I believe that in Canada, and certainly in Alberta, the titles are very much controlled. The regulatory group APEGA has a Professional Engineer designation for software engineers as well
Another example: the University of Alberta has a software engineering program.

Search on Canadian job sites and you will find hundreds of software engineering jobs across Canada (including Alberta).
Other examples of non-PE engineers include stationary engineer (people who operate boilers) and locomotive engineer (people who operate trains). They may have their own regulations, but it is entirely distinct from Professional Engineers.
