Lac Gagnon Seaplane Base

While no official reason is cited, the closure is almost certainly due to private de-registration. Small water aerodromes like this are typically registered by a private owner for personal use or a small commercial operation (e.g., a lodge). The closure would have occurred because the owner ceased operating aircraft, sold the associated property, or simply no longer wished to maintain the official registration with Transport Canada. There is no evidence of closure due to a major accident, military conversion, or significant economic failure of a large commercial entity.

The physical site of the former seaplane base is the water of Lac Gagnon and the adjacent shoreline. Satellite imagery of the coordinates shows a residential and recreational shoreline with private homes, cottages, and docks. There is no remaining visible, dedicated infrastructure such as a commercial ramp, fuel depot, or public terminal that would identify it as an active seaplane base. The area is now used for general recreational activities like boating and cottaging. While private seaplanes may still land on the lake, they would do so as a visitor to a private dock, not as a user of a registered aerodrome.

Lac Gagnon Seaplane Base was a registered water aerodrome that served the recreational and remote access needs of the Lac Gagnon area in Quebec's Outaouais region. Its primary operations would have included:
- **Private Aviation:** Providing access for floatplane owners to their private cottages and properties on the lake.
- **Light Commercial/Charter:** Potentially serving as a drop-off and pick-up point for small air charter or 'bush pilot' operations, flying tourists, hunters, and fishermen to and from the area.
Its significance was purely local, representing a typical Canadian water aerodrome that facilitates access to areas with limited road infrastructure. It was not a major transport hub.

There are no known plans or prospects for reopening the Lac Gagnon Seaplane Base under its former designation. Re-establishing a registered water aerodrome would require an initiative from a property owner or business, who would need to complete the full registration process with Transport Canada. Given its history as a small, private-use base, any future registered operations on the lake would likely be an entirely new registration rather than a 'reopening' of CA-1127.
