Durham County was created in 1792 by a proclamation of Lieutenant Governor Simcoe. The original boundaries were as follows:
That the thirteenth of the said counties be hereafter called by the name of the county of Durham ; which county is to be bounded on the east by the westernmost line of the county of Northumberland, on the south by lake Ontario until it meets the westernmost point of Long Beach, thence by a line running north sixteen degrees west until it intersects the southern boundary of a tract of land belonging to the Mississague Indians, thence along the said tract parallel to lake Ontario until it meets the northwesternmost boundary of the county of Northumberland.[1]
In 1798, the Parliament of Upper Canada passed a statute defining the boundaries of the counties. Durham was then defined to include:
That the townships of Hope, Clarke and Darlington, with all the tract of land hereafter to be laid out into townships, which lies to the southward of the small lakes above the Rice Lake, and the communication between them and between the eastern boundary of the township of Hope, and the western boundary of the township of Darlington, produced north, sixteen degrees west, until they intersect either of the said lakes, or the communication between them, shall constitute and form the County of Durham.[2]
In 1834, the townships of Verulam, Fenelon and Eldon were added to Durham County.[3]
The townships of Darlington and Clarke were amalgamated with the Town of Bowmanville and the Village of Newcastle as the Town of Newcastle, and the township of Cartwright was combined with the Ontario County townships of Scugog and Reach to create a new Township of Scugog. In 1993, Newcastle was renamed Clarington.
