Corunna Site
Corunna, Ontario, Canada

Corunna Site 
Located in Sarnia-Lambton's Chemical Valley, about
180 miles (288 kilometers) southwest of Toronto, NOVA Chemicals' Corunna site is a petrochemical complex that
produces 1.8 billion pounds of ethylene and up to 700 
million pounds of co-products annually.
The Corunna facility started up in late 1977 and was purchased by NOVA Chemicals in 1988. It was the first fully integrated refinery and petrochemical complex in North America. Its original processing capability was entirely crude-oil based feedstock. Through the years the facility has been upgraded and beginning in 2014 is able to process up to 100% NGLs.  The primary feedstock is ethane, with lesser amounts of propane and butane.  The facility can also utilize smaller amounts of light naphtha if economically viable.


The Corunna site's feedstock is delivered to the site by pipeline and railcar. These products are the raw materials used to manufacture primarily ethylene, but also propylene, butadiene, benzene and other co-products.

End Products

The ethylene produced is shipped via pipeline to NOVA Chemicals' Moore and St. Clair River sites for conversions into polyethylene and to other third-party customers.
Approximately 495 employees work at the Corunna plant. The facility is ISO 9001:2000 registered.
