Land Acknowledgment
The ECS community acknowledges that the land on which we learn is the ancestral territory of the Kanien'kehá (Mohawk) Nation. We honor the continued presence of Indigenous peoples on this land and remain wholeheartedly committed to working towards reconciliation.
ECS is a private school for girls that offers educational services in English from Kindergarten to Pre-University (Grade 12), leading to the Secondary School Diploma (MEQ). Our Pre-University programme leads to the Ontario Secondary School Diploma (OSSD).
