On May 8, 2008, Irving announced that they would lease 252 of its gas stations in Atlantic Canada and New England to Couche-Tard for 20 years. Their gas remain supplied by Irving, but their convenience stores were converted to Circle K. In 2018, following Couche-Tard's acquisition of CST Brands (which saw most of its Canadian assets sold to Parkland Fuel), 36 Ultramar stations in Atlantic Canada were put into teams - 23 were rebranded under the Irving Oil brand and 13 were sold to Irving outright (and rebranded to Irving/Circle K) under a similar agreement to the other locations.
