Extra and Co-Curricular Activities

A student's participation in any extra-curricular activity is at the discretion of the administration. Students who participate in extra-curricular activities must represent the values of Archbishop Denis O'Connor Catholic High School. Our students must show exemplary behaviour and respect for all persons or property at school or any other location where they represent the school.


All secondary school sports at the Durham Catholic District School Board are governed by the Lake Ontario Secondary School Athletics (LOSSA) and the Ontario Federation of School Athletic Associations (OFSAA). LOSSA and OFSAA are non-profit organizations that are responsible for the rules and regulations of all high school sports in Durham Region and Ontario.

To access information for specific sports, visit the LOSSA and OFSAA websites.
