Developing Canada's capacity for high-quality research in science, technology & engineering since 1974.

The WWSEF is open to all young researchers in grades 7 to 12 in schools from the areas served by the Waterloo Catholic, Waterloo Region, Upper Grand, and Wellington Catholic District School Boards.

If you are in the above areas and your school does not have a science fair or you are home-schooled, you may participate as an Individual Entry. If you are an Individual Entry, make sure that you have an adult Supervisor who is monitoring of your project.

The COVID-19 situation is evolving and there have been a number of recent announcements that have a significant impact on large gatherings such as regional science fairs.

As a result of these and other factors, we are planning to hold a virtual WWSEF this coming year.

We are in the process of creating an online portal which will allow exhibitors to:
  • register their entry,
  • upload image(s), etc. of their project,
  • connect with judges for inteviews on the day of the Fair,
  • post results/awards

  • The fair will be held virtually on April 15, 2021.
  • Registration will begin in early February. The date will be published as soon as we get things organized.
  • The registration deadline will be March 12, 2021.

This website has been created as a reference guide for exhibitors, teachers and advisors/mentors.
Included are tips on planning and carrying out scientific studies or experiments, lists of regulations, judging criteria, and information on eligibility, registration, program and awards at both the regional and national levels.

Website hosting has been donated by the University of Waterloo Faculty of Science.
