The team win was sparked by Oduro's goal and a stellar corner delivered by Pavel Pardo.
Dominic Oduro scored in the first half and Dan Gargan put the game away in the second for the Fire, who won for the first time since March 26, 2011.
"It was just great to get the win because I thought the team played well," coach Frank Klopas said.
Chicago got on the scoreboard early as Fire defender Gonzalo Segares crossed the ball to Oduro in the penalty box and the Ghanaian forward flicked the ball past Toronto’s goalkeeper Milos Kocic in the 16th minute.
The finish was Oduro’s eighth goal of the season and the momentum clearly shifted toward Chicago as it became more confident in possession and moving the ball forward.
"You've seen goals where he's able to switch the ball over from his left foot and looking up instead of sometimes just hitting it with power," Klopas said. "But I think he has the right mentality because as a forward when you miss four chances, you always have to be ready for the next one."
Continuing his steady play since joining the Fire, former Mexico midfielder Pavel Pardo cemented the game for Chicago creating a goal off of a set piece. Pardo launched an deadly corner that was headed in by Fire right back Gargan in the 69th minute.
"He's just a solid guy that's experienced in the league," said Klopas of Gargen. "He can give us depth, step in and start, he's a competitor, has a great attitude every day and can play different positions on the field."
Despite being held scoreless, Toronto FC dominated possession holding the ball for almost 60 percent of the game but couldn’t put its chances. The Reds only had two of its 13 shots on target. The Fire’s win puts it ahead of the New England Revolution in seventh place with 24 points. Gargan believes the result will spark the team during the final eight games of the season.
“Hopefully this is just the start and the spark we’ve been looking for," said Gargan. "We got a little lucky tonight with a couple of posts they had, but that’s the way the game works sometimes. It was important for us to finish the 90 minutes out and get the three points. “
Toronto FC remains last in the Eastern Conference with 23 points.
