So if a player is 1400 in Canada it's like 1200 in the U.S.?
How do Canadian ratings compare with USCF ratings. Are they comparable?

No, IF the 200 point inflation is true, then over a large number of players it will be true for the average.
There will be large individual variations, though, some players will have a higher US rating, some will have a higher Canadian rating, and some will be the same. You cant make a prediction for an individual.
Are they closer to fide or uscf ratings?
