Aultsville, Ontario, was first settled in the late 1700s by a small group of five disbanded soldiers of the King's Royal Regiment of New York; these men were Loyalists who likely acquired the land here via grants for their loyalty to the Crown.
Upon its initial settlement, the Loyalists called the settlement Charlesville, the origin of this name is unknown.
Shortly after, the village became referred to as Aultsville after Samuel Ault, a relative of one of the first five men to settle here and a prominent political figure.
The Ault family dammed the creek upon their arrival and established a saw mill on their property; the village essentially grew around this mill.

The first store and tavern were present in the village in the 1700s, established in 1787 by a Loyalist settler named Richard Loucks.
The tavern was referred to as Loucks tavern, and was a large wooden building.
The tavern doubled as a courthouse and village jail, with a pillory located inside for locking up criminals.

By the end of the 18th century, Aultsville had already established its own post office with the first post master listed as one John Bockus.
The post office remained in operation until 1957, when it closed for the flooding of the Seaway.
