Programs
At DMS Montessori Preschool and Daycare Inc., we believe every child deserves an individualized learning experience that supports their unique growth and development. Our Montessori programs are carefully designed according to each child’s age, readiness, interests, and developmental needs.
As a fully licensed and 100% accredited Montessori school, DMS Montessori proudly upholds the highest standards in early childhood education and authentic Montessori programming. Our accreditation reflects our commitment to excellence, professionalism, educational integrity, and the consistent delivery of genuine Montessori education.
Our Bambini program provides a warm, nurturing, and carefully prepared environment for our youngest learners. Through gentle guidance, sensory exploration, language exposure, movement, and practical life experiences, children begin developing independence, confidence, coordination, and trust in their surroundings during these foundational early years.
Our Pre-Casa program fosters independence, confidence, cooperation, attentiveness, and a love of learning through hands-on exploration and Montessori activities designed specifically for early learners.
In our Casa program, children engage in a rich curriculum that includes practical life, sensorial studies, culture, mathematics, language, grace and courtesy, music and movement, and circle time. French integration is also incorporated into the curriculum, helping children build early language skills and cultural awareness. Through these experiences, children gain a strong understanding of both their environment and the world around them. Parents are often amazed by the knowledge, independence, and confidence their children develop at such a young age.
DMS Montessori Preschool and Daycare Inc. operates in accordance with the Ontario Ministry of Education and the Child Care and Early Years Act (CCEYA), meeting all provincial standards and regulations while delivering authentic Montessori education every day.
What sets DMS Montessori apart is our commitment to truly living the Montessori philosophy. We are more than a preschool program — we are an authentic Montessori school focused on nurturing independence, respect, responsibility, concentration, and a lifelong love of learning.
While many programs may offer Montessori-inspired, French integration, or play-based learning, DMS Montessori is proud to provide fully accredited Montessori education grounded in authentic Montessori philosophy and methodology. For families wishing to continue their child’s Montessori journey into the elementary years, we are happy to help guide and support that transition.
