2. What do you do differently and uniquely well?

Inquiry-based learning is at the heart of our teaching approach. Students are expected to review materials independently, and class time is used for discussion, experimentation, and problem-solving. Teachers closely monitor each student’s progress, offering extra challenges to those who want to go further and additional support to those who need it. With small class sizes, teachers truly understand each learner’s pace, strengths, and interests, ensuring no one is left behind. In our Early Learning & Elementary programs, this approach comes to life through projects that invite students to test ideas and learn by doing. Students collaborate to design spaghetti structures, experiment with movement and mechanics through hydraulic models, and express French and language understanding through art, drama, and hands-on challenges. By combining structured learning with exploration, teachers create classrooms where curiosity leads learning and every student can engage.

3. What tradeoffs has your school made to serve families in this way?

Our approach is based on the timeless values of security and discipline. While some students may initially find challenging to adapt to the structure we provide, this process is key to building resilience and character. In today's fast-paced world, we believe in maintaining a supportive, disciplined environment that helps students grow, bounce back from failure and graduate successfully as accountable and responsible individuals. The balance between traditional and innovative methods ensures that every student is not only prepared for academics success but also equipped with the life skills and values needed to thrive as global citizens. The journey may start with challenges, but the long-term rewards of personal growth, confidence, and a strong moral foundation are invaluable.

4. What key junctures in your school's history have most shaped its present?

J. Addison School was founded in 2002 to provide high-quality education for international students, inspired by a vision to raise the standards of private schooling. By 2004, our enrollment had grown to over 100 full-time students, prompting a move to larger facilities in Scarborough. Shortly after, we opened our boys’ and girls’ residences to accommodate our growing community.

In February 2005, to meet increasing demand, we acquired 3 acres of land in Markham to construct a state-of-the-art 60,000-square-foot campus designed with students' needs and security in mind. The new campus opened in September 2007.

On our 15th anniversary, we began a partnership with York University, offering enhanced opportunities for our students. This commitment continued with a collaboration with Wilfrid Laurier University in 2023, Metropolitan Toronto University in 2024, and Trent University in 2025, broadening pathways for our graduates and reinforcing our dedication to excellence in education.

5. What type of student is a good fit for your school?

We seek for families that valued the importance of discipline, and good habits, committed to develop well-rounded individuals who will positively impact their community. We push our students to their highest level of ability that is why we care about families that believe in team-work between parents, students and school to support and guide younger generations through the development of character and civic responsibility as the foundation to navigate today's fast-paced digital world.

6. Under what conditions would you advise a family against choosing your school?

J. Addison School may not be the ideal fit for every family, as our approach and environment cater to specific educational values and goals. Our emphasis on structure and balanced approach may not fit families looking for a highly specialized curriculum. While we celebrate diversity and global perspectives, with 50% international students, some families might seek a more homogeneous school environment.

7. To your knowledge, why do families choose your school over others?

Many families choose J. Addison School because of the sense of safety, support, and personal attention we offer. Our 24/7 on-campus security and boarding supervision give families peace of mind, while our close-knit environment allows students to feel seen, heard, and supported every day. Students know all their teachers and staff by name, creating a welcoming space where they feel comfortable asking for help. This strong connection fosters confidence, encourages open communication, and helps children grow not only academically but also socially. The combination of structure, care, and trust sets our school apart as a place where students and parents feel safe an engaged.

8. How would you characterize your school's image amongst the public?

At J. Addison School, our reputation is built on strong academic standards, respect for tradition, and values that families have trusted for generations. We are well known for three defining strengths. First, our students are consistently recognized for their manners, discipline, and respectful behavior at every academic, athletic, and community event they attend—reflecting the importance we place on character and personal responsibility. Second, our graduates achieve a 100% acceptance rate into top universities and colleges, a result of a rigorous academic curriculum combined with highly personalized guidance counselling that supports each student’s pathway. Third, our Elite Basketball Program is recognized for developing outstanding student-athletes who gain international exposure and often earn scholarships at universities and colleges across Canada and the United States. Together, these pillars define a school culture where excellence, respect, and long-term success go hand in hand

9. What aspect of your school is underappreciated?

One aspect of J. Addison School that is often underappreciated is the powerful impact of our international diversity—not just among students, but also within our staff. With students from over 20 countries and a team of educators and support staff who speak more than six languages and come from a variety of cultural backgrounds, our school is a vibrant, global community. While some may see being mostly international as a challenge, it is actually one of our greatest strengths. This diversity fosters an environment where both local and international students develop global awareness, empathy, and strong social skills. At J. Addison, students and staff alike grow together, learning from each other and building the mindset and confidence needed to thrive as global citizens.

10. What might families find surprising about your school?

Families may find how incredibly diverse our school really is. It is true that many of our students are international students but they are from a variety of different countries. Many of our local students have the opportunity to interact and learn from our international students and vice versa. Families often overlook the fact that students learn from each other.

11. What improvements or changes has your school made recently?

Following our mission on developing well-rounded individuals we have joined to The York Region Athletics Association. Our goal is to strengthen life skills such as perseverance, resilience, collaboration and leadership. We now have competitive Volleyball, Basketball, Badminton, Soccer and Track and Field teams as alternatives apart from our Elite Basketball Program.

We also started collaborations with Wilfrid Laurier University in 2023, Metropolitan Toronto University in 2024, and Trent University in 2025 broadening pathways for our graduates and reinforcing our dedication to excellence in education.

12. How will your school change in the next 5 years?

Building character, instilling kindness, and respect are all at the forefront of building the foundation to a lifelong positive journey to learning. In the next 5 years, we’ll have to embrace the leading technological forces that have reshaped how students learn. While we firmly believe that AI will never replace the human teaching experience, we also have to incorporate the advantages available to strengthen and harness teaching strategies, processes, concepts, and methodologies to encompass a mass breadth of learning styles that our children embody. We will support the next generation of leaders as they grow and learn to shape the future using technology and innovation with purpose and integrity.

Gr. 8 (current) — I am a 9th-grade student at J Addison School and I was originally born in Beijing, China. In 2021, I came to J. Addison School as an international boarding student and I have been at the school for almost a year. Within my first year at the school, I felt an immense sense of care from dormitory staff, teachers and school administration. The environment of J. Addison School is extremely clean and very tidy. I must acknowledge that the cleaning staff does a great job ensuring that my living environment is well sanitized. Additionally, I am also very satisfied with the facilities that the school offers, such as a large indoor air-conditioned gymnasium and a beautiful cafeteria that serves diverse quality meals. In addition, the school's security measures are also very good. For example, the school and dormitory are monitored 24 hours a day and there are surveillance cameras on the school property. Another aspect of my student experience at J. Addison School that I like is the medical services that are easily accessible to boarding students. For example, when I am sick, the dorm staff makes arrangements to take me to the clinic or hospital at any given date and time and provides needed support, if there is a language barrier. Above all, I really like living in the dormitory with my friends and taking part in various activities hosted by the dorm staff, such as shopping, visiting tourist attractions like Niagara Falls or going to the movies. Overall, my student experience at J Addison school is very good!

Gr. 7 (current) — From my perception, I think J. Addison school is indisputably the most outstanding private school in Toronto among other schools I’ve been to. The experience I had here at J. Addison will forever leave a lasting impression on my mind. I love mostly everything about J. Addison school, though there were some things that didn’t go well for me regarding my personal conduct, however, I am extremely grateful for the care and support provided by the faculty and staff. For the people who are planning to study at J. Addison School, my advice as a young boarder is to avoid getting into conflicts with others such as your dorm peers, faculty and staff. J. Addison School has helped me to grow as an individual this year, which I believe will help me to be a better individual and student. If there’s one thing I could change about the school would be more personal space in the dorm room that optimizes privacy.

Based on my personal experience, I would consider the school like a second home for me. In addition, there are over 300 day and boarding students from various countries, including Canada. The school offers a friendly atmosphere that can be describe as a small multi-cultural community. If there is one thing that I would improve about my student experience at J. Addison School is the opportunity to meet other students from different grade levels during the school day as the current pandemic has slightly restricted the student movement for our health and safety. Despite this challenge, the relationships between faculty and students are respectful. The faculty are truly nice and they display a high level of patience when helping students understand the content area of a specified subject.

My experience at J. Addison School has truly been good. My grade 8 teacher, Ms. Perry is an outstanding educator that is extremely helpful. She makes learning fun by giving us engaging assignments and offers opportunities for us to relax. Our classrooms are clean, well-organized and offers the ability for students to connect to the school's "Wi-Fi" network. The interior design of the classroom is quite interesting that makes an exciting learning environment. The school's cafeteria is also beautiful, as it displays various international flags that represents the diverse student population. Equally as important, the food is quite divine. Some of my favorite meals are, fried rice, fries, grilled chicken and steak. If there is something that I would consider as a positive change at J. Addison School, would be to continuously expand the technological network within our school community as they are currently doing.

Student, Sohaila Mohammed (2021)

At J. Addison School, the student population and staff are made up of various nationalities, which I love! Being an international student from Egypt, I thought this aspect was truly important, as I felt a sense of belonging. The school leadership and management is truly cooperative as well. I feel like I can visit the principal at any time throughout the day to have a conversation with him about any issue that I may have. Finally, I love the school policies to ensure the safety and well-being of the school community, especially during the current pandemic, where everyone is extremely worried about Covid-19 in Canada. The school provided assurance and ease that we will be safe and provided on-going support to any concern that we may have.

Student, Natalija Sekulovska (2021)

I am a student from Europe that is currently attending J. Addison School, who never had a study abroad experience until now. Before my arrival at J. Addison School, I felt a sense of ease because the staff and principal explained everything to me about the school, expectations and transitioning to boarding life. What I like about the school is the fact that the school is multicultural, which gives me the opportunity to learn different languages and cultures. In addition, the students are very polite and helpful as well as the staff. The teachers are very patient with you and take their time to explain everything to you. From personal opinion, I can't think of anything that I would like to change as everything is available for me.

Student, Zhi Ye Cao (2021)

My student experience at J. Addison School has been wonderful. Personally, I love the atmosphere of the school and the dorm, as it provides a warm and welcoming feeling as a boarding student. In addition, I love the faculty and dorm staff as they are extremely helpful and kind. Moreover, the location of the school is not remote, as there are shopping malls, grocery stores, restaurants, medical and dental clinics that are all situated around the school. Furthermore, I feel safe attending the school as safety and security is a major priority for the school. Another factor that I like about the school is the food. The on-site cooking staff prepares delicious and well-balanced meals for us. In my opinion, if there is one thing that I would change about the school would be nothing, as I feel that they truly care about the student experience and work diligently to provide the best support for myself and for other students.
