Caledonia/Grand River Seaplane Base

The closure was due to the cessation of private operations, not a specific incident, accident, or military conversion. As a privately registered facility, its existence depended on the owner maintaining the registration with Transport Canada. The closure likely occurred because the owner sold the associated property, no longer operated a seaplane, or chose not to continue with the registration process due to cost, liability, or lack of use.

The site is no longer a registered aerodrome. The geographic coordinates point to a section of the Grand River in Caledonia, Ontario, adjacent to residential homes on the north bank and public parkland (Kinsmen Park) on the south bank. The river in this area is now used for general public and private recreation, including fishing, kayaking, and motorized boating. Any specific infrastructure that may have supported the seaplane base has been removed or repurposed for private, non-aviation use.

The Caledonia/Grand River Seaplane Base was a small, private-use water aerodrome. Its significance was entirely local, providing a registered and legally recognized landing and takeoff area on the Grand River for a private owner and other permitted pilots. It handled light general aviation floatplanes, such as Cessna, Piper, or de Havilland aircraft modified for water landings. It was never a commercial airport, had no scheduled passenger service, and did not have extensive infrastructure; the 'base' likely consisted of a designated water lane on the river and an associated private dock or ramp on an adjacent property for mooring and access.

There are no known plans or public prospects for reopening the Caledonia/Grand River Seaplane Base. Re-establishing a registered aerodrome would require a new proponent to complete the complex and lengthy registration process with Transport Canada, including community consultations. Given the increased residential density along the river and potential community concerns regarding noise and safety, a reopening is considered highly unlikely.
