The petrochemical industry is the third largest manufacturing sector in Canada in terms of value-added products and sales. The industry is a major contributor to Canada's thriving economy.
In Canada, ethylene is the primary petrochemical product made in the largest quantity from whichever feedstock is used. Alberta's plants are based almost entirely on natural gas feedstocks (methane and ethane). Ethylene is produced in Alberta, Ontario, and Quebec and used at nearby plants to make derivatives including ethylene oxide, ethylene glycol, ethylene dichloride, and vinyl chloride monomer, and polymerized to synthetic resins including polyethylene, polyvinyl chloride, polystyrene, and synthetic rubber.
One of the largest ethylene and polyethylene sites in North America is at Joffre, Alberta. The site consists of three ethylene and two polyethylene facilities. Close to three billion kilograms of ethylene and over 998 million kilograms of polyethylene are produced annually.
