Abstract
The general uncertainty principle applied to gravity can be implemented as a set of modified Poisson brackets in the canonical formalism. As such, the theory is not canonical and the resulting equations of motion do not lead to a covariant metric. We construct a Hamiltonian that when applying the usual canonical formalism gives a closed algebra and equations of motion that result in the original metric obtained by using distorted Poisson brackets. The resulting theory is thus rendered canonical and covariant. We then covariantly couple scalar matter and dust to the modified gravity to allow the study of dynamics.
