St. John's economy is connected to both its role as the provincial capital of Newfoundland and Labrador and to the ocean. The civil service which is supported by the federal, provincial and municipal governments has been the key to the expansion of the city's labour force and to the stability of its economy, which supports a sizable retail, service and business sector. The provincial government is the largest employer in the city, followed by Memorial University. With the collapse of the fishing industry in Newfoundland and Labrador in the 1990s, the role of the ocean is now tied to what lies beneath it – oil and gas – as opposed to what swims in or travels across it. The city is the centre of the oil and gas industry in Eastern Canada and is one of 19 World Energy Cities. ExxonMobil Canada is headquartered in St. John's and companies such as Chevron, Husky Energy, Suncor Energy and Statoil have major regional operations in the city. Three major offshore oil developments, Hibernia, Terra Nova and White Rose, are in production off the coast of the city and a fourth development, Hebron, is expected to be producing oil by 2017.
