You can still open your non RRSP+ account over the phone. You must contact Saving Services to have an agent accompany you through the process.
You can meet with the local representative (LR) in your workplace, who'll help you fill out the required appendix and, as the case may be, other documents.
You can also submit a request to transfer your RRSP+ savings to a non-RRSP+ account directly in your online account.
