School boards

Former school districts

There were a number of schools governed by "school authorities," which managed schools in remote and sparsely populated regions. Effective September 1, 2009, 20 isolated school authorities were amalgamated with district school boards. Prior to 1998, Ontario had 124 school districts within the province including the list above.

School sections

From 1846 to the late 1800s schools were assigned to school districts or school sections. Instead of names for each school, they were assigned numbers, e.g. SS No 11.
