Canadian inflation stabilizes – for now

Carbon tax issues still pose an inflationary risk
Canada’s federal government temporarily cut the carbon tax on consumers to zero in April of 2025. The effects on the consumer price index were seen immediately. At the time, Statistics Canada revealed that “gasoline led the decline in consumer energy prices, falling 18.1% year over year in April, following a 1.6% decline in March. The price decrease in April was mainly driven by the removal of the consumer carbon price. Year over year, prices for natural gas fell 14.1% in April, after a 6.4% gain in March. The removal of the consumer carbon price contributed to the decline in April.” As can be seen in the accompanying graph, the annual pace of overall inflation has remained inside a 1.7% to 2.4% range since that time. However, the delayed 2025 Federal Budget outlined a plan to increase the carbon tax at the industrial level to $170 per tonne by 2030.
The combination of rising corporate taxes, which will have to be passed along to consumers, and the elimination of the ‘year-over-year’ effect of the reduction of the consumer carbon tax will heavily influence overall inflation over the next six months. Further, the statistics agency continues to highlight the uncertainty over tariffs and their embedded influence on consumer prices going forward. The three Bank of Canada core inflation measures remained elevated in October, ranging from 2.7% to 3.0%. Any material resurgence in broader inflation would be viewed as sufficient rationale for the Bank of Canada to end the current cycle of lowering interest rates.
U.S. markets well ahead on first anniversary of presidential election
A contentious U.S. presidential election on November 5, 2024, was followed by a series of dramatic international developments in global trade and commerce. Nevertheless, while it has been a bumpy ride, the U.S. equity market has turned in an extraordinary performance over the past 12 months. After an initial move to a new high on February 19, the benchmark S&P 500 saw a correction that took the index back down 18.9% by the close on April 8. Still, this down-beat was fully recovered by June 27.
Eventually the index reached a new all-time, inter-day high of 6,920.3 on October 29, 2025. This level marked a 21.1% advance from the closing level established the day before the election and a cumulative 92.6% advance from the end of the bear market on October 12, 2022, seen during the previous administration.
Longer View
Hundreds of billions of dollars have been invested in artificial intelligence with the goal of boosting productivity, enhancing quality of life, and improving health outcomes. These investments are poised to yield tangible benefits beginning in 2026, with positive impacts expected to unfold over the next decade.
As with any transformative shift, the early stages may bring discomfort and disruption. However, through thoughtful adaptation and strategic modifications, the advantages of AI integration will become increasingly clear. AI has the potential to reshape industries and daily life alike. Crucially, the productivity gains driven by AI should help ease labour inflation pressures and support stronger earnings growth.
As businesses become more efficient and individuals more empowered, the long-term economic and societal benefits could be profound.
