why is the cbd found in the centre of the city
Central business district A central business district (CBD) is the commercial and business centre of a city. In larger cities, it is often synonymous with the city's "financial district". Geographically, it often coincides with the "city centre" or "downtown", but the two concepts are separate: many cities have a central business district located away from its commercial or cultural city centre or downtown.
Saint Catherine Street Saint Catherine Street (officially in French: rue Sainte-Catherine) (11.5 km or 7.1 mi) is the primary commercial artery of Downtown Montreal, Quebec, Canada. It crosses the central business district from west to east, beginning at the corner of Claremont Avenue and de Maisonneuve Boulevard in the city of Westmount, traversing the borough of Ville-Marie, and ending on Notre-Dame Street just east of Viau Street in the borough of Mercier–Hochelaga-Maisonneuve.
