EQAO acknowledges the enduring presence of Indigenous peoples on the lands on which we gather today across Ontario, and we thank the past, present and future caretakers of this land.
These lands are gathering points where age-old ceremonies of celebration, initiation and renewal took place. EQAO is grateful to have the opportunity to work and learn on these lands in a community of sharing.
