ABC Montessori

ABC Montessori’s Toddler and CASA campus is enrolled in the Canada-Wide Early Learning and Child Care (CWELCC) program to lower the cost of Early Childhood Education for Ontario families.

ABC Montessori has been a leader in early childhood education and K-5 elementary education since 1995. Our foremost priorities are to provide students with a friendly, nurturing, safe and supportive school environment where teachers  are caring, encouraging and dedicated to the overall success of every student. 

We offer a unique Montessori and traditional learning approach for toddler and pre-school children and a challenging, forward thinking elementary curriculum. In addition to our core academic curriculum, students explore the French language, Art, Music and Dance.

What current parents have to say about ABC Montessori


“At ABC Montessori, the principles of integrity, co-operation, responsibility, and respect are modeled by teachers, emulated by students, and practiced by all. While other schools are exclusive, not recognizing the cultural and religious celebrations of its student body, ABC Montessori is inclusive in acknowledging its cultural and religious diversity. Our daughter has learned tolerance, respect, and understanding”

– Mary Jo S. – Parent

“Seven years ago we decided to enroll our young daughter at ABC Montessori School, and as we look back, it is absolutely one of the best decisions we have ever made.”

– Vincent and Alice L
