For the Employee
As an apprentice, you need to know as much about what you are getting into as your employer. The ITABC website has full information regarding the apprenticeship program, time lines, and what you are expected to know when you get your Red Seal.
Go to the ITABC website (https://www.itabc.ca/), click on Find My Trade and scroll to yours. Here you will find a Program Profile which will give you a start to finish road map of your chosen trade. The Program Outline is your Best Friend. Keep referring back to get the most up to date information.
Remember, it is up to you, as well as your employer to identify your weaknesses and improve on them!
