Upper Canada District School Board
The Upper Canada District School Board is one of the largest public school boards in Ontario in terms of geographical area. It encompasses the counties in the easternmost portion of the province, including the cities of Brockville, Clarence-Rockland, Carleton Place, Cornwall, and Akwesasne. It covers most of the area surrounding - but not including - the city of Ottawa. Trustee elections are held periodically to elect new trustees.
The board manages a main office in Brockville and four regional education centres, and offers alternate and continuing education at over 30 locations. The board foresees an overall decline in student enrolment over the next 15 years, and has engaged in long-term strategic planning to address this issue.
