The following season, Cloutier began a four-year career in the Ontario Hockey League (OHL), debuting with the Sault Ste. Marie Greyhounds. He played in 12 games (4–6–0) with the Greyounds, recording a 4.62 GAA in the regular season. In the 1993 OHL playoffs, Cloutier appeared in an additional four games, winning one and losing two, as part of the Greyhounds' run to the J. Ross Robertson Cup Finals. Although they lost the league championship to the Peterborough Petes four-games-to-one, the Greyhounds still qualified for the 1993 Memorial Cup as the tournament's host team. The Greyhounds met the Petes again in the Memorial Cup final, defeating them by a 4–2 score. Cloutier did not appear in any Memorial Cup games, in lieu of starter Kevin Hodson. During his rookie season in the OHL, he also played in five games at the Junior A level with the Timmins Golden Bears of the Northern Ontario Junior Hockey Association.
