I can contribute in ways like battling off the puck and things like that, I think that'll lead to a good night."

"He's adjusted really well, maybe better than we thought he would through these first 10 days," Toronto coach Jim Hiller said of McKenna heading into the opener.

How McKenna got here

McKenna's path to Tuesday night has been unusually well-documented for a teenager. Born in Whitehorse, Yukon, and a citizen of the Tr'ondëk Hwëchʼin First Nation, he became the first Yukon-born player picked first overall in a Western Hockey League bantam draft when the Medicine Hat Tigers selected him in 2022. He went on to lead the entire Canadian Hockey League in scoring in 2024-25 with 129 points, was named the CHL's top player and won a championship with the Tigers, according to the league's own account of his career published by the Canadian Hockey League.

Rather than stay in major junior for a final season, McKenna opted for the NCAA route, spending 2025-26 as a freshman at Penn State, where he posted 51 points in 35 games. The Maple Leafs made him the first-overall selection at the 2026 draft in Buffalo, a pick announced a decade to the week after Toronto used the same slot on Matthews at the same venue. He is only the third player in franchise history taken first overall, joining Matthews and Wendel Clark, who went first in 1985.

• Final score: Montreal Canadiens 3, Toronto Maple Leafs 2, at Scotiabank Arena
• McKenna's debut line: 15:19 ice time, one shot, two giveaways, minus-2
• Nylander scored twice for Toronto; Carrier, Bolduc and Anderson scored for Montreal
• McKenna was the No. 1 pick in the 2026 NHL Draft after leading the CHL with 129 points in 2024-25

A franchise still rebuilding around him

The loss extended a difficult stretch for a Toronto franchise that missed the playoffs last season for the first time in a decade, ending a run of nine consecutive postseason appearances. That collapse cost general manager Brad Treliving his job before the season had even finished and led ownership to hire John Chayka as GM and bring franchise icon Mats Sundin in as a senior hockey operations adviser. Jim Hiller was installed as head coach, and the roster around McKenna changed substantially over the summer, most notably with winger Mitch Marner's departure in a sign-and-trade to the Vegas Golden Knights and the free-agent addition of goaltender Sergei Bobrovsky.

Montreal, by contrast, arrived at Scotiabank Arena as a team on the rise, having reached the Eastern Conference final last spring before losing to Carolina. The Canadiens' win over an Original Six rival to open the season fit a young roster that has been steadily climbing the standings for two years.

None of that context stopped Tuesday's game from being, for one night, almost entirely about one teenager's first 15 minutes of NHL hockey. McKenna is expected to remain in Toronto's lineup for the foreseeable future rather than being returned to junior or sent to the American Hockey League, giving the Maple Leafs a chance to build his development into the fabric of a team trying to prove last season's playoff miss was an aberration rather than a trend.

What comes next

The Maple Leafs' next games this week will offer an early read on where McKenna fits in the lineup as the season settles in. Hiller will need to decide whether McKenna keeps his spot alongside Tavares or settles into a lower-pressure role further down the lineup while he adjusts to the speed of NHL play, something the coaching staff has praised him for absorbing quickly during training camp and the preseason. For a franchise that spent the offseason rebuilding around the idea that McKenna could eventually anchor it, the substance of his production will matter far more than the ceremony that preceded it, starting with whatever happens the next time he steps on the ice.
