History and development

The county was established in the mid-19th century and bears the name of John Lambton, 1st Earl of Durham. Settlement and economic activity accelerated with agriculture and later with the discovery and development of oil and gas in the region. Nineteenth-century oil activity around Petrolia and nearby communities helped launch a regional petroleum industry that would shape local growth.
