||Meghan Agosta joined the Canadian national team in August of 2004, though she would not suit up for the team until the following summer at the 2005 Four Nations Cup.
At the 2006 Olympic Winter Games in Turin, Italy, Agosta was the youngest member of Canada's gold medal-winning team and scored a hat trick on her 19th birthday against the Russian team.
In 2010, the Olympics were on home soil in Vancouver, British Columbia and Agosta was again Canada's scoring star. She scored nine goals, a tournament record and added six assist en route to helping Canada to the gold medal. For her efforts Agosta was named tournament MVP.
At the 2014 Olympic Games held in Sochi, Russia, Agosta would score three goals and add an assist, helping Canada to the gold medal-victory. The win was the fourth consecutive for Canada and the third for Agosta.
