Saint John is a seaport city of the Atlantic Ocean located on the Bay of Fundy in the province of New Brunswick, Canada. Saint John is the oldest incorporated city in Canada, established by royal charter on May 18, 1785, during the reign of King George III. The port is Canada's third largest port by tonnage with a cargo base that includes dry and liquid bulk, break bulk, containers, and cruise. The city was the most populous in New Brunswick until the 2016 census, when it was overtaken by Moncton. It is currently the second-largest city in the province, with a population of 67,575 over an area of 315.96 km².
French colonist Samuel de Champlain landed at Saint John Harbour on June 24, 1604 and is where the Saint John River gets its name although Mi'kmaq and Wolastoqiyik peoples lived in the region for thousands of years prior calling the river Wolastoq. The Saint John area was an important area for trade and defence for Acadia during the French colonial era and Fort La Tour, in the city's harbour, was a pivotal battleground during the Acadian Civil War.
