Ontario Secondary School Teachers' Federation
District 13 Durham


District 13 OSSTF represents approximately 1450 permanent and 740 occasional teachers along with over 100 Professional Student Services Personnel in Durham region. Our union provides services to its members to protect them in their work and to enhance their professionalism through professional development workshops, health and safety training, collective agreement in-servicing and regular communications and public relations highlighting the teachers in our schools.

Land Acknowledgement

District 13 OSSTF is committed to providing space to honour Indigenous folks who were here on this beautiful land long before settler arrival.  We acknowledge that many Indigenous Nations have longstanding relationships, both historic and modern with the territories upon which our members work and our union operates.  We recognize the enduring presence of all First Nations, Metis and Inuit peoples throughout Turtle Island.


This region forms part of the traditional and treaty territory of the Mississaugas of Scugog Island First Nations, the Missisauga Peoples, and the treaty territory of the Chippewas of Georgina Island First Nations.  We would also like to acknowledge that prior to these treaties, the land was stewarded by various communities including the Haudenosaunee and Wendat confederacies.


Our land acknowledgement does not function as closure, resignation, or acceptance of the structural conditions of settler colonialism that remain in effect today.  We recognize the impact of colonialism and our responsibilities to redress the ways this has helped shape the education system and our organization.  We also recognize the sovereignty of all Indigenous Nations as outlined in the United Nations Declaration on the Rights of Indigenous Peoples and we are committed to honouring the Truth and Reconciliation recommendations.


To honour the Indigenous Peoples of this territory, we will take up our responsibility to be respectful of their traditions, knowledge and to care for this land and its waters for future generations.  We would like to thank all Indigenous Peoples for sharing this land so we may come together in a good way.
