The NHL's New Retained-Salary Rules Kick In Sept. 16 — And They Change the Leafs' Trade Math

The loophole closes on Sept. 16

The new NHL retained salary rules take effect on Sept. 16, 2026, and they quietly remove one of the most useful tools a cap-strapped team like the Toronto Maple Leafs has had for the past decade. Under the collective bargaining agreement extension that the league and the NHL Players' Association ratified in the summer of 2025, retained-salary transactions involving a single player's contract can only occur once every 75 regular-season days. Days outside the regular season — playoffs, training camp, the offseason — do not count toward that total.

Read that carefully, because the phrasing does the work. It is not a ban on retention. Teams can still retain up to 50 per cent of a contract, and clubs are still capped at three retained contracts at any one time. What disappears is the ability to stack two retentions on the same contract in quick succession, which is how the most aggressive cap gymnastics of recent trade deadlines were executed.

For a team that has spent every summer of the Auston Matthews era squeezing under the ceiling, this is not a footnote. It is a structural change to how John Chayka can solve problems.

What the double-retention trick actually was

The mechanic was simple and legal. Team A trades a player with 50 per cent retained to Team B. Team B, acting as a broker rather than a destination, immediately flips that player to Team C with another 50 per cent retained. The contender at the end of the chain gets the player at 25 per cent of his original cap hit, and the middleman collects a draft pick for doing nothing but absorbing paper for an afternoon.

The Trent Frederic deal in 2025 was the version that finally got the league's attention, and it was far from the only one. Salary brokering became a recognized deadline business, with rebuilding teams selling their cap space and their retention slots the way they sell veteran rentals.

Starting in September, the second retention on a given contract has to wait 75 regular-season days. Since the regular season runs roughly late September through early April, 75 regular-season days is most of a season. A player retained in a July trade cannot be re-retained until well past the following trade deadline. In practice, the same-day double retention is dead.

Why this lands squarely on the Morgan Rielly situation

Toronto's most-discussed trade asset is also the one most affected. Morgan Rielly carries a $7.5 million cap hit through 2029-30 and holds a full no-move clause for the coming season. Any team acquiring him is taking on four more years of a defenceman coming off the worst statistical stretch of his career.

Retention was always going to be part of the solution. Toronto retaining 50 per cent brings Rielly to $3.75 million, a number a lot more clubs can stomach. Under the old rules, a third team could then take him at $1.875 million, which opens the market to almost anybody. Under the new rules, that second step is unavailable for most of a season.

That has two consequences. First, it narrows the list of teams that can realistically absorb Rielly, because the deal has to work at $3.75 million rather than at a broker-assisted $1.875 million. Second, it raises the value of doing the deal now, before the new CBA takes effect on Sept. 16 — though with Rielly holding a full no-move clause and reportedly a short list of acceptable destinations, urgency on Toronto's side does not translate into leverage. We covered the current state of that standoff in our look at Chayka saying he does not anticipate a Rielly move while insiders stay skeptical.

Deferred salary is gone too

The same CBA package eliminates deferred salary in all new contracts signed after the agreement takes effect. Existing contracts with deferred money are grandfathered, but no new deal can push payments into the future.

Deferrals were never a mainstream tool, but they were a real one for teams trying to make a high-cap-hit contract palatable to an owner rather than to the cap sheet. Removing them takes another piece of creative structuring off the table. Combined with the term limits — seven years to re-sign your own player, six for an outside free agent — the direction of the new agreement is consistent: fewer clever structures, more straightforward contracts.

We wrote about the term change and what it means for Toronto's next big negotiation in our piece on the seven-year limit and the eventual Auston Matthews extension.

The deadline gets harder, not easier

Stack the new retention rule on top of the playoff salary cap that also arrives with this CBA, and the trade deadline changes character entirely. Teams will have to be cap compliant in the playoffs under the regular ceiling, which ends the long-standing practice of banking LTIR relief in March and cashing it in during April. We broke that down in our look at the playoff salary cap and what it does to Toronto's Domi LTIR plan.

The combined effect is that acquiring an expensive player in-season becomes much closer to what it looks like on paper. You need the actual room, you cannot manufacture a discount by routing the contract through two other franchises, and you cannot hide the number once the playoffs start.

For Toronto specifically, that is a mixed bag. The Leafs have historically been buyers who needed exactly those tricks. But they have also been the team most exposed when a rival used them better. A flatter playing field is not obviously bad for a club with an $104 million ceiling to work under and a roster that is already close to it.

What the new NHL retained salary rules mean for how Chayka builds

The practical lesson is that salary has to be moved cleanly, not laundered. If the Leafs want to add a top-four defenceman, the money has to come off the books in a real trade with a real partner willing to take a real contract. There is no longer a mechanism that lets a third party shave a cap hit down to something cosmetic in exchange for a fourth-round pick.

That favours teams with genuine cap space and clean sheets, and it penalizes teams carrying multiple contracts they regret. Toronto is closer to the second group than the first. Ekman-Larsson at $3.5 million, Dakota Joshua at $3.25 million and Rielly at $7.5 million are all deals that would be easier to move under the old rules than the new ones.

Chayka arrived in May 2026 with a reputation for finding edges in the system. The system just removed one of the biggest edges available. Our contracts page tracks every commitment on the books, and the standings page will show soon enough whether the new constraints hurt Toronto more than the field.

What's next

The CBA extension runs from Sept. 16, 2026 through Sept. 15, 2030, alongside the move to an 84-game regular season and a shortened four-game preseason. Every rule discussed here arrives at once.

Between now and then, there is a narrow window where the old retention mechanics still apply. If a team wanted to execute one last brokered deal, August is the time. Whether Toronto is on either end of one is the question worth watching — and given how the Rielly file has gone all summer, betting on a resolution in the next seven weeks requires more optimism than the evidence supports.
