Despite this topic being a good 10 days, I thought I'd clarify something. To get 'sweet pay', you don't have to be in the 'Mo for 3 years and three full class B summers. I was in for just under a year with no class B time and I'm getting more then double what a 'normal' OCdt would make (I clear about $2800 a month after taxes).
If anyone is interested I can find the CBI I used to justify (and eventually receive) getting the proper pay.
EDIT: The CBI ref I used was 204.211(10)(b) found at http://www.forces.gc.ca/dgcb/cbi/pdf/CBI_204_Sec_2.pdf
That was the ref used to justify me getting the amount I get now. Multiple ROTP types who joined from the 'Mo with less then a year in got vastly better pay, so don't just let it slide, you probably are entitled to it if you have at least finished BMQ.
