Our school originally opened in 1958 as Cedar Grove Public School. In 1978, we became part of an amalgamation of three schools Wilmington, Cedar Grove and Dufferin Heights Junior High under the name Charles H. Best Elementary and Middle School, East And West. In June 2002, Charles H. Best West became a  school on its own, offering programs for Junior Kindergarten to Grade 4. During 2003-2004, the school community completed the TDSB process to change our name to Wilmington Elementary School. In 2018 our school became a JK-Grade 3 School. As well as our vibrant elementary program, Wilmington also an EarlyON Parenting Centre and Wilmington Best Child Care.
