First off when you put in your component transfer the army puts you where they need you. So not only might you not get 3RCR but 1 or 2 RCR, you could potentially be sent out west to the Patricia's.
As for Pay, the pay guide can be found here
http://army.ca/forums/threads/13044.0.html. What IPC level you will get when you join the Reg Force will depend on your total amount of Class A, B, C days.
As for financial benefits, besides free healthcare, fitness facilities, pension. There a a number of "fringe" type benefits that you can use.
-Great financial planning and investment for an extremely low rates through SISIP(not to mention cheap(er) insurance.
-The ability to buy high priced items from the canex retail store on a "no interest plan".
-Another Canex thing is the ability to get Auto insurance or house insurance though The Personal. Although I really don't know how good it is.
-Usually you'll get the opportunity to buy lower priced tickets to to sports, or other attractions in your area.
That just a few, I'm sure the collective membership will fill in a few more.
