Yes, you can transfer any existing TFSA, RRSP or RRIF funds into this plan.
A transfer of your TFSA or RRSP from another financial institution does not affect your TFSA or RRSP contribution limit.
After you’ve completed your transfer-in, make sure to reduce your “Other savings” amount in your account so that your retirement plan reflects this new information.
