Mr. Mke - You may not take a gun into a hospital with or without a CPL open carry or otherwise.
I am not a lawyer...
You may want to reread the laws again: Open Carry in a hospital is quite legal if you have a valid CPL. Same with schools, bars, entertainment facilities, etc. Please read the laws before posting incorrect information. Especially for your first post.
Here is the law:
750.234d Possession of firearm on certain premises prohibited; applicability; violation as misdemeanor; penalty.
Sec. 234d.

(c) A court.
(d) A theatre.
(e) A sports arena.
(f) A day care center.
(g) A hospital.
(h) An establishment licensed under the Michigan liquor control act, Act No. 8 of the Public Acts of the Extra Session of 1933, being sections 436.1 to 436.58 of the Michigan Compiled Laws.
(2) This section does not apply to any of the following:(a) A person who owns, or is employed by or contracted by, an entity described in subsection (1) if the possession of that firearm is to provide security services for that entity.
(b) A peace officer.
(c) A person licensed by this state or another state to carry a concealed weapon.(d) A person who possesses a firearm on the premises of an entity described in subsection (1) if that possession is with the permission of the owner or an agent of the owner of that entity.
