There's no doubt that gas-powered appliances play an extremely important role in our lives. They're used for cooking meals, safely storing food, heating buildings, and many other purposes in residential, commercial, and industrial settings.

However, they must be properly installed and maintained by trained professionals to function effectively and safely.

Installing and servicing these types of appliances is the job of the gas technician. It's a challenging and rewarding occupation that can also pave the way for plumbing, HVAC, and appliance technician work.

If you're interested in pursuing a gas tech career in Ontario, your specific duties, salary, and job opportunities are highly dependent on the level of licensing you achieve.

Considering heading back to school to train for a career in the construction trades?

You’re probably looking at which trades are most in demand so you can be sure your educational investment will pay off with a steady, well-paid job.

You’re also probably looking to build a diverse set of skills, so you’ll be eligible for several different kinds of employment after graduation (keeping your options open).

One of the smartest ways to fulfill the above criteria is to select a “combined” pre-apprenticeship training program. You’ll learn skills from two different trades that are often paired together on the job. This means double the technical knowledge and double the job opportunities.
