About CIS Ontario


Welcome to CIS Ontario (the Conference of Independent Schools of Ontario), your one-stop network for supporting leadership and excellence in independent school education.

If you’re a faculty or staff member at one of our 47 member schools, you’ll find the inspiration and information you need to pursue your next innovative professional-learning opportunity. You are also a member of our networking and collaboration platform, CISO Connect.

We invite you to explore our extraordinary range of student programs. More than 28,000 students province-wide have the opportunity to benefit from the music, drama, visual arts and dance festivals we provide annually to our girls’, boys’ and co-ed member schools.

And on the athletics front, more than 1,400 sports teams operate within the Conference of Independent Schools of Ontario Athletic Association (CISAA), far above the provincial average.


  • Our 47 member schools have founding dates ranging from 1829 to 2002.
  • We advocate for quality independent-school education for 28,000+ students and offer collaboration opportunities for more than 5,000 employees.
  • CIS Ontario was incorporated in 1983, replacing and building upon two more informal networks of independent schools, with a new association designed to serve twenty-three member schools within the province.  
  • We are closely affiliated with the Canadian Accredited Independent Schools, the national association that accredits the majority of our schools. We are also members of the National Association of Independent Schools (U.S.) and the Independent Schools Association Network (U.S.). In addition, we liaise with the Ontario Ministry of Education and The Ontario College of Teachers on behalf of our member schools.
