Canada’s debt problems are approaching the point of no return, likely cementing the end of the low-rate era. The Parliamentary Budget Officer (PBO) broke down federal spending and revenue for 2026-27. While critics focus on corporate welfare and loose spending, the real issue is much worse. The data reveals that over a quarter of revenue is already allocated to debt and elderly benefits. That amount is set to surge to over a third of all revenue by the end of the 2020s, suggesting a structural deficit and the end of Canada’s low-rate era.
Credit Is A Market, Rates Are Determined By Supply & Demand
First off, no person left behind—so let’s all get on the same page by reviewing how interest rates work. The Bank of Canada (BoC) uses policy to influence rates, but it’s ultimately determined by the market. Rates move lower when there’s an excess of capital (supply) relative to borrowing (demand). They move higher when borrowing needs grow faster than the capital to lend. When everyone wants to lend you money, you pay less. If no one wants to lend you money, returns (interest paid) need to rise to motivate.
The concept applies to borrower quality. The federal government pays the lowest rate, since they issue the currency, it’s kind of hard to default. This establishes a benchmark rate used to determine borrowing costs for us schmucks. Lower-quality borrowers pay more, as they have to provide incentives to cover risk and reduced liquidity.
Public borrowing doesn’t just impact the government costs, but the impact flows downstream. This is part of the reason government-backed loans may reduce the cost to certain borrowers, but that premium is sent downstream to those not blessed by taxpayer subsidies.
Monetary policy can also create temporary relief. However, that scale creates an even bigger risk of failure—as I previously explained to Parliament’s finance committee. However, you’ll only need the 10,000 ft view of credit markets to understand today’s problem.
Congrats! You’re now more informed than most policymakers on the topic. On to the Spring Update!
Canada To Spend Over 1 In 10 Dollars On Interest Payments
PBO data shows the Federal government has $502.8 billion in spending authorities for 2026-27. Out of that, the report shows $272.4 billion is statutory authorities, already authorized spending under existing legislation. The remaining $230.4 billion is voted authorities, requiring a vote. Not a major hurdle for the current government since they have a majority mandate secured.

Boring, but important to put the scale of debt in context. Public debt charges are estimated to represent $53.7 billion of spending, just over 1 in 10 dollars (10.7%)—up from 9.5% ($4.7 billion) from a year prior. Nearly a tenth of government revenues has already been spoken for by past government spending.
Even more remarkable is the fact that it’s not stopping there. The PBO’s forecast shows the share of revenues spent on interest will hit 13.2% of revenues by 2030-31. Almost 1 in 8 dollars of that is just to service debt. Even if policymakers didn’t spend another dollar, Canadians are projected to spend 2.1% of GDP to worship service the debt.
To understand the scale, let’s look at the Canada Health Transfer. This is the program that distributes funds across provinces to ensure universal access. It’s the largest federal transfer program, estimated to hit $57.4 billion in 2026-27, up 5% (+$2.7 billion) from last year. That’s only 0.7 points higher than the amount used by debt charges. If healthcare scales as a consistent share of the budget, it falls behind debt charges by 2030.
“Public debt charges have increased significantly over the last three years due to a substantial increase in the stock of public debt over the course of the pandemic combined with subsequent higher effective interest rates,” writes the PBO.
They also don’t see any improvement: “PBO anticipates that public debt charges will continue to increase both as a share of government revenues and as a share of nominal GDP…”
Canada’s Debt & Elderly Benefits To Consume A Third of Revenue
Debt charges aren’t even the largest liability Canada has baked into its economy. That honor goes to Canada’s rapidly aging population. The PBO specifically cites Old Age Security (OAS) as a concern, pushing elderly benefits to $89.3 billion in 2026-27, up 7.5% (+$6.2 billion). That liability hits $108.5 billion by 2030-31, making it ~60% larger than the Canada Health Transfer.

The PBO warns that OAS is “currently the largest federal program,” with elderly benefits accounting for “approximately one in every six dollars of federal spending.” A growing senior population and inflation are driving the growth, they warn. That means higher inflation is tied to higher OAS liabilities, and higher rates mean higher debt charges. Well, $@$%.
The current estimate means that over 1 in 4 (27.7%) dollars are already spent on just debt charges and elderly benefits. By 2030-31, the Federal government estimates this will rise to over a third (35.2%). Canada wouldn’t even qualify for a mortgage with that level of liabilities.
Canada’s Deficit Appears Structural, Amplifying Vulnerability
The combination all but guarantees that Canada’s deficit is now structural. A structural deficit isn’t just a short-term imbalance, but one baked into the system. It doesn’t matter if the economy is booming or in recession, policymakers need credit.
Canada’s highly indebted households already mean the economy is vulnerable to a shock. Ottawa’s fiscal position amplifies that risk. As policymakers are increasingly exposed to fixed costs, it becomes much harder to pretend every crisis is avoided with more debt. It’s even harder to pretend that “affordability” measures that resemble bailouts are free.
Much of the debt accumulated was presented as affordability help for households and businesses. Ironically, it’s doing the opposite over the long term. It’s hard to see a wave of investors scrambling for lower returns, dedicating capital at a pace that outpaces our persistent borrowing needs. Even if a guy in a slick suit claims those investors will be coming—we just need to buy a Monorail first.
