Students will plan and select their community involvement activities in consultation with their parents

The Provincial Literacy Requirement

All students are required to meet the secondary school literacy graduation requirement in order to earn an Ontario Secondary School Diploma (OSSD). The requirement is based on the expectations for reading and writing throughout the Ontario curriculum up to and including Grade 9.
