Fitzroy Township's first school was a log building that was established in Fitzroy Harbour in 1832 by Charles Shirreff. That building also served as an interdenominational church and hall. Fitzroy Township boasted seven log schoolhouses by 1847.

When Mohr's Corners Secondary School Number 6 was constructed in 1885, it was the second school established in the township. Erected by Mr. Forbes on the Sixth Line, the school had an attendance of about 50 children in its earliest years. Miss Clarke was the first teacher.

Mohrs Corners was a prosperous little centre by 1863, and its small school experienced a growth in attendance until the 80 pupils who were packed into the building became too many for comfort.

A new brick school, one of the few buildings to be constructed of brick in those early days, brought pride to residents when it was built in 1868. It cost $800 to build and the land was purchased from Archibald Riddell. He, William Hunt and William Forbes were the school board members at its inception.

Three male teachers kept the classroom in order during those early years: Mr. Elliott, Richard Foster (a native of the section) and Robert Wilson (from Glasgow. Scotland). The latter held special bookkeeping classes, drawing attendance from over the township because many residents wanted to equip themselves for a place in the business world.

Many children walked through the doorway of the sturdy schoolhouse over the years. Upgrading to the facility took place in 1903 with the purchase of property from Charles Mohr for a school garden. A library was installed in the school in 1906.

Attendance swelled to 125 or more from 1915 to 1919, and two more teachers were engaged in 1920. In addition, the Township Hall at Mohrs Corners was converted to a Junior room. A third school was opened at Kingdon Mine, which was then contributing to a general wave of prosperity in the area.

With the closure of Kingdon Mines in 1931 came a large decline in the local population. The resulting decrease in the school-age population and declining local economy eventually led to the closing of the Kingdon school and Mohr's Corners Secondary School No. 6. That property was sold and it was converted into a private residence.
