Downtown St. John’s serves as the hub of the local oil & gas industry. Many oil & gas companies, both producers (those which actually recover oil & gas) and supply and service companies (those which provide services and complete tasks necessary to make oil & gas recovery possible – such as engineering, construction, fabrication, transportation, customs, recruitment, etc.) choose to locate their headquarters and offices in downtown St. John’s. As a result, many onshore positions in the local oil & gas industry are located in office buildings in the downtown area of the capital city.
