The following Canadian letters have a distinct property in common. Can you tell what it is?

From the above set, a further breakdown into two groups is possible. The first group contains the letters a, c, and g, while the second group contains the rest. The separating factor is related to the common property that all the letters share. Can you get that too?

I tried the same things as DJ. I have nothing useful to add, though I did notice that the letters a, c, g could stand for America, Canada, and Greenland...but I don't see how this would connect with the rest of it.
