O'sullivan Lake Water Aerodrome

Administrative closure. The aerodrome was not closed due to an accident or physical change. Instead, it was de-listed from official publications. This is common for small, privately operated sites where the operator (likely a local lodge) chooses not to maintain the official registration with Transport Canada. Floatplanes can still legally operate on the lake without the official designation, making the registration an unnecessary administrative burden for the operator.

The physical site is the location of the active O'Sullivan Lake Outfitters lodge. While the official 'CA-0607' aerodrome is no longer registered, the lake itself remains actively used by floatplanes. The lodge continues to advertise and facilitate fly-in packages for its guests. The lake now functions as an unregistered, private landing area, where pilots land at their own discretion, typically with prior permission from the lodge.

The aerodrome's sole purpose was to support fly-in tourism for the remote O'sullivan Lake area in Northern Ontario. It was directly associated with a local fishing and hunting lodge, O'Sullivan Lake Outfitters. Operations consisted of charter and private floatplanes (e.g., De Havilland Beavers, Cessna 185s/206s on floats) transporting guests, staff, and supplies to the lodge. Its significance was purely local, providing a critical transportation link for the outfitter's business.

There are no known plans or prospects to officially reopen or re-register the water aerodrome. Since the lake is fully functional and serves its intended purpose without the official designation, there is little to no incentive for the private operator to undergo the administrative process and potential costs associated with re-registering the site with Canadian aviation authorities.
