If you want the rating combine it with a holiday in British Columbia Canada, I did mine with Cooper Air in Victoria on a C185
I also did a few hours in a freinds Beaver which really is the Daddy of all bush planes
It was fantastic! go in the summer the scenery is stunning and a floatplane is the only sensible vehicle for seeing it from check out their site at.

you get a temporary Canadian License issued from transport Canada first do the Canadian rating then come back to UK and sit a "seamanship" exam with the CAA pass that and you get the SEP (SEA) added to your license.
saving my pennies for a return trip this summer!
