In Canada, "Engineer" is a protected term...you legally can't use it unless you are a p.Eng. The idea is that Engineers are bound by a series of standards and assume responsibility of their efforts...especially around designs where human health/safety are concerned. And I get that. But, to say that engineering, as a rigorous discipline can only be practiced by engineers, seems wrong to me. Good practices are (or should be) universal and executable by anyone, and not the blessed few.
