Canadian IChO Program History

The International Chemistry and Physics Olympiads have risen from very humble beginnings in 1967 when only three nations from Eastern Europe participated. The International Chemistry Olympiad (IChO) continues to be an annual competition, now involving up to 100 nations,  whose goal is to encourage excellence in high school chemistry education and learning throughout the world. IChO is the most prestigious global chemistry competition Canadian students can compete in at the high school or CÉGEP level.

Canada first participated in the International Chemistry Olympiad in 1985. Since this time, Canadian chemistry students have won 9 gold, 32 silver, and 63 bronze medals, along with 8 Honourable Mentions. A complete list of past Canadian students is below. In 1997, the Physics and Chemistry International Olympiads were held in Sudbury and Montreal, Canada . This was the first time that both IChO and IPhO were hosted by the same nation in the same year.

L'Olympiade internationale de chimie (OIC) est toujours une compétition annuelle, à laquelle participent maintenant jusqu'à 100 nations, dont le but est d'encourager l'excellence dans l'enseignement et l'apprentissage de la chimie dans les écoles secondaires du monde entier. L'IChO est la plus prestigieuse compétition mondiale de chimie à laquelle les étudiants canadiens peuvent participer au niveau secondaire ou au niveau des CÉGEP.

Le Canada a participé pour la première fois à l'Olympiade internationale de chimie en 1985. Depuis, les étudiants canadiens en chimie ont remporté 9 médailles d'or, 32 d'argent et 63 de bronze, ainsi que 8 mentions honorables.
