Major company holdings: Alimentation Couche-Tard
Alain Bouchard’s transformation of Alimentation Couche-Tard from a single convenience store into a $35-billion retail empire is one of the country’s more successful business stories of the past 40 years. With the synergies flowing from its consolidation of its various brands under the Circle K moniker, and the company’s US$3.8-billion acquisition of Texas gas and convenience store chain CST Brands Inc. last summer, it looks set to extend its growth streak.
