The Toronto Maple Leafs pulled off one of the biggest trades of the offseason on Monday, sending winger Matthew Knies to the Columbus Blue Jackets as the centrepiece of a six-player deal that brought forward Kirill Marchenko to Toronto. The blockbuster was finalized just one day before the start of the 2026-27 NHL regular season.

What the Maple Leafs gave up

The Leafs traded top-line winger Matthew Knies, forward Steven Lorentz, defenseman Emil Andrae and a 2027 second-round pick for Marchenko, forward Miles Wood and goaltender Elvis Merzlikins. The second-round pick heading to Columbus originally arrived in Toronto as part of an earlier trade involving Bobby McMann.

The centerpiece of the deal for Columbus is Knies, a power winger entering his fifth NHL season and signed through 2031, who had 66 points in 79 games last season with 23 goals and 43 assists. His contract carries a $7.75 million average annual value. Knies had seen his name surface in trade rumours for at least two seasons before the deal finally came together.

Lorentz, 30, is signed through 2028 at a $1.35 million AAV, while Andrae, 24, is a defenseman the Leafs had acquired from the Philadelphia Flyers earlier in the offseason.

What Toronto received in return

Marchenko, 26, led the Blue Jackets in goals in each of the last three seasons, amassing 81 goals in 233 games, and had 208 points in 292 career games with Columbus after being drafted 49th overall in 2018. He is expected to slot onto Toronto's top line alongside star centre Auston Matthews.

Marchenko's departure from Columbus had been building for months. A pending restricted free agent, he had been in the middle of trade rumours throughout the summer, and speculation especially ramped up in recent weeks when he implied to the media that he didn't want to sign long-term with the Blue Jackets. Asked directly whether he wanted to keep playing in Columbus, Marchenko offered a brief but telling response: "I want to play hockey. It's all I can say right now."

The Blue Jackets are retaining some salary on Merzlikins as part of the deal. Merzlikins is currently set to miss a significant amount of time following surgery, so it remains unclear how quickly he could factor into Toronto's plans in net.

Marchenko signs long-term with Toronto

Almost immediately after the trade was completed, the Leafs locked up their new winger. Marchenko's agent, Dan Milstein, announced that Toronto had signed him to a six-year extension with a $12.5-million cap hit. That deal is reportedly worth $75 million over six years.

The extension signals that Toronto views Marchenko as a foundational piece moving forward rather than a short-term rental. Beyond simply being a stronger overall talent than Knies, analysts note his skill set is well suited to the Leafs' needs, giving them a player capable of running with the likes of Matthews and William Nylander for added offensive upside.

Why Columbus made the move

For the Blue Jackets, trading their leading goal-scorer was a difficult but calculated decision once it became clear Marchenko was not going to commit long-term. As hard as it was to move their best forward, general manager Don Waddell still managed to acquire serious value in return, given that everyone knew Marchenko wasn't going to sign a long-term deal in Columbus.

Knies now becomes a foundational piece in Columbus. He arrives as the centerpiece of the return, a 6-foot-3 power forward with top-line upside who immediately becomes one of the Blue Jackets' most important young players, signed to a team-friendly deal with five years remaining at $7.75 million annually.

What comes next

The trade caps off an eventful offseason under new Leafs general manager John Chayka, who has reshaped the roster with several notable moves in recent months. With training camp wrapped up and the regular season about to begin, both Toronto and Columbus will now need to integrate their new pieces almost immediately, with Marchenko expected to debut alongside Matthews right out of the gate while Knies steps into a leading role in Columbus.
