Query: Canonical charges and asymptotic symmetry algebra of conformal gravity   We study canonical conformal gravity in four dimensions and construct the
gauge generators and the associated charges. Using slightly generalized
boundary conditions compared to those in \cite{Grumiller:2013mxa} we find that
the charges associated with space-time diffeomorphisms are finite and conserved
in time. They are also shown to agree with the Noether charges found in
\cite{Grumiller:2013mxa}. However, there exists no charge associated with Weyl
transformations. Consequently the asymptotic symmetry algebra is isomorphic to
the Lie algebra of the boundary condition preserving diffeomorphisms. For
illustrative purposes we apply the results to the Mannheim--Kazanas--Riegert
solution of conformal gravity.
