Principal photography began in Toronto on June 22, 2015. The film was released in Canada on March 17, 2017, with release for the United States, United Kingdom and several other countries set for September 1, 2017.
During a pro hockey lockout, Doug 'the Thug' Glatt's (Seann William Scott) team, the Halifax Highlanders, has to contend with an influx of new players. With pro hockey suspended, media focus has descended on the lower league, and the owner of the Highlanders, Hyrum Cain (Callum Keith Rennie), seeks to capitalize on the attention. Before the opening game, Doug is made captain and leads his team out onto the ice. In a close fought game, Doug is goaded into a fight with the rival team's enforcer, Anders Cain (Wyatt Russell), an up-and-coming player with a violent streak, and the son of the Highlander's owner. Anders wins the fight, and with Doug badly injured, the Highlanders lose the game. Dealing with rehab, Doug decides to retire and accept a more stable job as an insurance salesman. At home, Doug's wife Eva realizes that she is pregnant, and she and Doug make preparations for their new child. Without Doug, the Highlanders go on a long losing streak, prompting the owner to push for changes. He signs several overseas players and pushes to add his own son to the team. Hyrum foresees Anders as the new captain of the Highlanders, and although the coach disagrees with the move, anticipating locker room dysfunction, Hyrum strongarms him into making Anders the new captain.
Meanwhile, Doug finds no joy in his new job, stuck in a dingy office, and he begins secretly training to get back into hockey. Doug visits his old rival, Ross "The Boss" Rhea, who has left hockey and now competes in a hockey fighting league, where he is the current champion. Doug convinces Ross to train him in southpaw fighting, as the injury he suffered fighting Anders has weakened his right arm. Ross agrees to train him, and Doug slowly begins to learn how to fight left-handed. Ross convinces Doug that if he joins the hockey fighting league and impresses, it could be a way to get back into minor league hockey. Doug takes Ross' advice, but the first fight ends up being a battle royale style brawl, instead of the one-on-one fights that Doug had witnessed before. Doug and Ross end up as the last two standing during the melee, but Ross is too hurt to continue and collapses before they can fight each other. In the locker room after the fight, Ross reveals that he has post-concussion syndrome, and doctor's have recommended that he stop playing, as one more bad hit could cause a permanent injury.
At the same time, the Highlanders have improved with Anders as the captain, but the team can't seem to improve enough to get into playoff position. Anders' self-sabotaging play, in which he constantly is being penalized for fighting, has kept the Highlanders outside of a playoff spot. In addition, Anders' aggressive and violent attitudes towards his fellow players keeps the whole team on edge, and their play suffers as a result. During another losing effort, Anders grows frustrated and ends up knocking out the entire opposing team. He is promptly suspended, and the coach demands a change. Hyrum, having seen Doug at the hockey fighting league, suggests that they add Doug back to the roster, secretly hoping that his addition will push his son to play better. Before Doug's first game back, Eva makes Doug promise that he won't fight, concerned for him now that they're about to be parents. Doug reluctantly agrees, and the Highlanders narrowly win in Doug's celebrated return. The Highlanders go on a winning streak, but when Anders returns from suspension, he goads Doug into being more aggressive. Doug and Anders interrupt a game during a dispute, and they are both suspended for the next game. During the game's afterparty, Anders provokes Doug into a fight, and when Eva sees that Doug has been fighting again, she kicks him out of the house.
Meanwhile, the Highlanders must win the last two games of the season to sneak into the playoffs. With Anders and Doug suspended, Hyrum decides to sign Ross, who has still been competing in the local hockey fighting league. To free up a spot, Hyrum terminates Anders' contract, fed up with his son's antics. While Ross helps the Highlanders to win the first of their last two games, Eva goes into labor, and Doug reconciles with her as they head to the hospital. After having her baby, Eva realizes that the same drive that led Doug to be with her during the birth, is the same drive that pushes him to want to defend his teammates on the ice, and she gives Doug her blessing to continue fighting. Having been kicked off the team, Anders rejoins his old team, as they will play the Highlanders in the last game of the season with a playoff spot on the line. The game is immediately chippy, with both Ross and Anders starting fights. As the game enters the third period with the game tied, Ross and Anders are involved in a scuffle, and Anders cheap shots Ross, checking him from behind into the boards. Ross is knocked unconscious, and while paramedics take him away on a stretcher, Doug enters the rink to fight Anders in retaliation.
Doug uses his southpaw training to beat Anders, but when Doug shows mercy, Anders threatens Doug, claiming that he will never stop coming for him until they are both like Ross, being carried out on stretchers. Realizing that his new family is more important to him than hockey, Doug uses his weakened right arm to level Anders, but throws his arm out and has to be carried off the ice. Hyrum rushes to his son's aid, where Anders tells him that he hates hockey, and the two appear to mend things between them. Having been told earlier that further injury to his right arm would be career-ending, Doug realizes that his hockey days are behind him. He watches as the Highlanders win the game in the final seconds, and during the celebration, he sets his stick down and goes home.Seann William Scott as Doug "The Thug" Glatt

Barry Hertz from Globe and Mail gave the film 3 out of 4 and wrote "Baruchel's sequel is everything Dowse's original film was, amped up a degree or three: The fights involving dim-bulb hero Doug (Seann William Scott) and his various rivals are bloodier, the locker-room talk is dirtier and the on-ice action is slicker. The unlikely project – how many made-in-Canada films spark a franchise? – doesn't quite reach the heights of the original film, which found surprising pathos in Doug's tale of sweet good guy to brutal goon. But it delivers on nearly every other scale, including standout performances from returning players Scott, Alison Pill and Liev Schreiber, as well as some bits of comic gold courtesy of series rookies Wyatt Russell, T.J. Miller and Jason Jones." Toronto Sun gave the film 3.5 out of 5, and stated "Violent, crude and really funny, Goon: Last of The Enforcers, works for the same reason the original Goon worked — you will love the characters." National Post gave the film a 1 out of 4.
