The counterfactual is always very difficult. Certainly we can say that the dramatic supports being provided to households and businesses in Canada and other parts of the world are one reason the global demand is as strong as it is now. It stands to reason that had those supports not been as generous, the economic consequences of the pandemic would have been much worse for a broad range of Canadian firms and households.
Would the recession have been more prolonged or deeper? I can conjecture and say yes, but the question, to my mind, is more whether something needed to be done. Something was done. Was the right amount or the right thing done, given our understanding of the situation now, relative to the understanding of the situation at the time? Of course, those aren't necessarily the same thing.
