Until 2018, Imperial Oil was a member of the rewards program Aeroplan. On March 13, 2018, Loblaw Companies announced that it had reached a deal for the Esso-branded stations to join the PC Optimum rewards program, beginning on June 1, 2018. Loblaw Companies had sold its network of 213 gas stations (all of which are attached to its various grocery store locations) to Brookfield Business Partners in 2017; Brookfield entered into an agreement with Imperial Oil to use the Mobil brand for these stations. As part of the sale agreement, these stations also continue to participate in PC Optimum.
