Note the word 'engineer' is limited in use to those who have an engineering license to practice engineering. In Ontario, see here:

If a person uses the title “professional engineer”, or “engineer”, or any other occupational title that might lead to the belief that the person is qualified to practice professional engineering, or uses a seal that leads to the belief that the person is an engineer, PEO will prosecute the matter through provincial court. Fines for people found guilty can range from $10,000 for a first offence, to $50,000 for repeat offences.
So use caution in identifying individuals as 'engineers' when they are not authorized to be identified as such.
