No Salary Stubs- Paid Perdiem, how to ensure the T4 has correct income

[acevee]

Hi All,

I am applying in CEC category, I am paid Salary = Canada Perdiem+ Car Hire allowance+Indian Salary

As a result the salary given in the Canada employment letter is much higher than that in my last year T4

How to ensure :
1. T4 has correct salary deduction.
2. What to provide as proof if Salary stubs are not avaible.
