Wang Meng of China won the gold in 44.345 seconds while Radanova finished second in 44.374.

Leblanc-Boucher, a 21-year-old who's competing in her first Olympics, crossed in 44.759, getting to the line ahead of China's Fu Tianyu by less than a skate length. The close finish didn't matter though, since Fu was disqualified for cross-drafting.

Once she saw the final results, Leblanc-Boucher jumped into her coach's arms then gave him a high-five before taking a lap around the rink draped in a Canadian flag.

«I started completely on the outside and I knew I needed a good start,» she said. «My coach recommended I head diagonally towards the first turn and not in a straight line. I had to take the lead, but I wasn't able to.»

Wang held off Radanova by about the length of a skate blade as the Bulgarian skater made a desperate lunge for the finish, falling after she crossed the line and sliding into the padding.

Roberge, a 19-year-old from Quebec City, won the B final after finishing a disappointing third behind Wang and Radanova in the semifinals.

Kalyna didn't want to appeal

«Kalyna didn't want us to file the appeal,» Thibault said. «She was saying she wanted to beat the skaters on the ice and it's for her honour. But for me, I'd really like two medals and the rules are there to be respected.»
