Pierre Dorion has resigned and been relieved of his duties as general manager of the Ottawa Senators. President of hockey operations Steve Staios will take over as interim GM.

The team announced Dorion's departure after eight seasons in the role during a Wednesday news conference featuring owner Michael Andlauer, who purchased the team last spring, and Staois.

Dorion's firing came on the heels of Ottawa being docked a first-round draft choice for the club's role in an invalidated trade in 2022 between Evgenii Dadonov and the Anaheim Ducks that Andlauer said came with a 73-page document -- which he only received last week -- dictating how the Senators were "negligent in nature" and that was a final push to move on from Dorion.
