[1][2] Launched on 1 February 2018,[3] the program allows shoppers to earn points based on specific purchases at Loblaw grocery store locations, including in-store promotions, personalized offers delivered via the PC Optimum website and mobile app, as well as per-dollar spent on eligible products at Shoppers Drug Mart, Esso and Mobil locations.

[6][7] In January 2017, an Ottawa man was arrested for fraud and money laundering for the redemption of points from stolen PC Plus accounts to purchase gift cards worth hundreds of dollars in value.

Users were instructed to transition their existing PC Plus and Optimum accounts online or do so in person and exchange their cards at Loblaw grocery or Shoppers Drug Mart locations.

[18] On March 13, 2018, Loblaw announced that Imperial Oil would switch to PC Optimum as the main loyalty program for its Esso-branded gas stations, ending a 14-year relationship with Aeroplan.

[21][22][23] In April 2019, Loblaw announced a trial program under which customers can receive free bonus points for opting into online behavioural advertising based on information associated with their PC Optimum accounts.

[24] In 2024, an investigation was launched by the Office of the Privacy Commissioner of Canada in regards to the ability to delete PC Optimum accounts.

It is possible to spend several hundred dollars in a single grocery transaction and not receive any points at all through the standard loyalty program.
