Canada's federal government is heading into its next budget with a fiscal picture that leaves little room for big ideas. According to a new analysis from KPMG Canada, the country is on track for a deficit of roughly CA$65 billion in fiscal 2026-27, with only a modest improvement to about CA$60 billion the following year. That tight math, the firm argues, makes a sweeping rewrite of the tax system unlikely—and points instead to smaller, more targeted measures like tax simplification.
What the numbers show
A deficit is the amount by which government spending exceeds revenue in a given year. When Ottawa runs a deficit, it must borrow the difference, typically by issuing Government of Canada bonds. KPMG's projection of a CA$65 billion shortfall is substantial, and the fact that it barely narrows in 2027-28 suggests the pressure on federal finances is not a one-off blip.
The firm's note, released ahead of Thursday's federal budget, highlights that expectations for tax changes have been building. But with deficits this large, the government has limited fiscal firepower to fund major reforms. Instead, KPMG expects Ottawa to focus on smaller fixes—such as simplifying the tax code—rather than a system-wide overhaul that would require significant revenue offsets or spending cuts.
Why deficits matter to investors
For everyday investors, the size of the deficit matters beyond the political debate. When the government borrows more, it issues more bonds, which can affect bond prices and yields. KPMG notes that investors are becoming more sensitive to persistent inflation and rising deficits, which can translate into higher borrowing costs for the government over time.
That dynamic is worth watching, especially given the broader economic backdrop. Canada's economy has shown signs of strain, with recent data pointing to stalled growth. The Bank of Canada has been navigating a delicate path, and some economists see the central bank nearing the end of its rate-hiking cycle. If deficits keep rising while inflation remains sticky, it could complicate the Bank of Canada's efforts to manage price stability.
What this means for your money
For most Canadians, the practical takeaway is that major tax reform—like a broad overhaul of income tax brackets or a shift in the GST—is unlikely in the near term. Instead, expect incremental changes: tweaks to credits, deductions, or rules that aim to simplify compliance without dramatically changing the overall tax burden.
Investors should also keep an eye on the bond market. If deficits stay large and borrowing costs rise, it could put upward pressure on interest rates, which affects everything from mortgage rates to the returns on fixed-income investments. At the same time, a government focused on smaller fixes may be less likely to introduce disruptive tax changes that could affect corporate earnings or investment decisions.
Context: Canada's fiscal and economic landscape
The KPMG projection comes as Canada's economy has been struggling to gain momentum. Recent reports show the economy stalling, and manufacturing activity has been hit by tariff-related cost pressures. These factors weigh on tax revenues, making it harder for the government to close the gap between spending and income.
Provincial governments are also feeling the pinch. Ontario, for example, has pushed back its balanced-budget target to 2029-30 as deficits rise, according to RBC. That suggests the fiscal squeeze is not just a federal issue—it's a broader trend across the country.
At the same time, the Bank of Canada's policy path remains a key variable. If the central bank is indeed near the end of its rate hikes, as some economists suggest, that could provide some relief on debt-servicing costs for the government. But if inflation proves stubborn, the Bank may need to keep rates higher for longer, which would add to the cost of carrying the deficit.
What to watch next
Thursday's budget will be the immediate focus. Investors will be looking for clues on how the government plans to address the deficit—whether through spending restraint, revenue measures, or continued borrowing. Also on the radar: any signals about tax policy changes, even if they are modest.
Beyond the budget, the trajectory of the deficit will depend on economic growth, inflation, and interest rates. A stronger economy would boost tax revenues and shrink the gap; a weaker one would do the opposite. For now, KPMG's numbers suggest that Ottawa's fiscal flexibility is limited, and that the era of big, bold tax reform is not on the horizon.
