Grenville

Grenville is a picturesque and modern municipality located on the north shore of the Ottawa River, in the regional county municipality of Argenteuil, Laurentides, Quebec. This municipality comprises between route 148 serving the shore of the Outaouais river and between Grenville Bay and the eastern end of the canal which is about downstream from the Long-Sault bridge on rue Maple, spanning the Ottawa River.

Geography
The municipality of Grenville is a village municipality crossed by route 344, connecting Montreal to Hull. This scenic route is a reflection of regional history as it ends near the heritage site of the canal on the Ottawa River. The main tourist attraction sites in the Lower Laurentians are heritage sites, in particular the Grenville Canal.

The village of Grenville is part of the Laurentides tourist region. Its main roads (e.g., route 148 and route 344) generate an influx of traffic, in particular many tourist attractions. This village is crossed by the Kingham River which flows into Grenville Bay. The McIntyre Bridge spans this river near its mouth.

History
After the construction of a merchandise warehouse in 1818, the first period of canalization of the Ottawa River dates from 1819 to 1830 under the direction of Captain Henry du Vernet of the Royal Staff Corps of Great Britain, with a hundred British soldiers. Hundreds of Irish immigrants united their working energies with those of French Canadians to dig the way for the canal. The Grenville Canal was operational in 1829. Finally, the network of canals on the Ottawa River was not fully completed until around 1843. In 1870, the upper portion of the canal was widened.

These initiatives to build military infrastructure are dependent on the military conflicts of 1812. This canal was part of the pipeline network, to supply Kingston and the Great Lakes in the event of a military conflict with neighbors south of the Canadian-American border. The purpose of these canals was to allow the transport of military troops and military equipment between the provinces of upper and lower Canada, thus avoiding the risk of being captured by the enemy on the St. Lawrence River. Of military design, the canals and locks of the Outaouais did not meet the demands of the growing commercial transport which was trying to establish itself on the Ottawa River. In the middle of the X19h century, commercial navigation took a big expansion on the St. Lawrence river; but struggled to relay to the upper Outaouais circuit.

Initially, six miles in length, the Grenville Canal was completed in 1833, with the three sections of canal: Grenville, Greece's point and Carillon. Partially flooded in 1962 by the rising water levels during the construction of the Carillon hydroelectric dam, only two thousand of the Grenville Canal remain visible and navigable; this non-submerged segment of the canal network is mainly in the Grenville territory.

From 1819, a regular barge service (Durham boat) was in use in the opposite direction of the river, between Hull and Grenville, under the aegis of Philémon Wright. However, the demand for transporting raw materials and goods was significantly higher than the capacity to transport. The ships were loaded with goods at the Grenville Quay in order to sail up the Outaouais, bound for the Rideau Canal in Ottawa or to the upper part of the Ottawa River.
 * Commercial shipping

The steam powered boats were put into service to ensure the superior link of the circuit, that is to say between Grenville and Hull: the ship "Union of Ottawa" and in 1828, the "Shannon", a powerful steamboat built in Hawkesbury, served this circuit. Even so, in the early part of the 19th century, commercial shipping on the Ottawa River had a rather modest record, with only two steamboats on the upper circuit.

The construction under the aegis of Hydro-Quebec of a hydroelectric dam (from 1959 to 1963) and of a modern lock at Carillon, irreparably modified this network of canals in the Ottawa River. Upon completion of this work, the water level rose over 62 feet at Carillon and 9 feet at Grenville. The portion of Greece's point of the canal was found submerged, as well as its hamlet. In addition, by gradually rising the water level, the rapids of the Long Sault were inundated, transforming them into a body of calm water.
 * Carillon dam

This military-type canal is recognized as a civil engineering work, emeritus for the 19th century. Nowadays, it is a distinctive historical draw and a municipal park to appreciate the great local history and nature.
