LIRA (Locked-In Retirement Account): This plan falls under provincial jurisdiction. If your former employer was governed by the law of the province you worked in instead of federal law for pension plans, then you would have the option to put your retirement pension plan value in a LIRA upon leaving your employer.
LRSP (Locked-In Retirement Savings Plan): Same as a LIRA but for employer whose pension plan was under federal law.
RLSP (Registered Locked-In Savings Plan): This plan is under Federal jurisdiction and is used to transfer a one-time 50% unlocking from a LRSP account.
LIF (Life Income Fund): Can be federal or provincial but this plan exist since that most other types of plan have a rule where the funds must be transferred into a LIF before you turn a certain age (normally 71) at which point you are legally obligated to take out a minimum amount every year.
Registered Retirement Income Fund (RRIF): Similar to a LIF but for regular RRSP. Meaning the funds in your RRSP must be transferred to a RRIF before the end of the year that your turn 71.
Prescribed Retirement Income Fund (PRIF): Only available for LIRAs that were under Manitoba or Sakatchewan rules. Similar to a LIF but with the major distinction that there is no cap on the amount of funds you can take out of them. You can therefore withdraw all of the funds in the same year if you wish to do so.
Locked-in Retirement Income Fund (LRIF): Same as a LIF but exclusive to the province of Newfoundland & Labrador.
Registered Pension Plan (RPP): This is a pension plan while it is still with your employer. Once you leave the employer the RPP can remain with them until you are allowed to start receiving a retirement benefit or it can be converted to a LIRA or LRSP depending on whether your employer's is governed by provincial or federal law.
