Grenville (French pronunciation: [ɡʁɛnvil]) is a borough of the municipality of Grenville-sur-la-Rouge in Quebec, Canada,[1][2] located on the left bank of the Ottawa River.
The village municipality that shares the name "Grenville" remained independent; it borders on Grenville-sur-la-Rouge but is not part of it.
The name "Grenville" comes from William Wyndham Grenville, a British statesman who served briefly as British prime minister (1806–1807).
While Canada was still under British rule, a canal was built by the military to bypass a series of rapids in the Ottawa River.
The canal and the settlement that arose in the region were named in Lord Grenville's honour.
