Petrolia Discovery

Visit Petrolia Discovery and experience the Fitzgerald Rig. This mechanical marvel is still the largest pumping rig in the world, operating continuously for over a century. Initially powered by steam, it later used an internal combustion engine and, finally, an electric motor. The rig takes its name from the man who erected it – Frederick Ardell Fitzgerald – Imperial Oil’s first president.
