SEP Float Plane hours recognised for CPL???

[187nj]

Hello all.

Apologies if I have posted this in the wrong forum but I couldn't find one dedicated to seaplanes.

My question is:

Can I do half of my hour building in a float plane, and those hours recognised by the good old CAA (realise it is FAA here in Canada) toward the issue of a JAA CPl? I have intentions to become a float pilot in Alaska after instructing (land) here in the UK.

Also:

What are the minimum requirements to be a float pilot under the FAA?

Thanks.
