Lauremont School, formerly Toronto Montessori Schools, is one of the oldest Montessori schools in Canada. Founded by Helma Trass in 1961, it still remains the most well-known Montessori and IB school in Ontario. The school moved to Richmond Hill from Toronto in 1964. The school's Bayview Campus (18 months to Grade 6 students) and the Elgin Mills Campus (Grades 7 to 12) are located in Richmond Hill, Ontario, Canada. The Head of School is currently Mr. Andrew Cross. The school's first location was in Toronto, which is why, despite being located now in Richmond Hill, it maintained its name 'Toronto Montessori Schools' until the rebranding in 2024.

Toronto Montessori Institute opened in 1971 at Victoria College, University of Toronto and relocated to Richmond Hill in 1980. TMI has closed as of June 30, 2022.

Also located at the Lower School address is the Toronto Montessori Institute (TMI), founded in 1971 and one of the oldest teacher training Montessori schools in Canada.

TMS School remains a flagship Montessori school (18 months to Grade 6) and IB world school (Grades 7 to 12) and has been internationally recognized since 1961.

TMS has announced in May 2023 its intention to change its name to "Lauremont Schools" in September of the 2024-2025 school year. The "Laure" part of the new name stands for Baccalaureate, and "mont" for Montessori .

In Grade 7, when students enter the upper school at TMS School, they are assigned to one of four Houses. The mission of the House System is to unify students into proud families that will be challenged and entertained, fostering the spirit of the student body. The four Houses are named after mythological titans, echoing the school theme of Titans:

• Atlas
• Helios
• Phoebe
• Tethys

Students take part in activities with their Houses that are designed to promote friendly competition amongst the Houses involving all branches of the four pillars (academics, arts, athletics, and citizenship) including general spirit. House points are recorded throughout the year and the House with the greatest total is awarded the House Cup at the end of the year.

Each House has two elected House Captains.
