Salary for British Columbians

Hi,
I'm just wondering what the starting salary is like for a BScN / RN in BC.
My aunt is a RN and she told me that nurses work 48 hours a week 4 shifts a week and 12 hours a shift.

1) So.. how does this work with the over time..?
8 hours a shift is regular 26.~$/hr pay? and the rest of the remaining 4
hours are ~40$/hr?

Or.. do they get paid weekly .. so 40 hours is 26.~$/hr and the
remaining 8 is ~40$/hr?

Or.. is there no over time pay at all until after 48 hours?

2) Also.. I'd like to know how nurses are paid during the night and the
day.. how much more would a nurse make at night?

3) Is it possible for a nurse to "hog" all the hours? Since there is some kind
of shortage arising.. is it possible for nurses to take on as many hours as they can physically handle in a week?

4) How long does it usually take to move up the payscale? Would it be
dependant on the hours worked, the years worked, or.. just based on
performance?

5) This question is kind of off compared to the other ones.. but how much
would a clinical nurse instructor be making? for.. LPN's or student BSN's?

All information is greatly appreciated, thanks!

Thanks for the quick reply fergus,

I've actually got another question for you..
I really want to be an ER nurse because I hear its very exciting and fast paced.. I know that if I want to be an ER nurse in Vancouver, I'll need to go through BCIT's post-RN program to be eligible.. is it the same in the states? or would I just need to go through some sort of orientation in the states to become a ER nurse?

Most places in the US have their own orientation, so you don't need a particular course to apply. Hospitals in Vancouver would take you without the BCIT courses if you have experience in the specialty area already. I got hired as an L&D nurse before doing the courses because I had experience as an L&D nurse in the US before living there.
