reconsideration
If you do not agree with a decision that the Workplace Safety and Insurance Board (WSIB) makes, you can ask them to review and change it. This is called asking for a reconsideration. For example, you might disagree with a decision about qualifying for benefits, how much money you get, or how long you can get benefits.
Usually, the person who made the decision reconsiders it. But sometimes the person’s manager does.
When you ask for a reconsideration, you can give new information and documents that the WSIB did not have when they made the original decision.
