At the age of twenty, Murray Koffler inherited two Koffler's Drugs pharmacies, first at 376 College Street and second on Bathurst Street north of St. Clair Avenue West, then opened a suburban location at Don Mills Centre on the advice of E.P. Taylor. By 1962, Koffler's had grown to a chain of 17 pharmacies, which he renamed "Shoppers Drug Mart" in the 1970s. The first store named "Shoppers Drug Mart" was at Shoppers World Danforth from which it derived the name.
