That part you cited in wikipedia has no citations and may not be legally correct. This is something that is codified in Ontario law [1] (not sure about other provinces, but I believe it is harmonized federally -- in Quebec the title ingenieur/engineer is protected.). This law has been tested several times (example in [2]). More info here [3]. Even Microsoft had to give up the use of the term "engineer" in Canada after being hit with lawsuits [4].

also 4 is directly relating to training certs for a "systems engineer" not job titles which does make some sense, microsoft still seems to use the title "software engineer" in canada for jobs
(1-3 are not what i would consider unbiased sources)
Edit: According to wikipedia, there are plenty of titles in Canada like locomotive engineer used by a train operator even though the position is unrelated to the Professional Engineer license [1].
