Hey there Pixel,
As far as standardized curriculum, there isn’t a whole lot set up currently, but there are more programs getting started. I apologize, but I am pretty unfamiliar with Canadian options for technical art training, so I’ll speak to the American options that I know of.
I teach in a masters level program out of the University of Central Florida, called the Florida Interactive Entertainment Academy (FIEA). Technical Art is kind of set up like a sub track/specialization option for the Art program there. It is three semesters + a semester long internship of production environment education.
I think SoCal also has some tech art instruction set up, and I believe that something is in the works down in Texas, but I am a bit fuzzy on that. Anyone who knows any other programs that are up and running, let me know, I’d love to hear about them. Most people I have spoken with never got formal instruction in school, and had to pick it up as they went.
If you really want to go back to school, then I would recommend any school that has a solid tech art program/track set up in a production environment (this, to me, is a key part of getting any practical experience as a TA while in an educational environment). If you are just looking to build skills, this forum is filled of many awesome people’s opinions on what makes a solid TA. Find an area that interests you and research/mad science the hell out of it.
Hope this is helpful,
Mary
