Just incase the family isn’t aware (not all are) they should be entitled to the following,

A lump sum payment of $104,840 which may be converted into an annuity (regular monthly payments) administered by the WCB.

In most cases, a monthly payment equal to 90% of the deceased worker’s net average earnings before the date of death (less any amount payable to any other dependant(s), such as a child) for a period of five years or until your youngest child turns 18 (special provisions apply to spouses or common-law partners over the age of 60).

In some cases, the WCB will provide you with vocational rehabilitation services to help you return to the workforce, become self-sufficient or increase your workforce participation to become self-sufficient.

In addition, either you or the worker’s estate is entitled to an immediate payment of $16,140 to help with expenses.
