Just to clarify, there's no issue in Canada with "software engineer" specifically. "Engineer" is the protected term, and you have to be licensed to use it. So the issue applies to calling yourself any kind of engineer without being licensed.
If you are a licensed professional engineer in the software field, you can refer to yourself as a software engineer. This is just uncommon because there are not a lot of programs that grant BEng in software, the licensing is rarely relevant, and most people take CS anyway.
