Virtual 2021
About Canada-Wide Science Fair
The weeklong Canada-Wide Science Fair (CWSF) brings together the country’s top young scientists in grades 7-12/Cégep. It’s been held every year since 1962, except 2020 when it was cancelled due to COVID-19 restrictions.
In addition to scientific, social, and cultural activities, the 500 finalists compete for medals, cash prizes, scholarships and exclusive opportunities.


In 2021, the CWSF will be going virtual from May 17-21.
