History

The federal district was created in 1976 from parts of Grenville–Carleton and Leeds ridings. It was initially defined as consisting of the County of Grenville and the County of Leeds, excluding the Town of Smiths Falls. Since 1987, it was re-defined as consisting of the United Counties of Leeds and Grenville, but this did not result in any boundary changes, as Smiths Falls is not part of the county. The 2003 redistribution defined the riding as also including the independent municipalities of Brockville, Gananoque and Prescott which are politically separate jurisdictions, but are geographically within the county, and therefore did not result in a boundary change either. With the 2012 electoral redistribution, this district lost a small portion of territory to Lanark—Frontenac—Kingston, following an annexation of a parcel of land by the Town Smiths Falls. In the process, the riding was renamed Leeds—Grenville—Thousand Islands and Rideau Lakes. At 49 characters, this is the longest riding name in Canada. Following the 2022 Canadian federal electoral redistribution, this riding will be renamed Leeds—Grenville—Thousand Islands—Rideau Lakes at the first election held after approximately April 2024.
