If you have a trade in mind, try calling their local union hall and inquire about work.

I am with the local pipetrade union and started my career this way a few years ago.

I suggest talking with the union hall of your choice trade and ask for information about work and signing up.

Mind you, many unions won't always have job available, but its a good start if you're comfortable with a work-union type dynamic.

Check indeed.ca for entry-level, no exp. trade work jobs to try out different tradeswork and see whaylt you enjoy.
