Why don';t you do this...
Apply for online courses at ilc.org
get your grade 11 uni phys or grade 12 uni/college physics.
Go get your eng and math while you're at it. They also offer inclass day time quad type semesters (running every 2 months/sem sept-june)
Once you get this done and hopefully before JAC,
http://electricalapprenticeship.ca/apply/construction.html , posts their annual intake.
Annual intake is FREE and all it takes is for you to have your credentials.
Once you've done the application and aptitude test, approx 3-4months before you hear back from them, they'll tell you to come back for an interview. If you're in, they'll put you in a 2 week class to get your cards (cpr and first aid, pre-app, fall protection, whmis cards). After the 2 week period is done, you're off to work as a pre-apprentice. 1800 hours before you move onto a first year apprentice. You start getting paid the second you start working as a pre-app). It's relatively easy and i've told my friends to do it too. You'll meet a lot of guys in your class. I had some chefs, IT, sushi owner, television broadcast crew, people with dead end jobs, labourers etc etc.
I'd say if you really care about yourself, you'd push for the best. These things usually require small sacrifices. Myself for example, I was getting paid about $25/hr as a lineman w/ good benefits and the max income was about low $30s from what i heard from the old timers. I had a conversation with 309A electrician. He told me to apply and take the risk. So i did. Got paid $13/hr as a pre-ap. now my wage is higher than my previous job and it doesn't stop there. The benefits is also ridiculously good.
People always say to get your eng, math and sciences as this will open up windows for you. It's true man. Get those courses done!
