For the 2006 season, Frizell returned to her native Ontario to train. She continued to progress and won her first Canadian national title in 2007. She also qualified for the 2007 Pan American Games where she placed seventh. On November 1, 2007, Frizell relocated to Kamloops, British Columbia to train under the guidance of former world record holder Anatoliy Bondarchuk. During the 2008 season, Frizell broke the Canadian senior women's hammer throw record four times and improved her personal best by over three meters. Her personal best throw of 70.94 meters was in July 2008 at the Canadian Track and Field Championships in Windsor, Ontario. That mark qualified her for the 2008 Olympic Games in Beijing, where she placed 33rd out of 50 competitors.
