Offering a variety of programs for learners across Burlington, Halton Hills, Milton and Oakville, including secondary credits, youth programs, academic upgrading and language programs.
New to Canada?
Welcome to Halton! We’re here to help students and families new to Canada by offering information on education, health care, employment services, and housing. Translation services are also available.
Halton Catholic Children's Foundation
The Halton Catholic Children’s Foundation (HCCF) is an independent charity. The goal of the foundation is to help HCDSB families in need overcome financial barriers to learning, which helps those students succeed in school.
Mental Health & Well-Being
The health and well-being of all students is our highest priority. Our Catholic values instill a strong belief to care for one another and ensure that our schools are safe, engaging, welcoming and inclusive places to learn.
Indigenous Education
HCDSB is committed to providing equitable, inclusive, and engaging educational opportunities for all students. As part of this commitment, HCDSB acknowledges the significant contributions of Indigenous communities and the importance of embedding First Nation, Métis and Inuit history, culture and perspectives in the curriculum taught in our Catholic Schools.
Special Education at HCDSB
We believe that each student is a unique gift from God and as such has the right to an education which will foster spiritual, intellectual, physical, emotional, and social growth. We believe that students with special needs (exceptionalities) should be given the opportunities and support necessary to reach their full potential.
