Computer techs are very underpaid in Canada. One place I got paid around $30/week.... that was in the 1990s though. (the coworkers were awesome but the employer was abusive as all anything)
I've worked at a few places since though and wouldn't recommend that work to my worst enemy. Better pay and hours in fast food, and less customer abuse typically.
One of the things rarely mentioned is that there's two people who get blamed when tech fails - the user themselves, and the tech who comes in to fix it. Not a great recipe for happy encounters or healthy cultures.
