In practice, I don't believe any U.S. states attempt to regulate the mere linguistic usage of the word "engineer", the way that Canada does. Pretty much anyone can call themselves an engineer, or have the word "engineer" in their job title. What's regulated is that there are certain situations, mainly in civil engineering, in which a required document can only be signed off on by someone with a state engineering license.
