Yes, floatplanes are more expensive, but still cheaper than in the UK. I used to rent a Super Cub on floats for C$100 (about £50) an hour wet (in both senses of the word).
Admittedly this was a few years ago, but the owner told me he was charging double his normal rate for a wheeled Super Cub, because of the insurance premiums.

I wouldn't like you to think I'm made of money! I had one trip in the Bulldog just to see how it compared with the Chipmunk. I'm an old time UAS pilot (pre-BEagle, which really dates me!). The Bulldog was nice, but the Chipmunk is still my all time favourite
