Natalie Lambert is a Canadian open water swimmer who specializes in butterfly. She set a record for crossing Lake Erie in butterfly in 2008 at the age of 14, and another record for being the youngest to cross Lake Ontario in front crawl on 28 August 2007. She was trained by her coach Vicki Keith.
Natlie's older sister Jenna became the first female with a disability to swim across Lake Ontario in July of 2006. Her swims have raised money for the “Swim the Difference” campaign for the Kingston YMCA's "Y Knot Abilities" program, run by Vicki Keith and supported by her husband John Munro in his Y Knot Marathon. The program gives children with disabilities a chance to find success through achievement, in a fun and friendly environment.
