You can transfer up to $10,000 per calendar year into your SPP account from existing RRSPs, RRIFs and unlocked RPPs. Transfers must be done in cash, vs. in kind, and the deadline for receiving the funds at SPP each year is December 31.
Funds transferred to SPP are subject to all SPP rules including the lock-in provision. This means your transferred funds become part of your SPP account and can only be accessed when you choose a retirement option. Since these are direct transfers between plans, there are no tax implications.
As part of the transfer process, you will be asked for investment instructions directing funds to the balanced fund and/or the short-term fund. Your financial institution may charge a fee for transferring these funds to SPP; SPP does not charge you a fee to transfer money.
