Erinsville

Erinsville (44°29′00″N 77°03′00″W) is located on Highway 41. It was founded by Irish settlers in the late 1800s^{[citation needed]}. It is close to Beaver Lake (actually two lakes, Beaver Lake North and South) and is host to several small cottage communities. The Erinsville area is also surrounded by several family-operated farms. Largely due to its low population, Erinsville has only a few commercial business in operation. These include the Beaver Lake Variety and Gas Bar and the Lakeview Tavern and Restaurant. Several residents also run small businesses from home. Erinsville also is the site of the Church of the Assumption of the Blessed Virgin Mary, a Roman Catholic parish. Erinsville also had a train track, but it is now out of commission; a dark sky viewing area is located minutes north of Erinsville on highway 41.^[4]

Newburgh

Newburgh (44°19′30″N 76°52′40″W), formerly an incorporated village, retains the status of a designated place in the Canadian census data. It is situated on the Napanee River, and was first founded in 1822 by Benjamin Files and Wm. V. P. Detlor. It quickly became a thriving community and home to numerous mills. Two saw mills were first built along the river in 1822 and 1825, followed by a grist mill in 1828, two flour mills in 1840, an oatmeal mill in 1861, two carding mills and a woollen mill in 1864. Other businesses such as a tannery, two axe factories, a sash, blind and door factory, a hub and rake factory, three carriage and wagon shops and two cabinet factories were also established.

By 1865, Newburgh had a population of 11,200, but that population quickly declined. Railway lines bypassed the village and manufacturers were unable to move goods efficiently to and from Newburgh. The village did not get the Napanee, Tamworth and Quebec Railway line until 1884. Also, contributing to this decline were several major fires, the worst which happened in 1887 and destroyed eighty-four buildings in the centre of the village.

Today Newburgh has a clinic (Newburgh Clinic) run by two doctors, Newburgh Public School and Newburgh Post Office, Newburgh United Church, Newburgh Pharmacy, Newburgh L.C.B.O., a small grocery store and a gas station, Newburgh Abram's Bakery, Second Time Treasures by Louise, Clarke Art and Projects art gallery, and Rogues' Hollow Antiques, Ontario's two largest chicken farms, and other small businesses such as barber shops and hair salons. Newburgh also held an art show from 2004-2019 Art Among The Ruins'.

In the Canada 2011 Census, Newburgh had a population of 696, down from 725 in the 2006 census.^[5]
