Throughout the 20th century the fishery remained the major economic enterprise of the people of Greenspond: a bait depot was established in 1946, a fresh-fish processing plant was built in 1957 and a smokehouse was opened in the 1970s. In 1951 the town was incorporated, and with municipal government came water and sewer facilities, improved light and power services, improvements in local roads and, perhaps, the most important of all, the construction of a causeway connecting Greenspond Island with the Newfoundland mainland. In the 1990s Greenspond continues to thrive, a superb example of a Newfoundland coastal community which has survived and prospered for three hundred years despite the inherent fluctuations in a fishing economy.
