NOVA Chemicals Corporation is a plastics and chemical company headquartered in Calgary, Alberta, with Executive Offices in the Pittsburgh suburb of Moon Township, Pennsylvania and Lambton County, Ontario. NOVA Chemicals' products are used in a wide variety of applications, including food and electronics packaging, industrial materials, appliances and a variety of consumer goods. The company operates two business units and holds a 50% interest in a major joint venture with INEOS Group Limited (INEOS), called INEOS NOVA.
NOVA Chemicals was founded in 1954 as Alberta Gas Trunk Lines by the Alberta government. In the 1970s, NOVA Chemicals expanded into the chemicals industry.  The company was privatized in 1961 and was renamed NOVA Corporation in 1980.   In 1998 it merged with TransCanada Pipelines Limited  and also became a publicly traded company for the first time that year. NOVA Chemicals was long headquartered in Calgary, Alberta, until then-CEO Jeffrey Lipton moved the executive offices to Pittsburgh, PA in the late 1990s. While this was move was made in order to be closer to US customers, the benefits of the move never materialized. It was also seen as a snub to the province of Alberta, as Premier Ed Stelmach refused to grant NOVA Chemicals a bailout in 2009 due to the financial meltdown and recession, as well as the company's heavy debt load. 
On July 6, 2009, the International Petroleum Investment Company (IPIC), which is wholly owned by the government of the Emirate of Abu Dhabi, completed the 100% purchase of NOVA Chemicals, and transferred its place of incorporation to the Province of New Brunswick. 
In the United States, NOVA Chemicals has focused recent expansion in the Gulf Coast area. This includes acquiring a olefins plant that produces roughly 1.95 billion pounds of ethylene annually in Geismar, Louisiana, which was purchased from Williams Partners.  The company is also considering the building of a new polyethylene plant in St. Clair Township. 
The Olefins/Polyolefins business unit produces and sells ethylene, PE resins and co-products from its two manufacturing centers located in Alberta and Ontario, Canada. The business is built on its feedstock cost advantage in Alberta, world-scale and energy-efficient manufacturing facilities and proprietary Advanced SCLAIRTECH and gas-phase polyethylene technology.
The Olefins/Polyolefins business unit contains three reporting segments:
- Joffre Olefins, which produces and sells ethylene and co-products and includes the Joffre, Alberta, site’s three ethylene crackers.
- Corunna Olefins, which produces and sells ethylene and co-products and includes the Corunna, Ontario, ethylene flexi-cracker.
- Polyethylene, which produces and sells PE and includes both the Alberta and Ontario based PE assets. In addition, the Polyethylene segment licenses its proprietary process technology and catalysts.
Performance Styrenics manufactures and sells expandable polystyrene (EPS) in North America and specialty Polymers. This business unit also has interests in EPS-based downstream ventures and businesses for end-use consumer and industrial applications.
Until September 30, 2007, NOVA Chemicals operated a commodity styrenics business unit known as STYRENIX, which manufactured and sold styrene and SPS in North America. It also manufactured and sold SPS and EPS in Europe through NOVA Innovene, its 50:50 joint venture with INEOS.
On October 1, 2007, NOVA Chemicals and INEOS expanded their European joint venture to include the North American styrene and SPS businesses of both companies. NOVA Chemicals no longer reports the results of its STYRENIX business unit but rather its interest in INEOS NOVA.
