Hi Bob...

Balloons have Registered Numbers or Letters just like Aircraft, they have a Licenced Pilot aboard and must comply to all Transport Canada Air Navigation and Air Regulation Rules.
Therefore they are considered Aircraft just like a Helicopter would be considered an Aircraft.
Just a bit of information, a Float Aircraft, Seaplane or Amphibian being an Aeroplane or Helicopter should also carry besides the radio for use by Aircraft, a Marine Radio. Those who land on water must comply with Marine Navigation and Regulation Rules set out by Transport Canada.
Years ago we never carried a Marine Radio when flying in and out of the bush off floats, or landing the PBYs/Canso on water or the DC3s on ice with wheel/skis.
Most float aircraft like the Cessna 180/185, Pipers etc. were lucky to even have a radio when flying off floats in the bush until Transport Canada started to regulate everyone.
Today most commercial companies that fly into and out of busy harbours would have both radios on board.
Float and Seaplane flying is on a comeback now, there was a large decline during the 80s and 90s but most new marinas being built now are making facilities for docking the water aircraft and offering fuel/oil.
Although off topic, General Aviation is also on the upswing here...

Thanks Bob for your information on the setting, will give it a try later...
