Found another code CEC 26-712(d) where it refers to kithen receptacles it states either "15amp SPLIT or 20amp T-slot" receptacles.
So until they make a 15amp GFI that you can split - in Canada - I say no!
The new T-Slot GFCI Receptacles are rated for 15amp and 20amp.
My understanding is that although the 15amp GFCI is Rated for 20amp, the configuration is meant for 15amp only. However, the T-Slot is rated and will take a 15 or 20 amp cord.
