Irving Oil is an international refining and marketing company with a history of long-term partnerships and relationships. Founded in 1924, Irving Oil operates Canada's largest refinery in Saint John, New Brunswick, along with more than 900 gas stations and a network of distribution terminals spanning Eastern Canada and New England. It also operates Ireland's only refinery, located in the village of Whitegate. In 2019, Irving Oil expanded its presence in Ireland by acquiring Top Oil, a leading supplier of home heating oil, petrol and diesel fuel. Irving Oil established its European operations in 2014 with an office in London, England, and tankage in Amsterdam. Customers appreciate Irving Oil's gas stations, which are often a few cents cheaper than competitors. The stations feature mid-sized convenience stores stocked with magazines, snacks, drinks, ice cream, lottery tickets, cigarettes, and a small New Hampshire gift area. Many locations also have a Dunkin' Donuts with a drive-thru. Reviewers describe the bathrooms as large and usually clean, making the stations a popular stop for travelers.
