The Corunna Site was North America's first fully integrated cracker and petrochemical complex when it began operations in 1977. NOVA Chemicals purchased the facility in 1988. The site has undergone continuous evolution from an oil-based naphtha cracker to a modern, low-emission ethane cracker optimized for shale gas feedstocks.​

The Corunna Site is NOVA Chemicals' largest facility in the Sarnia-Lambton region and serves as the petrochemical hub for Ontario operations, producing 1.8 billion pounds of ethylene annually.
