It comes down to the difference between the US electrical code and the Canadian electrical code.
The NEC has allowed a 20 amp circuit-breaker to be connected to 12 gauge wire and then to 15 amp outlets. (some local codes do not allow this, but the NEC does).
The NEC does NOT allow a 20 amp CB connected to 14 gauge wire and then to a 15 amp outlet.
Some electricians believe this "mix" of 15amp/20amp is not safe and use 15 amp breakers, 14 gauge wire and 15 amp outlets, and this is allowed under NEC.
Generally kitchen circuits have required 2 each, 20 amp circuits, for years these outlets were 15 amp outlets though. In recent years there has been a push to require all kitchen outlets to be 15/20 amp outlets.
One last point, while we talk about the NEC, it is NOT the "national" code. Electrical code is a state function, while most state/local districts use the NEC, not all do.
