NHL Prospect Challenge: Leafs Open in Gatineau, McKenna Unclear

The NHL Prospect Challenge gives Toronto its first hockey of the 2026-27 calendar this week, and the biggest question about it is whether the most famous player in the organization will be there. The Ottawa Senators host the four-team tournament at Centre Slush Puppie in Gatineau on Sept. 12 and 13, with Toronto, Montreal and Winnipeg filling out the field. The Maple Leafs play the Senators at 6 p.m. on Saturday and the Jets at 1 p.m. on Sunday. Gavin McKenna has told reporters his participation is still up in the air.

That is the honest state of it four days out. Toronto has not released a roster, and the club has an obvious incentive to be cautious with a No. 1 overall pick heading into a compressed main camp. But the tournament matters regardless of whether McKenna dresses, because for a large slice of Toronto's prospect pool it is the only competitive evaluation they will get before the Marlies open.

The NHL Prospect Challenge schedule and format

The event is a straightforward two-day, four-team round of games rather than a bracket. Montreal opens against Winnipeg at 1 p.m. on Sept. 12, followed by Ottawa against Toronto at 6 p.m. On Sept. 13, Winnipeg plays Toronto at 1 p.m. and Montreal plays Ottawa at 6 p.m. Every club gets two games. Tickets started at $20 when they went on sale in late June.

Gatineau is a sensible host. The building is small enough that scouts and development staff can actually watch, and the four organizations involved are close enough geographically that travel does not eat into a schedule that is already tight. Under the new collective bargaining agreement, the main NHL camp is capped at 13 days for established players and the exhibition slate is down to four games. Rookie tournaments have quietly become more important, not less, because they are the one place a 19-year-old can play meaningful minutes without competing against a veteran for them.

The McKenna question

McKenna said his Gatineau plans were unsettled, and there is a defensible case on both sides.

Playing him makes sense if the organization wants him on the ice as much as possible before the main camp compresses everything. Two games against other teams' prospects is a low-stakes environment to shake off the summer, get used to professional pace and build chemistry with the young players he may spend years alongside.

Sitting him makes sense if Toronto believes the rookie tournament tells them nothing they need to know. McKenna is not competing for a job at that level. The Leafs already expect him in the top six with power-play minutes, and the real evaluation happens in the four exhibition games where he can play against NHL lineups. There is also a straightforward injury-avoidance argument: rookie tournaments are fast, loose and physical, and the downside of a bad hit in a September showcase is enormous relative to the upside.

If we had to guess, Toronto plays him in one of the two games and holds him out of the other. That splits the difference and it is what teams in this position usually do. Either way, the more consequential questions about him — who he plays with and how much rope he gets — get answered later in September.

Who else should be there

Toronto has not announced its roster, so anything specific is projection. But the shape of the group is predictable: 2026 draft picks who are in junior or pro hockey, players already signed to entry-level or AHL deals, and a handful of invitees.

The names worth tracking start with the defencemen. Ben Danford is entering what should be his first full professional season and is the most NHL-plausible blueliner in the system. Alexander Bilecki was one of the more encouraging pieces of Toronto's July development camp. Vincent Borgesi, Brandon Buhr and Hayes Hundley are all signed and in the pro pipeline.

Up front, Zach Olsen and Brody Pepoy are the 2026 selections most likely to appear. Toronto's NCAA-committed picks — Cooper Williams and Ethan MacKenzie, both bound for North Dakota — are less likely to be involved, since college schedules and eligibility considerations generally keep those players away from pro showcases.

In goal, the interesting name is whoever the Leafs choose to give the workload to. Patriks Plumins is off to Chicoutimi in the QMJHL, and Juuso Ainasto is the other 2026 pick in the crease. Artur Akhtyamov is past this stage of his development and belongs in the main camp fight.

Easton Cowan is the one borderline case. He is no longer a prospect in any meaningful sense after an 18-point Calder Cup run with the Marlies, and there is a strong argument that his September is better spent at the main camp fighting for the top-nine role Toronto needs him to take. Teams occasionally send a player in that position to a rookie tournament to captain it. More often they do not, and the Leafs have every reason to keep his legs fresh for the four exhibition games that will actually decide his role.

What a rookie tournament actually tells you

Not much about the top of a prospect pool. Everything about the middle of one.

Nobody has ever learned anything useful about a first-overall pick from two September games against other teams' 19-year-olds. What these events do reveal is who among the third- and fourth-round picks, the college free agents and the AHL contract guys can handle pace. A player who looks a half-step slow in Gatineau is going to look two steps slow in the AHL. A player who drives play against that competition has earned a longer look at main camp, which is exactly the kind of thing that matters when Toronto's prospect pool ranks 15th league-wide despite the lottery win.

There is a development-staff dimension too. Hayley Wickenheiser's group ran a 53-player development camp in July, and this is the first chance to see whether anything from that week carried over. The Marlies are also under new leadership after John Gruden was promoted to Jim Hiller's NHL staff, and the players in Gatineau are the ones who will decide whether the Marlies' development year produces anybody.

The Ottawa and Montreal context

The opponents are worth a note. Ottawa's group includes Carter Yakemchuk on defence and goaltender Lucas Beckman, and the Senators have built one of the more respected young cores in the Atlantic. Montreal's pipeline has been the model everyone in Toronto has been told to envy for two years, and the gap between the two prospect pools is the entire argument behind the 28-point gap the Leafs are trying to close.

That does not make these games important in the standings sense. It does make them a useful visual. If Toronto's teenagers look overmatched by Ottawa's and Montreal's, that is not nothing — it is a data point in an argument that has been running all summer about whether one lottery win actually fixed anything.

What's next

Rosters should be announced in the next day or two, and McKenna's status will be settled with them. After Gatineau, the main group convenes for a camp capped at 13 days, four exhibition games against Montreal on Sept. 19 and Ottawa on Sept. 23, and a season opener against the Canadiens on Sept. 29.

Two games in Gatineau will not change any of that. But for a couple of dozen players in Toronto's system, it is the first and possibly only chance to make somebody in the front office write their name down. Follow the pipeline on our draft page.
