I'm happy to.
These examples are often quite difficult, but to make it concrete, if you were to think of a parent whose child had received a diagnosis of cancer, that would be deemed a life-threatening illness and signed off by a specialist, and it would be an appropriate reason to begin benefits for that parent so that the parent could spend time with the child going through treatments and so on.
If, in those circumstances, the parent were, for example, to be in a car accident and need to take treatment, either hospitalization, recovery and so on, that parent could suspend the benefits for parents of critically ill children, which last up to 35 weeks to care for the child, take up to 15 weeks of sickness benefits, and then return to the benefits for parents of critically ill children, so that in total that parent could receive up to 50 weeks of benefits. If, during that period, the child's care was at a critical stage where the child needed a parent to be with him or her, the parents of critically ill children benefits are also shareable between the parents.
Essentially, I hope that's an example that demonstrates the flexibility we're trying to bring to the program in what are truly difficult circumstances.
