The criteria that give a view that it's a responsible track are things like Canada maintaining its AAA bond rating, right now. The debt-to-GDP ratio that Canada has, while it may increase from its GDP of 42% and change, is on track to go down to 39% in the medium term. Also, there is the view of the IMF, which recently reviewed Canada and said that there remains fiscal room.
For a number of reasons, briefly, I think there remains room to deal with different shocks. It's worth testing how much room there is, and the PBO can absolutely conduct that type of scenario analysis, such as, “At what point will we get into deeper trouble?”
