No RRSP income isn’t deducted (I guess the policy could specifically say they will, ask the insurance company).
Besides, your just moving it between tax sheltered investments, it is not really income.
Do a forum search for ‘RRSP’.
They don’t have access to our income taxes but you don’t want to hide things from them.
Investment income is ok too but I’d get the insurance company’s opinion.
Do you have your benefit booklet?
If not, get it from your employer.
It should say what they can deduct.
