HAMILTON — Atlético Ottawa is back in the Canadian Premier League final. Nicolas Fleuriau Chateau sealed his hat trick with the game-winning goal 13 minutes into stoppage time to lift Atletico Ottawa past Forge FC 3-2 in the second leg of their semifinal at Hamilton Stadium on Saturday. The defending champion Ottawa won the semifinal 5-4 on aggregate after the two sides drew 2-2 in the first leg last week. Fleuriau Chateau scored in the 25th and 84th minutes for the visitors. Hoce Massunda put Forge on the board five minutes into first-half stoppage time, while Daniel Nimick scored two minutes before Fleuriau Chateau’s winner on a penalty kick. Ottawa will next face the winner between Cavalry FC and FC Supra du Québec in the other semifinal later Saturday.
