What is the Precise Meaning of "Canonical" in Quantum Gravity Context
I keep seeing "canonical" in the context of the expression "canonical quantum gravity" and it is clear the meaning has a precise defintion. But I haven't seen it articulated anywhere and a search doesn't bring up anything useful, although it does bring up a surprising number of old PH threads. I know what the word means, in general, but nowhere do I see it described specifically in the context as used in the term "canonical quantum gravity."
What precisely does "canonical" mean as a descriptor for quantum gravity?
From context it seems to mean something like: "using a straightforward/naive/uncomplicated/standard quantization strategy," but clearly that's not the precise definition. If possible, I'd like a two types of answers. First, in laymen's terms and second in more precise mathematical/physics language.
Or is it as simple as a gravity theory that uses "canonical quantization?" It seems to be something more specific than that. But if this is all it means, then what precisely does "canonical quantization" mean in the context of the history of LQG development?
As always, any pointers to good papers or references are appreciated.
