On May 22, 2007, Karine Sergerie became the first Canadian to ever win a gold medal at the World Taekwondo Championships, held this year in Beijing, China.

Karine came back from a 3-0 deficit to beat Park Hye-Mi of South Korea 4-3 in extra time for the women's 63kg title.

Although in the final match she was trailing 3-0 following the first two rounds, Karine scored three straight points and then finally scored the winning point 57 seconds into the sudden-death round to win the championship.

"(When I was trailing,) I kept thinking about everything I had put into this tournament. There was no panic. My coach told me to be patient, and wait for the opportunity to come. I followed his orders and I won the game," said Sergerie, who had won a silver and a bronze medals in previous championships.
