Mac's

Mac's, or Mac's Convenience Stores, was a Canadian convenience store chain owned by Alimentation Couche-Tard.

Updated July 27, 20261 min readCited sources

Mac's, also known as Mac's Milk, was a Canadian convenience store chain that has been largely phased out in favour of the Circle K banner.

What it is

Mac's began in 1961 as Mac's Milk in Ontario and expanded into a general convenience store chain across Canada. It sold everyday items, fuel, and prepared beverages. Alimentation Couche-Tard acquired the chain in 1999 and integrated it into its network.

Why it matters

The Mac's brand was a familiar name in Canadian retail for decades. Its rebranding to Circle K — announced in 2015 and carried out from 2017 onward — represents a major shift in Couche-Tard's Canadian operations, consolidating its stores under a single global banner.

Key details

The Mac's name is now largely historical. Former Mac's locations were converted to Circle K, and the brand no longer operates as an active national banner. Its legacy is linked to Ontario origins and a strong presence across English-speaking provinces.

In short

  • Founded in 1961 as Mac's Milk in Ontario.
  • Acquired by Alimentation Couche-Tard in 1999.
  • Rebranded to Circle K starting in 2017.
  • Brand is now retired as an active Canadian retail banner.
