18th and 19th centuries The
Miꞌkmaq name for the area around where Sheet Harbour is today was
Weijooik, which translates to "flowing wildly". Almost all of the present land area of Sheet Harbour was granted in 1773, and the settlement was established around 1784, by
Loyalist refugees and
British veterans of the
American Revolution and became a prosperous centre for the
lumber industry. Sheet Harbour was named "Port North" on the Royal Navy Chart that was published in 1778. In January 1805, the ship Salisbury was wrecked off of Sheet Harbour and nine of the crew were lost. The settlement was referred to as Port North until 1807. Alternate names for the settlement were Campbelltown and Manchester. It remained in operation until it was destroyed by
Hurricane Beth in August 1971. The first electrical lines were run into Sheet Harbour in the fall of 1925. The first line ran along the shore and was an offshoot of the line that ran to the mill, which received its power from the Ruth Falls power plant along East River. A second line was built in 1928 along the west side of the highway to provide street lighting. A lighting ceremony was held after all of the houses in the community had been wired. They were an early adopter of hydro electric power, and produced 23,000,000 kilowatt-hours per year in the early days. The first efforts were made to establish a hospital in Sheet Harbour in the spring of 1945. The effort was sparked by
Duncan MacMillan, a doctor who had been serving the Sheet Harbour area for about 20 years at the time. A meeting was held in early 1946 at the Masonic Hall in Sheet Harbour. Representatives of the Nova Scotia branch of the Canadian Red Cross were in attendance. The plan was given unanimous approval at the meeting and steps were taken to organize an official hospital board, which was incorporated in March 1946 by the Nova Scotia Legislature. An enthusiastic funding campaign was started afterward. The hospital board then engaged an architect, Leslie R. Fairn, to design the hospital. The plans called for a 21-bed
Georgian style building. John Smiley was engaged as the contractor for the project, and was later succeeded by Robert MacDonald. Construction began in 1947. The total cost of construction was $170,000, with $34,000 contributed by the provincial and federal governments, while the remaining $136,000 was contributed by the residents of the Sheet Harbour area. The Eastern Shore Memorial Hospital was opened with an official ceremony on May 24, 1949, The bridge was in length, with a main span of . It spanned the Northeast Arm of Sheet Harbour, just north of the new bridge. The deck carried the two lanes of Trunk 7, and was hung from the arch by vertical steel hangers. The ribs of the bridge were reinforced heavily in 1988.
21st century Sidewalks were built through the main downtown area of Sheet Harbour in 2010. They cost approximately $2.9 million (US$2.4 million). Watts Wind Energy, Inc. built a wind turbine in
Watt Section, a small community east of Sheet Harbour. It was the outcome of favourable wind data that was obtained by a meteorological tower near the future site of the wind turbine. It was constructed in 2010 and was producing power by October 2011. It stands tall and produces about 1.5
MW of electricity, powering 375 households. A motion was put forward to the former Halifax Regional School Board in 2012 to review the schools within the Duncan MacMillan High catchment area. The review was conducted and concerns were raised about the aging facilities as well as a high transfer rate and commute time for faculty. Boundary changes were proposed – the catchment area was the largest in the board – but proved highly unpopular among the populace. The HRSB publicly announced the project to build a new
P-12 school in the Sheet Harbour area on December 23, 2013. Three sites in and around Sheet Harbour were proposed, but it was decided in 2016 to construct the facility on the then current ground of SHCS and DMHS. SHCS was closed in 2017 to provide clearance for the new structure. Lakefront Consolidated Elementary in
Tangier was closed in 2019 as a part of the consolidation process associated with the plan. The school opened in September 2020. The
East River Bridge was built from 2014 through 2015 to replace its predecessor of the same name. The
Nova Scotia Government had proposed minor repairs, but they decided that an entirely new bridge would be more cost-effective. The new bridge was designed, unlike its predecessor, without large, overhead steel arches, because it would have been twice as expensive to build. The new bridge was constructed on the same site as the old bridge's predecessor which was constructed just south of the East River Bridge in 1907. The bridge cost $19,000,000 (US$14,671,644) to build and construction began in September 2014. The contractor,
Dexter Construction, poured of concrete over of
rebar. The new bridge relies on two pillars set in the
granite below the Northeast Arm. A deck, along with railings and sidewalks, were laid when it was nearing completion. The bridge was officially opened on December 17, 2015, to pedestrians and opened the next day to traffic. Road adjustments were made on the Sheet Harbour side of the bridge to accommodate it. Trunk 7 was aligned with what was formerly Riverside Drive, Church Point Road and Pool Road were slightly modified and the access road to
Duncan MacMillan High School was slightly modified as well. Sprott Lane, a minor loop, was extended along a part of the old Trunk 7 for a few households. Shortly after the new bridge was opened, the old East River Bridge was closed and was demolished through 2016. ==Economy==
