Irving Oil is a well-established company with a long history dating back to 1924. It operates Canada's largest refinery in Saint John, New Brunswick, and Ireland’s only refinery in Whitegate. The company has a vast network of over 900 gas stations and distribution terminals across Eastern Canada and New England. In 2019, Irving Oil expanded into Ireland by acquiring Top Oil, a leading supplier of home heating oil, petrol, and diesel. Their European operations began in 2014 with an office in London and tankage in Amsterdam. Customers appreciate Irving Oil for its clean facilities, friendly staff, and good gas prices. The gas stations often have cheap fountain sodas and a variety of convenience items. The stations tend to be busier during morning hours, and some pumps are available for after-hour use, indicating a reliable and popular service.
