The short answer is no – there is no technical mechanism to transfer TFSAs into RRSPs (or vice versa).
That said, you can sell what is in your TFSAs (say sell $1000 worth of investments) and contribute this to your RRSPs, but for the most part, this won’t make a lot of sense. Overall, you are better off either contributing to your RRSPs directly by some other means (RRSP top-up loans) or saving that contribution room and using it next year.
