Canada's federal government is preparing to deliver its budget next Thursday, but the wishlist of new spending and tax measures announced in recent months is already eating into the country's fiscal flexibility. According to a new analysis from Scotiabank Economics, the commitments made since the Spring Economic Update could add between CA$63 billion and CA$80 billion to Ottawa's tab over the budget horizon.
The estimate comes as Prime Minister Mark Carney's government prepares to lay out its fiscal plan. Scotiabank's research team, led by economist Rebekah Young, notes that the measures announced so far total roughly CA$63 billion, with the potential to reach CA$80 billion if the government adds further investment-focused tax breaks.
What's driving the higher costs?
The new commitments span a range of spending promises and tax measures that have been rolled out since the spring. While the government has framed these as investments in the economy, they come at a time when the federal budget is already under pressure from slower growth and higher debt-servicing costs.
Scotiabank argues that Canada's economy is holding up well enough to absorb some of the added spending. The bank expects the federal deficit to shrink into the mid-to-high 1% range of the economy's annual size over time, with the federal debt burden stabilizing about one percentage point higher than projected in the spring outlook. That suggests the fiscal deterioration, while real, is not catastrophic.
But the trade-off is clear. More public spending and tax breaks can add demand to the economy, which can keep inflation stickier than policymakers would like. That complicates the Bank of Canada's job as it tries to bring inflation back to its 2% target without choking off growth.
Why the bond market matters
Even if Ottawa's plans look manageable on paper, there are practical risks. Young noted that delays in implementing programs at home and rising global bond yields can quickly erode the government's flexibility. When global yields are already climbing, as they have been in recent months, additional Canadian borrowing can push domestic yields higher as well.
That dynamic is particularly important for households. When the government issues more bonds, investors often demand higher interest rates to lend for longer periods. Those government bond yields feed into many Canadian borrowing rates, especially fixed mortgage rates and other longer-term loans. So even without an immediate change in the Bank of Canada's policy rate, heavier federal borrowing can put upward pressure on the rates households end up paying.
For anyone with a fixed-rate mortgage or planning to renew one, this is a key channel to watch. The budget's size and the market's reaction to it could influence the direction of those rates in the months ahead.
What it means for investors
For investors, the budget is more than a political event—it's a signal about the country's fiscal trajectory and its implications for interest rates and inflation. If the government follows through with the upper end of the CA$80 billion estimate, bond markets may react by pricing in higher yields, which could ripple through the broader economy.
That said, Scotiabank's assessment suggests the situation is manageable, not alarming. Deficits are still expected to shrink, and the debt burden is projected to stabilize at a modestly higher level. The key risk is if inflation proves stickier than expected, forcing the Bank of Canada to keep rates higher for longer.
Investors should also keep an eye on how the budget interacts with global trends. Rising global bond yields, partly driven by inflation concerns and central bank policies elsewhere, can amplify the impact of Canada's own borrowing. As Canada's bond index shuffle shows, even technical factors in the bond market can move significant sums.
The budget will also be watched for any measures that could affect specific sectors, similar to how other countries have used budgets to target certain industries. For instance, Italy's budget targeted banks and energy firms with a one-off tax, while the UK doubled its bank surcharge in a recent budget. Canada's approach may differ, but investors should be alert to any sector-specific announcements.
Ultimately, the budget will be a balancing act. The government wants to deliver on its promises, but it must do so without spooking bond markets or reigniting inflation. For everyday investors, the takeaway is to watch the bond market's reaction and consider how any changes in yields might affect their own borrowing costs.
As the budget date approaches, expect more analysis from economists and market strategists. The numbers from Scotiabank provide a useful baseline, but the final budget could still surprise. Whether it comes in at the lower or higher end of the range will depend on the government's choices in the coming days.
