Vancouver - Truck Test Advice Info, Visa and Job Information

Can anyone point me in the right direction of how I would go about taking the test to drive trucks out of Vancouver.

I currently hold a UK Class One and understand I need an A+Z licence over there, are there particular companies who train you up, and if so can you provide website or contact details.

Also, it is very difficult finding out about the nature of jobs and companies over there, and I would appreciate any information on good companies over there.

Finally, I am not expecting a bed of roses over there and understand there is a downside to all things in life so please dont let this post go the route of other posts!

I have a good friend over there who can help me out with accomodation etc, but I just need the initial info to start the ball rolling.

Thank you for all your help.
