Change in trades suggestions

Currently a concrete line pump operator in the Okanagan.

$31/hr guaranteed 30 hours a week minimum.

Job is hard on the body looking for a change in trades. However I'm not 18 living at home. I have a mortgage and a wife.

I'm curious in starting a trade apprenticeship but I'm worried they might start me off at like 18 to 20 bucks an hour.

Interested in hvac electrical or plumbing.
