Abstract
In this paper we discuss the problem of covariance of one-loop diagrams in a canonical formulation of Yang-Mills theory. We show that one-loop diagrams to all orders can be made covariant provided they satisfy certain Ward identities. Verification of these Ward identities to second order in the coupling constant shows that one must introduce renormalization counterterms into the theory.
