Data gaps, yes, there are. As you proceed and gather data, you could certainly delve into them, but tread very carefully. It's very difficult to know exactly what you're getting when you're looking at data, so you have to ask lots of questions about exactly how it was formulated.
On the five weeks, I don't know what your consultations led to. It's not my area of expertise at all. However, there's no doubt in my mind, and I have data to back it up, that the more vulnerable you are, the more likely you are to not be eligible for EI. The addition of five more weeks of EI added benefits for those who are already getting EI, so I don't think you can construe that as helping the people who are most vulnerable, because they're the ones who are excluded.
And you're right, you have to worry about how much money is being spent and you have to make sure it's spent appropriately. I think the $57 billion, if that's the right figure, or the $54 billion, illustrates how there has always been money to spend; we just chose not to spend it on these populations. Your job as members of Parliament is to decide how the money is to be spent.
