According to what I know of the current system, if someone has a disabled child who is 24 years of age or older, they receive all the benefits for disabled children. The new special benefits, on the other hand, will aim to protect parents' employment at specific times, during crisis periods, when a child is gravely ill or has suffered a serious accident.
Is that the same thing? A disability requires long-term daily care. The benefits are intended for times of crisis. I don't think that employment insurance is the best tool for helping those families.
