Lac Pontbriand Water Aerodrome

The closure was administrative in nature. As a private-use water aerodrome (indicated by the 'CA-' prefix in its identifier), its registration with Transport Canada was likely allowed to lapse by the owner or operator. This can happen if the owner ceases flying, sells the associated property, or chooses not to maintain the official status. There is no evidence to suggest the closure was due to a specific accident, economic failure of a commercial business, or military conversion.

The site is Lac Pontbriand, a developed residential and recreational lake within the municipality of Rawdon, Quebec. The lake and its shoreline are heavily used for non-aviation purposes, including boating, swimming, fishing, and cottaging. There is no remaining aviation-specific infrastructure visible. While it is physically possible for a floatplane to land on the water, it is no longer an officially registered or recognized aerodrome. Any such landing would be considered an off-aerodrome operation, subject to Canadian Aviation Regulations regarding safety and local bylaws.

Lac Pontbriand Water Aerodrome was a registered private-use seaplane base. Its significance was purely local, serving the needs of private floatplane owners for recreational aviation. Operations would have been seasonal (summer months) and consisted of light, single-engine floatplanes like a Cessna 185, Piper Super Cub, or de Havilland Canada DHC-2 Beaver. It was not a commercial airport and had no scheduled services, FBOs (Fixed-Base Operators), or significant infrastructure beyond potentially a private dock or ramp. It represented one of thousands of small, private landing sites that form the backbone of general aviation in Canada's lake-rich regions.

There are no known plans or public prospects for reopening Lac Pontbriand as a registered water aerodrome. Re-establishing an official aerodrome status would require a proponent to undertake a formal registration process with Transport Canada. This process would likely involve consultations with the local municipality of Rawdon and residents around the lake, who might raise concerns about noise and safety. Given the established residential and recreational use of the lake, the prospects for reopening are considered extremely low to non-existent.
