initiated by premier Mike Harris under his Common Sense Revolution platform in 1995, numerous highways deemed to no longer be of significance to the provincial network were decommissioned and responsibility for the routes transferred to a lower level of government, a process referred to as downloading. Due to its proximity to Highway16, which was in the process of being upgraded to Highway 416, the entirety of Highway31 was downloaded in 1997 and 1998. On April1, 1997, of the route, from Regional Road8 (Mitch Owens Road) to the Ottawa city limits south of Regional Road32 (Hunt Club Road), was transferred to the Regional Municipality of Ottawa–Carleton. On January1, 1998, the remainder of the route was downloaded, including to Ottawa–Carleton and to the United Counties of Stormont, Dundas and Glengarry.
