Thanks so much for the question.
Certainly, when it comes to debt and deficits, the federal government does not exist alone. It exists within the Canadian economy, across from other large sectors in the economy, and deficits and debt are fungible. In essence, they can move between sectors. In this case, the federal government took on a massive deficit in this year and what that did was create smaller deficits and in fact some surpluses in other sectors of the economy. For every deficit there's a surplus of equal value in another sector of the economy.
The federal government could have decided to spend none of this money. It could have decided to have no CERB, no support for business, no support for provinces and no support for health care and individuals. What would have occurred in that case is that those deficits would not have occurred on the federal books. They would have occurred on provincial government books as they covered health care costs. They would have occurred on household books that incurred deficits because they lost work but still had expenses, or on business books.
Despite the federal and provincial governments' efforts, we've nonetheless seen increases not only in federal debt but also in household and corporate debt at the same time. In fact, the household and corporate sectors are far more leveraged than the federal government is. If we were to see interest rate increases, they would certainly hit the federal government, but they'd hit the household and business sectors much harder. Not only do they pay higher interest rates, but they have a lot more debt.
I think it's worth understanding the federal government and its deficits not on their own, but by how it and those deficits relate to other sectors in the economy.
