COVID-19 School Closure Announcement

On March 17th,  the Ontario Government took the unprecedented step in ordering the closure of all private schools and Licensed Child Care Centres in the province as a measure to reduce the spread of the COVID-19 virus.

To ensure the safety and well being of our students, staff, families, and of the broader population, students will not return to ABC Montessori immediately following the end of March Break on March 23. ABC Montessori  will remain closed until the Ontario Government  permits schools to reopen.  We will update this message as new information becomes available. We thank you for your anticipated cooperation.

Admissions are open for the September 2020 school year

 Please call us to book a school tour. We would love to meet you.

Our Philosophy

At ABC Montessori, we believe that education is the foundation for life. The education that a child receives at an early age is one of the most important factors that will determine his or her future. The impact of early education is felt throughout a person’s life. A student’s school experience must be positive and fulfilling.

We believe the school environment must be warm and nurturing. We believe that the responsibility of ensuring a student receives a good education is shared by the school and parents. School staff and parents are partners, working together to ensure that we instill sound values, guide and inspire students to reach their full potential.
