The Quebec-based corner store mammoth Alimentation Couche-Tard (Power Night Owl) will phase out the name Mac’s and replace it in Canada with the U.S. brand name Circle K. This will begin in 2017 according to a news release from the Laval headquarters of the firm Tuesday. Circle K is already Couche-Tard’s most widely used store banner, primarily in the United States plus 12 other countries. The announcement was made ahead of Couche-Tard’s annual meeting for shareholders.
