Over time, the catalogue became a less profitable operation, and by the 1970s, it was a money-losing proposition. As Canada's population became more urban over the course of the 20th century, Canadians had access to a greater number of local stores, and were less reliant on catalogue purchases. By the mid-1970s, it was estimated that 60% of the suburban customers throughout Canada lived within a thirty-minute drive of an Eaton's store. Others blamed Eaton's management for the catalogue's failures, pointing to the similar Simpsons-Sears catalogue (later the Sears Canada catalogue), which continued until a much later date even though it never enjoyed the iconic status or popularity of the Eaton's catalogue.
