Yes. You'll see the list there, and I think, to Mr. Ruff's question, paragraph 117.07(2)(g) includes a member of “the government of a province or municipality who is prescribed to be a public officer”. I think the missing piece will be whether the people he's concerned about are so prescribed.
The larger point is that nothing in G-22 changes the list of public officers who enjoy these immunities. All this does is give them immunity for certain activities with respect to firearm parts.
