About Us

Open to young people aged 6 to 20, theExpo-sciences is an essential scientific competition in Canada.

The first metropolitan area edition took place in 1961!

What is it about?

Each high school or college student progresses in the class that corresponds to their level:
Junior (secondary 1); Intermediate (secondary 2 and 3); Senior (secondary 4 and 5); College (1, 2 and 3e year).

Exhibitors, alone or in pairs, choose a subject to explore in one of the five identified scientific fields. Young people can propose design, experimentation or scientific popularization work.

Then, the exhibitors present the results of their project to a jury of experts and the public. The winners win various prizes.
