Hi Ken...

Okanagan (hope that is how it is spelt) Helicopters had a hangar/offices and maintenance at Kingcity on the west side of the runway and Kingair Maintenance I think it was called was on the east side of the runway which paralleled HYW 400.
The "Toronto Flying Club" which moved from the Toronto Island Airport, now called Toronto City Center Airport I think and I knew it as "King George V Airport" moved to Kingcity on the West side of the runway. That flying club has long gone now to as far as I know.
When they built Canada Wonderland we lost both Kingcity and Maple Airports to the political idiots. We also lost a home which sat on the Maple Airport, was our 400 Flying Club clubhouse as well as the best designed house in Upper Canada way back when.

All in the name of "amusement" and "political progress".

Going back to your "Seabee", good aircraft in the air and on the water. It had a throw over yoke much like the DHC-2 "Beavers" and a twin engine Seabee was also manufactured. Never flew the twin but saw them many times.
I would think a good Seabee today would be a fine catch and bring a good Canadian Dollar on the market.
Again thanks for those wonderful shots, if you find anymore float planes or seaplanes hope you post them. ;)
Cheers...Happy Landings...Doug
