| The Consumer Price Index (CPI) rose 2.4% on a year-over-year basis in December, following a 2.2% increase in the prior two months.
The year-over-year acceleration in the all-items CPI was driven by the temporary Goods and Services Tax (GST)/Harmonized Sales Tax (HST) break that began on December 14, 2024. This resulted in monthly declines for the exempt goods and services, which have now fallen out of the year-over-year movement, putting upward pressure on headline CPI growth.
The headline CPI accelerated, but the year-over-year decline in gasoline prices in December moderated it. Excluding gasoline, the CPI rose 3.0% in December, following a 2.6% increase in November.
The CPI fell 0.2% month over month in December. On a seasonally adjusted monthly basis, the CPI increased 0.3%.
Various indexes were affected by the GST/HST exemption in December 2024, including restaurant food, alcoholic beverages, toys, games and hobby supplies, children’s clothing and some grocery items, such as potato chips and confectionery.
Year over year, higher restaurant prices were the largest contributor to faster all-items CPI growth in December 2025. Prices for food purchased from restaurants rose 8.5% in December, up from 3.3% in November. Prices for alcoholic beverages served in licensed establishments (+6.5%) and purchased from stores (+5.6%) also rose faster in December.
Prices for toys, games (excluding video games) and hobby supplies rose 7.5% in December, after a 0.5% decline in November. Additionally, prices for children’s clothing accelerated in December (+4.8%) compared with November (+2.4%).
Year-over-year price growth also picked up for potato chips and other snack products (+7.9%) and confectionery (+14.2%).
Despite being unchanged month over month, prices for food purchased from stores rose 5.0% year over year in December. Coffee (+30.8%) and fresh or frozen beef (+16.8%) remained the largest contributors to the increase. |
