Kemptville is a community located in the Municipality of North Grenville in Eastern Ontario, Canada in the northernmost part of the United Counties of Leeds and Grenville. It is located approximately 56km (35miles) south of the downtown core of Ottawa and 2.5kmto3kmkm (01.6milesto02mileskm) south of the Rideau River.
The community can be accessed by Highway 416, also known as the Veterans Memorial Highway, which was completed in 1999, and from Leeds and Grenville Road 43 (formerly Highway 43).
Kemptville is the largest community in North Grenville, with about 69% of North Grenville's population.[1] Three elementary schools are located in the town - Holy Cross Catholic School, Kemptville Public School and South Branch Elementary School - two high schools - North Grenville District High School and St. Michael Catholic High School - three parks, and two hotels. The residential area is generally located in the south and east parts of the community. The main streets are Rideau, Prescott, Clothier and Van Buren streets. A creek named Kemptville Creek divides Kemptville in the southeast, where the least part of Kemptville is found. The creek begins southwest of Kemptville and empties 4km (02miles) NE into the Rideau River. Much of Kemptville is forested, especially east and north of the community. Farmland covers the rest of the area, especially the west and the southern part of the community, with some exceptions. There are some homes lying next to the farmland.
The small town of Kemptville began to emerge from the forest in the township of Oxford when Lyman Clothier, a resident of New England, bought of land in Concession 3 of Oxford-on-Rideau Township from a John Byce in 1819 for C£75. Mr. Clothier began construction of a saw mill with the assistance of his four sons, and they built two dwellings in what is now Kemptville. This mill was extremely important for the settling of the community, as in order to construct a crude dwelling, lumber was required - and so, the mill began to facilitate the construction of dwellings for settlers all over Oxford Township.
The Clothiers placed some grinding stones in the lower part of their saw mill. As a result of this, rather than taking their grain to a site on the Saint Lawrence River, which would be a daunting hike in the best of conditions, or grinding the grain in an extremely ineffective and crude fashion, the settlers could now take it to this grist mill. After this was established, a blacksmith's shop was established, run also by the Clothiers. A schoolhouse was established in 1823, which served the surrounding communities for many years. The first physician arrived in the community the year after the school was established.
The small village was expanding quickly and the residents of the region were beginning to think about officially giving a dignified name to the location in which they lived. Initially, the community was known as "Clothier's Mill". So, during a public meeting at this time, the name "Kemptville" was suggested, to honour Sir James Kempt, the Governor of Upper Canada in 1829, who was said to have camped on the banks of the Rideau River near the settlement. The name was adopted in 1829 and the first map with the name "Kemptville" was produced in 1830.[2] The post office was established in 1831.[3]
The Kemptville 73's are a Tier II Junior "A" hockey team and members of the Central Canada Hockey League. The team was founded as the Kemptville Comets of the Rideau-St. Lawrence Junior B Hockey League in 1969, but the league later became the Eastern Ontario Junior B Hockey League and the Comets became the 73's in 1973. The 73's were promoted to Junior "A" in the Summer of 2007.
Birthplace of 1930s NHL player Desse (Desmond) Roche.
