The Montessori method is an educational approach developed by Dr. Maria Montessori that emphasizes child-led learning, hands-on activities, and mixed-age classrooms. Children choose their own activities from a range of options, learning at their own pace. Montessori classrooms use specialized materials designed to develop practical life skills, sensory awareness, language, math, and cultural understanding.
Most Montessori programs in Ontario serve children from infancy (as young as 6 weeks) through age 6, with some extending to elementary and even middle school. The core Montessori age groups are infant/toddler (0–3 years), primary/preschool (3–6 years), and lower elementary (6–9 years).
Montessori school tuition in Ontario typically ranges from $800 to $2,000+ per month for full-time enrollment, depending on the child's age and the program. Infant and toddler programs tend to cost more due to smaller group sizes. Some Montessori schools offer financial aid, sliding scale fees, or sibling discounts.
When selecting a montessori daycare in Ontario, consider:
  • Visit the facility in person to observe the environment
  • Ask about teacher qualifications and experience
  • Check licensing status with California's regulatory agency

  • Read parent reviews for firsthand experiences
  • Compare staff-to-child ratios across facilities
