About us

THEExpo-sciences is a scientific competition open to young people aged 6 to 20. It’s a must-see in Canada. 

The first Expo-sciences of the metropolitan area took place in 1961!

The young people who compete are called exhibitors.

Every year, we organize scientific gatherings for elementary school children from Montreal, Montérégie and the North Shore. These scientific gatherings bring together the regional finals of Expo-sciences Hydro-Québec – primary component as well as the regional finals of the Défi apprenti génie. In addition, facilitators of the Resourceful – scientific activities will be present to provide scientific experiments to the public and students.

What is it about?

IMPORTANT: all projects must go through “Ethics and Regulations” platform in order to ensure the necessity (or not) of requesting an ethics or regulations form and this BEFORE starting the project.

Each primary school student progresses in the class that corresponds to their level: Juvenile 1: 1st and 2nd years (1st cycle of primary) Juvenile 2: 3rd and 4th years (2nd cycle of primary) Juvenile 3: 5th and 6th years (3rd cycle primary)
