Lac Mandeville Water Aerodrome

The closure was for economic and operational reasons. The aerodrome, which operated under the official Transport Canada Location Identifier CTM2, was a satellite base for the company 'Hydravion Aventure'. The company likely closed this location to consolidate its operations at its larger, primary bases, such as the one at Lac-à-la-Tortue (CSU3). There is no evidence to suggest the closure was due to a specific accident, military conversion, or regulatory enforcement action.

The site is permanently closed to all aviation traffic. The designated water landing area on Lac Mandeville is no longer a registered aerodrome and has reverted to general public use for recreational activities such as boating, fishing, and swimming. Any shore-based infrastructure that supported the aerodrome, such as docks or offices, has likely been removed or repurposed for private residential or non-aviation commercial use. The ICAO-style identifier CA-0572 is a non-official code used by some third-party databases to catalogue the closed aerodrome; its official identifier when operational was CTM2.

When active, Lac Mandeville Water Aerodrome (CTM2) served as a seasonal seaplane base in the popular Lanaudière tourist region of Quebec. It was operated by Hydravion Aventure, one of Quebec's most prominent floatplane operators. The aerodrome handled general aviation floatplanes, such as Cessna 172s, 180s, and possibly De Havilland DHC-2 Beavers. Its primary operations included:
- Sightseeing flights over Lac Mandeville and the surrounding scenic area.
- Introductory flights and seaplane rating flight training.
- Charter services for access to remote cottages and lodges.
It played a role in the local tourism economy, providing a unique attraction and transportation option for visitors and residents.

There are no known plans or public proposals to reopen the Lac Mandeville Water Aerodrome. Re-establishing a certified water aerodrome would require a new operator to make a significant investment, navigate the complex Transport Canada certification process, and likely engage in consultations with local residents and environmental authorities. Given that the former operator has consolidated its business elsewhere, the prospects for reopening are considered extremely low to non-existent.
