If you are in an open Canadian type canoe I think bicycling gloves will
be fine.
If you are in a kayak (2 blade paddle) pogies are better for the cold.
If you have blister problems and this is the sole rason for gloves you
might try Mole Skin or a pre-emptive band aid. It won't be long before
you don't need any protection the your hands will toughen up.

Cycling gloves may be the real deal for right now though.
Good luck
