Pinsent's Arm is located on the south side of St. Michael's Bay, about 20 km. Southeast of Charlottetown. Settled year round since the late 1950's, the name of the community still did not appear on some maps up to 1992. In 1996 the population of Pinsent's Arm was recorded to be 11.

This community has traditionally relied on the community of Charlottetown for many services and even more now since receiving a road connection to the community. The services include schooling, health and postal services. The community of Pinsent's Arm had historically served as the winter home for summer fishing communities of Square Island, Triangle and other stations at the mouth of St. Michael's Bay. There is currently a population of 55 with surnamed such as Burden, Campbell, Clarke, Morris, Parr, Snow, Williams, Martin, Stokes and Cadwell. The Labrador Fishermen's Union Shrimp Company operates a fishing plant which enables the community to be self sufficient by producing whelks and scallops with snow crab being offloaded at the dock. It is well worth your time to drive the 24 kms. From Charlottetown to this beautiful little village which boasts of one retail store and a community hall where all the local activity takes place.
