Ellington Montessori School was founded in 1990 by Ms. Deborah L. Renwick. Ms. Renwick opened the school with the purpose of operating a single Casa classroom accommodating 20 students. By the end of the first year, enrolment had increased substantially and expansion was on the horizon. The fall of 1992, the first elementary class was opened and the school grew over the next decade to include classes up to the 8th grade. Eventually, EMS outgrew its cozy Lawrence Avenue. campus, and in February of 2013 moved to its current location at 40 Cowdray Court, just north of the 401 off of Kennedy Road, in Toronto. EMS’ new home is a single-story building boasting 20,000 square feet of space, situated on two and a half acres of land.
