In the framework of canonical quantization we discuss the construction of physical quantities in gauge theories. It is shown that to treat the problem consistently one needs first to specify the A0 - timelike component of vector potential. There are just the certain restrictions on A0 functions that may give rise to the vacuum degeneracy in the theories with non-trivial minimum of the scalar potential. However, this degeneracy has nothing to do with the vector boson mass generation and, besides, never reveals itself in the perturbation theory. In non-Abelian theories the boundary conditions on A0 are to be carefully taken into account when the realization of global charges algebra on physical states is studied.
