In the 1960s, Dieppe underwent a major commercial shift with the construction of the Simpson-Sears store on the marsh. Today, CF Champlain, with over 160 stores and 35,000 daily visitors, is one of the largest retail concentrations in Eastern Canada. This development paved the way for the sector's continued growth. The Dieppe Boulevard area has become a key attraction for businesses, solidifying its role as a strategic hub for commercial activity in the region, especially with the continuous establishment of new businesses in the business park.
