The 35-year-old said he will retire after the Montreal Impact plays their final regular season game on Saturday against the New England Revolution.
''It's just been enough for me,'' Sutton said Friday after his last practice. ''I've had my fill of soccer on the field.
''I've done things I'm proud of and I think it's time. I'm older. I have more grey hair now. It's time to move on.''
Sutton played only 24 minutes of one regular season game in Montreal's expansion MLS season and, at his request, won't be dressed for the season finale.
''I'm going to watch and enjoy it — that's the way I want it now,'' he said.
''He said he didn't want to disturb anything we're doing and he knew it was important for us to get a win,'' said coach Jesse Marsch. ''He's a great man and I appreciate that.''
The six-foot-six Sutton was Marsch's roommate in his rookie season as a pro with the Chicago Fire in 1999.
Sutton played for the Impact in the A-League and the United Soccer Leagues from 2001 to 2006, winning a championship while taking most valuable player honours in 2004.
He joined Toronto FC for its expansion season in 2007, although he suffered a concussion while training with Canada's national team and did not return until the following season.
Sutton moved in 2009 to the New York Red Bulls, who loaned him to Montreal midway through last season. He stayed on with the club when it joined MLS.
He played 16 times for Canada.
The Hamilton native intends to stay in the Montreal area with his family and plans to remain active in soccer in some capacity.
''Playing for your country was special,'' he said. ''That was the highlight for sure.
''And winning a championship here in 2004 was exciting. There were numerous times I've enjoyed the soccer, not only on the field but off it as well. I played with some great players and great people.''
It may also be the final match for 39-year-old striker Eduardo Sebrango, who may not be kept on after the season. The long-serving Impact forward saw only 109 minutes of action this season.
He will dress for the season finale, and perhaps may get on the field late in the game.
Marsch lauded both players for helping teammates adjust to a new club and a new city and easing the transition to MLS.
''They were able to translate what it's like to be here and to lead by example,'' said Marsch. ''Greg had expansion experience with Toronto and he'd share things with me about what he'd learned there.
''He was helpful on a lot of levels.''
