“Sunnyside” was built in 1890 for John Henry Fairbank, the oil man, banker, politician and entrepreneur. This mansion symbolizes Petrolia when it was the centre of the Canadian oil industry. The exterior was built with the rare Ohio red clay bricks which were each individually wrapped in wax paper before shipment to Petrolia. The home had 22 rooms including a billiard room, ballroom, and servant’s quarters.
