The Durham Regional Science Fair (DRSF) is an annual event hosted in early April by the Faculty of Science at Ontario​ Technology University in Oshawa ON L1G 0C5.​
​
​​It gives elementary and secondary school students (in grades 4 to 12) as well as home-schooled students from Durham Region an opportunity to present their science projects to the judges, their teachers, their parents, fellow students and the public.  Everyone who participates is a winner because they have asked questions, searched for answers and have gained more understanding about the world around them.​
