The concept of the Science Fair with participation by several schools in Mississauga and later in the Peel Region was developed as a partnership between teachers dedicated to science education and the Rotary Club dedicated to service in the community.  Guy Marlatt, science teacher at Homelands Public School and a group of other local science teachers organized the science fair with the support and sponsorship by the Rotary Club of Clarkson (later and presently known as the Rotary Club of Mississauga West).  The first science fair in Mississauga was held in the spring of 1970 at the Sheridan Park Curling Club with the official opening by William G. Davis (Minister of Education at the time and later the Premier of Ontario).  The science fair grew in participation with more schools and students and support from the Peel District School Board and Dufferin-Peel Catholic District School Board and many other sponsors.  After a few years at different locations, the Peel Region Science Fair found a home at Erindale College, Mississauga (later known as the University of Toronto at Mississauga).
