The GFCI requirements might actually make Canada break with it's love of the split receptacle. I suppose the best solution would be GFCI breakers and separate circuits to the box. In the US we can get NM with 4 wires, 2 neutrals but it is not that common. I liked the concept at my house but I went with a 4" box and 2 receptacles in each counter top location, one duples on each circuit, then a regular GFCI receptacle works. (use a deep box)
