For more than a decade, Canadian governments have increasingly relied on borrowed money to fund their excessive spending habits. However, as debt has continued to pile up so have the costs associated with this debt—namely interest costs. A recent study shows that in some of the largest provinces, governments now spend nearly as much or more on debt interest costs than on K-12 education.

Since the 2008/09 financial crisis, governments across Canada have fallen into the habit of utilizing debt to fund their spending habits. For example, consider the federal government.

From 2008/09 to 2023/24, the federal government is projected to have run deficits every single year, with no interruptions. This has resulted in federal net debt (total debt minus financial assets) increasing by $603.6 billion (inflation-adjusted). Conversely, from 1996/97 to 2007/08, the federal government actually lowered its net debt by $348.1 billion (inflation-adjusted). Clearly, there’s been a shift in the government’s approach towards debt accumulation.

This is not simply a federal problem, as provinces have also seen their debt burdens rise as well. Cumulatively, provincial and federal net debt has increased by $1.0 trillion (inflation-adjusted) from 2007/08 to 2023/24.

Government debt carries costs, primarily in the form of the interest payments, which represent money that doesn’t go towards paying down the actual debt amount, nor does it go towards providing government services or tax relief. And since governments must utilize tax revenues to pay interest, taxpayers are ultimately on the hook for servicing government debt.

But how much do Canadians actually pay in debt interest costs?

Using data from the most recent fiscal updates, a new study compares combined (federal and provincial) debt interest costs for residents in three of the largest provinces (Ontario, Quebec and Alberta) with what those provinces expect to spend on K-12 education in 2023/24. The study utilizes combined debt interest costs because Canadians are ultimately responsible for interest costs incurred by both the federal government and the province in which they live. The following chart summarizes the comparisons from the study.

As is clear from the chart, combined interest costs for residents in these provinces are nearly as much or more than their province expects to spend on K-12 education in 2023/24. Specifically, combined interest costs are $31.5 billion for Ontarians, which is only $3.2 billion less than the province will spend on K-12 education in 2023/24. Combined interest costs for Quebecers ($20.3 billion) will actually exceed the $19.9 billion the province will devote towards K-12 education. And combined interest costs for Albertans are only slightly lower than the $8.9 billion that will be spent on K-12 education.

In other words, taxpayers in Ontario, Quebec and Alberta are paying nearly as much or more to service federal and provincial government debt than they are paying to fund K-12 education in their province. This budget season, it’s important to remember the costs associated with growing government debt.
