Our Perspective

How we see J. Addison School

J. Addison School was founded in 2002 to serve both local and international students. The facilities are modern and extensive, including boarding and support programs designed with the needs of international students specifically in mind. The school is lead by alumni of York University, and the partnership between the institutions has grown over the years, including unique scholarships and internships. That relationship will presumably continue to grow with the completion of the York University-Markham Centre Campus. Lee Vendetti, principal at J. Addison has said, “This partnership offers all the key players in both institutions an opportunity to share expertise and resources that will make the transition to university and the working world a smoother and more meaningful experience.” The ideal student is one who will thrive in a challenging, academically oriented, international environment, and who is intending to continue to post-secondary education in Canada.

The school administration answered our questions

Who are you, as a school?

"As Canada's preeminent K-12 private day & boarding school, we take pride in nurturing tomorrow’s thinkers to becoming responsible and compassionate global citizens. Our elementary programs complement the Ontario curriculum with elements of Montessori and Pre-IB; all levels include our “Focus For Success™” adaptive program, where students learn and explore new ideas driven by interests and potential. Students are actively and continuously inspired to reach new academic heights and positive character development."

  • Grades 7 to 12
  • Entrance assessment for Grade 7 admission
  • Small class size
  • Free tutoring service
  • Advanced Placement (AP) Program
  • International exchange program
  • Extracurricular activities
  • Summer programs
  • Supervised and comfortable boarding facility

What do you do differently and uniquely well?

"Our school offers smaller class sizes with our student to teacher ratio averaging 15:1. This provides students with a better learning experience and more opportunities to improve their communication and interpersonal skills."

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

"Our school follows what we call the 7 Pillars of the Addison Advantage. We establish a positive relationship with not just our students but our parents and guardians as well through regular contact. Our school is also one of the few in the Greater Toronto Area that has a boarding program which provides students particularly those from other countries with a chance of a lifetime."

What aspect of your school is underappreciated?

"We have an excellent basketball program with a large gymnasium that often hosts basketball games with other schools. At J. Addison, we have both an elite boys and a girls basketball team. While many choose to focus on academics, many can also succeed in sports."

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."

Message from school leadership

Daniel Cooper, Principal

As I humbly and gratefully begin my tenure as Principal of J. Addison School, I can share with you that after one year in this wonderful school, I have already accumulated great memories and experiences that resonate within and provide tremendous energy, excitement and outlook toward the school year ahead.

Entering J. Addison’s 21st year, we are excited to have a very strong staff of teachers and the best overall team of quality individuals one can imagine.

Our teachers and staff are dedicated to the care of all our students, overseeing not only their academic growth but also their character development and over all well being. The students come first and this is at the forefront of our minds each day we enter the school.

We continue our commitment to developing student skills in the areas of critical thinking, creativity, technology, communication and collaboration, while supporting our students’ interests and passions. Our Focus for Success after school program, which has provided our students with academic support and extra-curricular activities over the years, continues, with all sorts of new and exciting learning and practice opportunities.

Our community is one in which every member looks for the best in one another. We do not expect perfection from our students, however our standards are very high. We know that with determination and support, every individual in this school will grow in all areas, thrive in the celebration and use of all their gifts and reach great success on this pathway to post-secondary education and beyond.

Surmounting all of this, our mission is to treat each other with kindness, thoughtfulness and compassion. With these components at the forefront – every member of this school feels secure, confident and cared for and we know that without a doubt that our students will love their experience of being a student here at J. Addison School.  It is deeply satisfying to be part of a school with such an excellent track record for success. We look forward to faithfully continuing the wonderful tradition that has been in place here for the past 20 years.
