This is a shortened version of an invited talk at the XIII InternationalWorkshop "Lie Theory and its Applications in Physics", June 17-23, Varna,Bulgaria. A covariant canonical gauge theory of gravity free from torsion isstudied. Using a metric conjugate momentum and a connection conjugate momentum,which takes the form of the Riemann tensor, a gauge theory of gravity isformulated, with form-invariant Hamiltonian. By the metric conjugate momenta, acorrespondence between the Affine-Palatini formalism and the metric formalismis established. For, when the dynamical gravitational Hamiltonian$\tilde{H}_{Dyn}$ does not depend on the metric conjugate momenta, a metriccompatibility is obtained from the equation of motions, and the equations ofmotion correspond to the solution is the metric formalism.
