To me, a skeg drops down out of the stern and is adjustable to help with weathercocking. A rudder pivots at the stern on cables connected to foot pegs and assists in steering. To me what the OP is talking about is a fin - like on a paddle board. If it helps go for it.
Not aware of any canoes with skegs, but there are well-known open-water canoes with rudders - like the Kuger Sea Wind (maybe others) and the Mad River Monarch. Looks like SouthernKevlar has/had a Monarch - he could probably weigh in.
