Editor's note: The following information is from the Innisfil Historical Society.
Knock School's original frame structure was built in 1871 on a quarter acre for the sum of $230 at the southeast corner of Line 9 and 10 Sideroad, just south of Barrie.
The first teacher’s salary was $125 per year. By 1901, the schoolyard had been increased to one acre.
The present building was constructed in 1902 for $1,475.
In about 1921, two acres were acquired for the purpose of creating a baseball diamond.
The school was the last one-room school site in Innisfil that had not been converted to a family dwelling. The well-maintained building was basically in as-built condition, except for the addition of indoor plumbing, electricity and a furnace.
The Knock community purchased the school from the board when it was closed in the mid-1960s. It was then used as a community centre, and the ball diamond by Innisfil Minor Baseball.
Since 1972, the Innisfil Historical Society has used the school for regular meetings and for storage of their numerous historical documents.
In September 2002, community representatives made a presentation to council requesting this site be incorporated into the town’s parks and recreation department and that it be designated under the Heritage Act.
