The money that they take out of their RRSP will be taxed as regular income  at higher rate than what they currently are getting taxed at with their dividend  setup.

what would be the reason  to max out your TFSA before RRSP?.  What would be the reason to be putting money into a RRSP at all?   Save a bit of tax now to pay at a higher tax rate later?

Is  their investment advice  getting them better returns....  by 2.4% than a basket of ETFs?
