The community is located in Dundas Parish, on the north-east shoreline of the Shediac Bay. Grand-Digue is located around the intersection of Grand Digue Rd and Route 530.
Following the expulsion of the Acadians in 1755, many Acadians found refuge in Grande-Digue. They did not receive land grants until 1791.[2]
The community is predominantly Acadian, and Acadian French is the most widely spoken language. However, due to the large number of summer tourists and cottagers, English is also spoken by virtually the entire population.
