"THERE IT IS!!!!!," tweeted Canadian women's hockey player Haley Wickenheiser after the goal. "Matheson..unsung hero, scores on one of canadas few chances...so proud!! WAY TO GO."
France completely dominated the second half and had several chances to score. But Matheson latched on to a loose ball in the second minute of added time and was unmarked when she volleyed the ball past France goalkeeper Sarah Bouhaddi.
"DIANA MATHESON!!!!!!!! #CANWNT #SOCCER #BRONZE," tweeted kayaker Adam van Koeverden, who won silver in the K-1 1,000-metre race on Wednesday.
The win marked Canada's first Summer Games medal in a traditional team sport since 1936, when the men's basketball team won a silver.
"WE DID IT! This is the happiest day of my life! Thank you to every single person that never stopped believing in us! This was for you CANADA," tweeted Canadian soccer player Jonelle Filigno after the game. "No words to describe this moment and journey for us!"
Former CFL running back and current bobsledder Jesse Lumsden sent his congratulations to Canadian captain Christine Sinclair and teammates Kaylyn Kyle and Melissa Tancredi.
"@sincy12 @KaylynKyle @MelTancredi14 and all the other ladies woot woot!," tweeted Lumsden. "Watching the highlights again! #bronze mothercanuckin awesome!"
Former Olympic champion speedskater Catriona Le May Doan also sent her well wishes to the Canadian women.
"Congrats to #CanWNT @canadasoccerEN @CDNOlympicTeam," tweeted the two-time gold medallist. "What a superb example of always believing in your team! #inspiration."
Prime Minister Stephen Harper even got in on the action.
"Congratulations to our gutsy women's soccer team on their bronze medal win!," Harper posted on his official feed. "All of Canada is proud of you!"
