Rosie MacLennan did Canada proud during the 2012 summer games. The King City native was already an incredible gymnast before her performance in London, but she's since gained star status within the Canadian program. This of course, is due to the fact that she finished as Canada's only gold medalist, with a deciding win in women's trampoline. Before she beat out China's Huang Shanshan, the hope faded for a first place finish. Her lone gold win has cemented her as a Olympic hero. It's safe to say that the girl from a small town in Ontario, has truly come a long way since volunteering at the Vancouver 2010 Olympics.
