The Ontario government debt has been a pressing concern for many years. As of 2020, the province's net debt stood at over $340 billion.
This staggering figure has significant implications for the province's finances and the taxpayers who foot the bill. The debt has been growing steadily over the years, with a notable increase in the past decade.
The Ontario government's debt-to-GDP ratio is also a cause for concern, currently standing at over 40%. This means that for every dollar the province earns, it owes almost half a dollar in debt.

History and Causes
The history of Ontario's government debt is a complex one, but let's break it down. Health and education together account for more than 50% of Ontario's spending, with a combined total of $61.3B and $29.1B, respectively.
Tax cuts and incentives to high-income earners during the 1990s reduced government revenues, setting the stage for future financial challenges. Ontario's budget surplus in 2007-2008 quickly turned into a $19 billion deficit by 2009-2010 due to the Great Recession's impact on the manufacturing sector.
The Great Recession had a significant impact on Ontario, and the government's response to it has contributed to the province's debt. Ontario government's direct subsidies to corporations average $2.7 billion per year over the five years to 2011.

History

The history of this topic is complex and multifaceted.
The first recorded instances of this phenomenon date back to ancient civilizations, where it was often associated with social and economic inequality.
In many ancient societies, certain groups were denied access to basic necessities like food, water, and shelter, leading to widespread suffering and social unrest.
The concept of scarcity has evolved over time, with different societies and cultures developing unique perspectives on its causes and effects.
In some cultures, scarcity was seen as a natural part of life, while in others, it was viewed as a moral failing or a result of poor governance.
One notable example is the Great Depression of the 1930s, where economic scarcity led to widespread poverty and desperation.
Economic policies and social programs were implemented to alleviate the suffering, but the effects of scarcity were still felt for generations to come.
Today, we continue to grapple with the consequences of scarcity, from food insecurity to economic inequality.
The legacy of scarcity continues to shape our world, influencing everything from politics to personal relationships.

Causes

The causes of debt in Ontario are complex and multifaceted. One major contributor is the significant spending on health and education, which together account for over 50% of the province's budget, totaling $61.3B and $29.1B respectively.
The 1990s saw tax cuts and incentives aimed at high-income earners, which had a negative impact on government revenues. This reduction in revenue made it harder for the government to manage its finances.
The Great Recession of 2008 had a devastating effect on Ontario, particularly its manufacturing sector. The province's budget surplus in 2007-2008 quickly turned into a $19 billion deficit by 2009-2010.
Direct subsidies to corporations average $2.7 billion per year over the five years to 2011, which has been argued to contribute to increased debt rather than widespread economic growth or new jobs.
Domestic and International
The amount of borrowing in the Canadian dollar market has fluctuated over the years, with a high of $39.1 billion in 2020-21 and a low of $15.4 billion in 2007-08.

In 2024-25, Ontario's total long-term borrowing is forecast to be $37.5 billion, with $25.3 billion borrowed in the Canadian dollar market.
The Canadian dollar market borrowing has been steadily increasing since 2010-11, when it was $23.5 billion.
In contrast, foreign currencies borrowing has seen a decline in recent years, with a low of $3.7 billion in 2022-23.
Here's a breakdown of the total borrowing in Ontario over the years:
Debt Breakdown
Ontario's debt breakdown is a complex issue, but let's take a closer look at the numbers. As of March 31, 2018, the majority of Ontario's debt was issued in Canadian currency, making up 83.1% of the total debt.
The breakdown of Ontario's debt is as follows:
The majority of the debt is held in Canadian dollar public bonds, making up 74% of the total debt.
Breakdown
As of March 31, 2018, the breakdown of Ontario's debt is quite staggering. The majority of the debt (83.1%) was issued in Canadian currency.
The breakdown of Ontario's debt is as follows:
- Canadian Dollar Public Bonds: $259.4B (74%)
- Foreign Currency Bonds: $56.4B (16%)
- Canadian Dollar Treasury Bills: $18.9B (5%)
- Canadian Dollar Non-Public Debt: $11.4B (3%)
- US Dollar Commercial Paper: $2.6B (1%)
The Liberal government of Premier Kathleen Wynne projected a $600-million surplus in 2017–2018, but instead posted a 3.7 billion dollar deficit. This was due in part to the sale of Hydro One shares.
Cost
The cost of debt is a significant expense for Ontario, making up a substantial portion of its annual expenses. Ontario's estimated cost of borrowing for 2024–25 remains at 4 per cent, as long-term rates have remained within the forecasted range.
A one percentage point change in interest rates either up or down from the current interest rate forecast is estimated to have a corresponding change in Ontario's borrowing costs of approximately $700 million in the first full year. This highlights the importance of effective interest rate risk management strategies to minimize the impact of changing market conditions.
Chart 4.7 shows the average borrowing rates on debt issued in 2023–24 and the forecasts used to estimate the cost of borrowing for 2024–25 and the medium-term outlook. The forecast rates remain unchanged from the 2024 Budget.
Ontario's borrowing costs for 2024–25 are now estimated to be 3.94 per cent, six basis points lower than forecasted in the 2024 Budget. This reduction in borrowing costs is a positive development for Ontario's finances.
A one percentage point change in interest rates, either up or down from the current interest rate forecast, is estimated to have a corresponding change in Ontario's borrowing costs of approximately $0.8 billion in the first full year. This is a significant impact that highlights the importance of monitoring interest rates closely.
Here is a comparison of the forecasted interest and other debt servicing charges (IOD) expense for Ontario:
The effective interest rate on Ontario's total debt has been steadily decreasing over the years, from 10.9 per cent in 1990–91 to 3.4 per cent in 2023–24.
Term
The term of debt is a critical aspect of Ontario's financial situation. Ontario has continued to extend the term of its debt when investor demand allowed, to reduce future refinancing risk.
This strategy has been successful in creating flexibility for managing its large borrowing program and debt portfolio. The impact on the government's finances in the short term and medium term has been lessened due to the extension of the term of debt.
Since 2010-11, Ontario has issued $147 billion of bonds, or almost a third of total debt, with maturities of 30 years or longer. This includes $9.8 billion so far in 2024-25, and $12.7 billion in 2024-25, according to different reports.
The average term of Ontario's debt portfolio has been extended from 9.7 years in 2009-10 to 11.7 years in 2024-25. The weighted-average borrowing term for 2024-25 was 15.7 years as of October 7, 2024.
Here's a breakdown of the weighted-average borrowing term and debt portfolio average term over the years:
Risks and Consequences
In 2012, Moody's Investors Service downgraded Ontario's rating from Aa1 to Aa2, citing a growing debt burden as a major concern.
The agency changed its outlook on this rating from "stable" to "negative" in April 2018, stating its expectation that spending pressure will challenge the province's ability to sustain balanced fiscal results across multiple years.
Ontario had a 42.9% probability of defaulting on its debt obligations in the following 10-20 years, which is higher than any other province.

Risks and Consequences
In 2012, Moody's Investors Service downgraded Ontario's rating from Aa1 to Aa2, citing "growing debt burden" as a major concern.
The Province of Ontario has a significant debt burden, with a 42.9% probability of defaulting on its debt obligations in the following 10-20 years, according to the Provincial Solvency and Federal Obligations study.
This high probability of default is a major concern, as it could have severe consequences for the province's economy and citizens.
The interest on debt-to-revenue ratio is a key indicator of a province's financial health. In 2024-25, Ontario's interest on debt-to-revenue ratio is forecast to be 6%.
Here's a breakdown of Ontario's interest on debt-to-revenue ratio over the years:
This table shows a steady decline in Ontario's interest on debt-to-revenue ratio over the years, but it's still a concern that it's forecast to be 6% in 2024-25.
Average Annual Rate Forecast
The Average Annual Rate Forecast is a crucial aspect of understanding the risks and consequences of Ontario's debt. As of September 30, 2024, the effective interest rate (calculated as a weighted average) for fiscal year-end is forecast to be 3.4 per cent on Ontario's total debt.
This rate has been steadily decreasing over the years, from 10.9 per cent in 1990-91 to 3.4 per cent in 2024-25. It's essential to note that this rate can have a significant impact on the province's finances.
The forecast for the next few years shows a slight increase, with a predicted rate of 3.4 per cent in 2024-25 and 3.4 per cent in 2025-26. However, the interest on debt-to-revenue ratio is forecast to be 6 per cent in 2024-25, which is a significant concern.
Here's a breakdown of the forecasted interest rates for the next few years:
It's essential to monitor these rates and ratios to understand the potential risks and consequences for Ontario's finances.
Debt Reduction
The Ontario government has been working to reduce its debt burden, and it's making progress. In 2012, the Liberal Party commissioned the Drummond Report, which proposed measures to reduce the province's debt level.
One of the key measures proposed was debt reduction through spending cuts. The Progressive Conservative Party also proposed eliminating the deficit and reducing debt through similar means in their 2014 election platform. However, not all parties agree on the best approach to debt reduction.
The government has been committed to reducing the debt burden and putting Ontario's finances back on a more sustainable path. As part of this effort, Ontario has maintained its targets set in the 2023 Budget, and the 2024–25 net debt-to-GDP ratio is now forecast to be 37.8 per cent, a decrease of 1.4 percentage points from the forecasted 39.2 per cent in the 2024 Budget.
Here's a breakdown of Ontario's progress on debt sustainability measures:
The government's strategy is working, and Ontario's net debt-to-GDP ratio is now forecast to be 37.9 per cent in 2025–26 and 37.5 per cent in 2026–27. This ratio measures the relationship between a government's obligations and its ability to meet them, indicating the burden of government debt as a share of the economy.
Financial Management
Ontario's net debt has been steadily increasing over the years, reaching $460,753 million by 2025-26. This is a significant amount, and it's essential to understand how the government manages its debt.
The Ontario government aims to maintain a level of cash reserves that balances potential holding costs with the need to have adequate funds to meet its financial obligations. As of 2024-25, the government's cash reserves are projected to be $43.4 billion.
Table 4.4 shows the breakdown of Ontario's publicly held debt, which includes bonds, treasury bills, and commercial paper. The total publicly held debt increased from $406,139 million in 2020-21 to $483,642 million in 2025-26.
Here is a breakdown of the publicly held debt:
The government's net debt includes both publicly held debt and non-public debt. As of 2025-26, the net debt is projected to be $460,753 million.
Financial Data
As of 2024-25, Ontario's publicly held debt stands at $483,642 million, with a total debt of $489,806 million and a net debt of $460,753 million.
The average term of Ontario's debt portfolio has been extended from 9.7 years in 2009-10 to 11.7 years in 2024-25, with a weighted-average borrowing term of 15.7 years as of October 7, 2024.
Here's a breakdown of Ontario's debt portfolio average term in recent years:
Consolidated Financial Tables
The Consolidated Financial Tables provide a detailed look at Ontario's financial situation. The tables are divided into several sections, including Net Debt and Accumulated Deficit.
Total Publicly Held Debt has been steadily increasing, reaching $483,642 million in 2024-25. This includes debt issued by Ontario and other government organizations.
The Gross Debt, which includes both publicly and non-publicly held debt, also shows a significant increase, reaching $489,806 million in 2024-25. This is due in part to the growth of non-public debt.
Non-public debt has been decreasing, from $9,318 million in 2020-21 to $6,164 million in 2024-25. This is a positive trend for Ontario's financial health.
The Accumulated Deficit, which is the total amount of money owed by the government, has been increasing steadily, reaching $264,914 million in 2024-25. This is a significant concern for Ontario's financial situation.
Here is a breakdown of the Net Debt and Accumulated Deficit over the past few years:
These numbers highlight the need for Ontario to address its growing debt and deficit.
4.8: Weighted-Average Term
The weighted-average term of Ontario's debt portfolio has been extended over the years. This extension has reduced refinancing risk and protected the IOD forecast against future interest rate increases.
Since 2009-10, the weighted-average term of Ontario's debt has increased from 8.1 years to 15.7 years in 2024-25. This is a significant increase, indicating that Ontario has successfully extended the term of its debt.
The debt portfolio average term has also increased, from 9.7 years in 2009-10 to 11.7 years in 2024-25. This suggests that Ontario's debt is becoming more long-term in nature.
Here's a breakdown of the weighted-average borrowing term and debt portfolio average term over the years:
The extension of the weighted-average term of Ontario's debt has provided flexibility in managing its large borrowing program and debt portfolio.
4.12: Net Revenue-to-Revenue
In Ontario, the net debt-to-revenue ratio is a significant financial metric that indicates the province's ability to manage its debt. According to the forecast, Ontario's net debt-to-revenue ratio is expected to be 202 per cent in 2024–25.

The net debt-to-revenue ratio has been steadily increasing over the years, with some fluctuations. For instance, in 1990–91, the ratio was 78 per cent, and by 2011–12, it had increased to 208 per cent.
Here's a breakdown of the net debt-to-revenue ratio for Ontario from 1990–91 to 2024–25:
The forecast suggests that the net debt-to-revenue ratio will continue to increase, reaching 202 per cent in 2024–25.
Bond Program
The Ontario government's bond program plays a significant role in managing the province's debt. Ontario's long-term borrowing requirement for 2024–25 is now forecast to be $37.5 billion.
The government plans to finance most of its borrowing program in the long-term public markets in Canada and internationally. This strategy helps reduce Ontario's overall borrowing costs by diversifying its investor base.
As of October 15, 2024, $31.4 billion, or 84 per cent, of this year's long-term public borrowing has been completed. Ontario's target range for domestic borrowing remains unchanged at 75 to 90 per cent of borrowing completed for the 2024–25 fiscal year.

Foreign currency borrowing is also a significant component of Ontario's bond program. To date, approximately 80 per cent of 2024–25 long-term borrowing was completed in Canadian dollars, through 24 syndicated issues, and two Green Bonds.
Ontario's Green Bond Program is a core component of its Sustainable Bond Framework. Since 2014, Ontario has issued 18 Green Bonds, totaling $21.5 billion, with $16.75 billion outstanding.
Here are some key facts about Ontario's Green Bond Program:
The government plans to continue its leadership in the Canadian dollar Green Bond market, subject to market conditions.
Outlook and Scenarios
The Ontario government debt is a complex issue, and understanding the different scenarios can be helpful in grasping the situation. The planning projection for long-term borrowing in 2023-24 is $42.6 billion.
Looking ahead, the planning projection for 2024-25 is $37.5 billion, with a slight decrease from the previous year. The slower growth scenario for 2024-25 is actually a bit higher at $39.7 billion, indicating a possible increase in borrowing.
In the faster growth scenario, borrowing is expected to decrease significantly, with $35.0 billion in 2024-25 and $27.3 billion in 2025-26. This suggests that a faster economic growth would lead to reduced government borrowing.
Here are the projected borrowing amounts for the planning projection and slower growth scenario for the next few years:
The faster growth scenario, on the other hand, projects a significant decrease in borrowing, with $25.9 billion in 2026-27. This indicates that a faster economic growth would lead to reduced government borrowing.
