Arrears are retroactive permanent disability benefits, paid as a lump sum, dating from the onset of permanent disability.
PurposeThe purpose of this policy is to provide guidelines respecting arrears payments for permanent disability benefits.
Initial pension assessment
Arrears are calculated for all periods where temporary benefits were not paid or were less than the monthly permanent disability benefit. The arrears amount is the difference between the permanent disability benefit and temporary benefits already paid for that period. Information about the calculation of permanent disability benefits can be found in 18-07-04, Calculating Permanent Disability Benefits.
The WSIB usually determines the dating of arrears at the time of the permanent disability assessment.
Permanent disability reassessment
If a permanent disability benefit is increased after reassessment, the increase dates from
- three months prior to the date of the request, or
- an earlier date if supported by clinical evidence.
If a permanent disability benefit is increased as a result of an objection, the increase dates from the same arrears date as the previous permanent disability benefit.
This policy applies to all decisions made for entitlement periods on or after January 1, 2018, for accidents prior to January 2, 1990.
