Corunna, Ontario, Canada

Corunna Site 
Located in Corunna, Ontario and situated about 180 miles (288 kilometers) west of Toronto, NOVA Chemicals’ Corunna Site is a petrochemical facility that can produce 1.8 billion pounds of ethylene and up to 700 million pounds of co-products annually. It began operations in late 1977 and was purchased by NOVA Chemicals in 1988. It was the first fully integrated cracker and petrochemical complex in North America.


The Corunna site's feedstock is delivered to the site by pipeline and railcar then thermally cracked 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 500 employees work at the Corunna plant.
