Trade Uncertainty, Energy Volatility, Debt Load Among Key Risks
This GRI analysis of the 2026 Ontario Budget reviews key elements of the budget through a financial sector lens, and highlights associated risks including trade uncertainty, geopolitical shocks and fiscal performance. The budget projects a deficit of $13.8 billion for 2026–27, with a return to a modest surplus by 2028–29.
Key risks identified include:
- Revenue sensitive to growth: A $15.8 billion range in projected tax revenue underscores how dependent the fiscal outlook is on nominal GDP performance.
- Interest rate exposure: With total debt exceeding $400 billion, a 100-basis-point increase in borrowing costs would add roughly $870 million in annual costs.
- Demand-driven spending pressures: Healthcare, social assistance and education costs can escalate quickly, with relatively small changes translating to hundreds of millions in additional expenditures.
- Trade uncertainty: A severe downside scenario involving CUSMA withdrawal and higher U.S. tariffs would materially weaken growth and widen deficits.
- Geopolitical and inflation risks: Escalating global conflicts could drive energy prices higher, weaken the Canadian dollar and push inflation above forecast.
Market and sector-specific vulnerabilities, including a correction in AI-driven investment and ongoing housing market softness, could also dampen growth and reduce revenues. While the budget is based on conservative planning assumptions, the province’s fiscal trajectory is highly contingent on external conditions like trade, interest rates and geopolitical stability. Overall, spending and revenue projections reflect an effort to balance near-term stimulus with longer-term fiscal discipline.
