I would stay in the Lower Mainland and contact Fort Langley Air. Dave Hamel is a great guy and I have never met a finer instructor. He has been teaching float flying for something like 30 or 40 years. The flying is very scenic too cutting up the Harrison River from the Fraser low level and working on Harrison Lake...
I learnt more about flying from my 7 hours with Dave than I did from any other instructor I have had...
The plane is a C-180 and flys well. I heard that they may also have a Super Cub now too...
