After winning a bronze medal in the vault final on Saturday, Chant earned her second trip to the podium with a strong floor routine that topped the field with a score of 13.750 points.
Dementyeva placed second with 13.575 points and Noel Van Klaveren of the Netherlands was third at 13.475.
Many of the competitors seemed to be having trouble with a bouncy floor mat but Chant had no complaints.
“Every floor is a little bit different and this one didn’t cause me any problems,” said Chant. “I had a lot of confidence going into the final and knew I had a good chance for a medal if I hit my routine.”
Chant has been one of the busiest gymnasts in the world this winter competing at four international events, including three World Cups, in the last month after moving up to the senior Canadian team following a stellar junior career.
“It’s tougher mentally than physically to compete so much and to be away from home for so long,” said Chant, who is coached by former Romanian star gymnast Cristina Bontas and her husband Gabi Tantaru at World Class Gymnastics in Hamilton.
“It’s been a real journey and I’ve learned a lot going up against so many more experienced gymnasts. I’m looking forward to working hard to keep on improving.”
Chant will turn her attention now on getting ready for the Canadian championships in late May with the goal of winning a spot on the 2013 world championship team.
