The stables were the first part of the Casa Loma Complex to be built. It was designed by E.J. Lennox, architect of Toronto's Old City Hall, and construction started in 1905. Cost of construction is estimated at $250, 000.

The stables are built of red brick with cast stone trim. The design is inspured by the Mannerist style, commonly found in stables in large European estates. The stable stalls were made of Spanish mahogany. An 800-foot tunnel running below Austin Terrace connects the stables to the main castle.

When high-taxes forced the original owner, Sir Henry Pellatt, to move out, the complex was takenover by the City of Toronto. In 1937, the Kiwanis Club of West Toronto took over the lease from the City of Toronto and opened the stables as a heritage attraction. 

During the Second World War, the stabes became a manufacturing location for a device that could detect German U-Boats. 

The stables were listed as a Heritage Propety in 1975 and designated under Part IV of the Ontairo Heritage Act in 1987.
