I’ve no knowledge of US or Canadian education structure and design employment, but I am a believer that most creative degrees are a bit of a means to an end, in that I mean they generally serve to develop a good portfolio, rather than give you a certificate employers require to see.
There is of course some “hard” knowledge, manufacturing data, the importance of ergonomics and how to apply them etc etc.
For someone with no formal training, the work you’ve shown is of a decent standard. Might it be worth contacting some local design firms (I’ve just googled and found two), and asking about work experience (I believe you call this “interning” 
), mentoring, general advice, a junior position…?
