Aucoin did not have his name added to the cup as he did not play in any of the playoff games, but can be seen on the ice during the celebration and did receive a championship ring.

[4] With the intention to bolster the offense of Maple Leafs affiliate, the Toronto Marlies, Aucoin was directly assigned to the AHL to start the 2012–13 season.

In 41 games, he produced 6 goals and 12 points in a checking line role and helped the Islanders return to the playoffs for the first time since 2007.

On June 13, 2014, after failing to secure a tryout with any other NHL team, Aucoin signed a two-year deal with Swiss club, HC Ambrì-Piotta of the National League A.

Unable to progress to the playoffs, Aucoin left Switzerland after one season, to sign a one-year contract in Germany with EHC München of the Deutsche Eishockey Liga (DEL) on June 19, 2015.

[9] Aucoin returned to Massachusetts following his 17 year professional career, spending four seasons (2018–2022) within the coaching ranks of the EHL with the Boston Jr. Rangers and Worcester Jr. Railers.
