Statistics Canada reported that the year-over-year change in the All-Items Consumer Price Index for P.E.I. was 6.3 per cent in August 2021. The monthly increase was 0.3 per cent. This compares to 4.1 per cent year-over-year and 0.2 per cent monthly increases for Canada. Leading contributors to year-over-year price increases for P.E.I. were gasoline (37.2%), followed by fuel oil and other fuels (61.5%), homeowners' replacement cost (20.0%), purchase and leasing of passenger vehicles (7.2%), and rent (7.9%). These increases were partially offset by year-over-year declines for telephone services (-13.1%), mortgage interest cost*, women's clothing (-6.4%), recreational equipment and services excluding recreational vehicles (-2.3%), and preserved fruit and fruit preparations (-8.4%).

The monthly change for P.E.I. in August 2021 was 0.3 per cent. Higher prices for traveler accommodation (9.7%), inter-city transportation (27.5%), homeowners' replacement cost (1.5%), fuel oil and other fuels (2.2%), and fresh or frozen chicken (12.9%), were mostly offset by lower prices for travel tours*, children's clothing (-7.5%), preserved fruit and fruit preparations (-8.4%), telephone services (-2.0%), and household appliances (-1.9%).

Nationally, the All-Items Consumer Price Index rose 4.1 per cent on a year-over-year basis in July, up from a 3.7 per cent increase in July. This was the fastest year-over-year increase since March 2003. The increase in prices mainly stems from an accumulation of recent price pressures and from lower price levels in 2020. On a monthly basis, the CPI rose 0.2 per cent in August.

Year over year, prices rose at a faster pace in August than in July in every province ranging from 2.9 per cent in Saskatchewan to 6.3 per cent in Prince Edward Island. Compared to July, year over year prices rose faster August in four of the eight major components (food; household operations, furnishings and equipment; transportation; tobacco products and recreational cannabis). Year over year, prices for gasoline rose 32.5 per cent in August, mainly driven by lower production from oil-producing countries compared with pre-pandemic levels. Also contributing to the year-over-year increase were the low price levels observed in August 2020. The homeowners' replacement cost index, which is related to the price of new homes, continued to trend upward, rising 14.3 per cent year over year in August—the largest yearly increase since September 1987. This was the fourth consecutive month of double-digit price growth.


Impact of COVID-19 on the August CPI


Base-year effects and the CPI

In spring 2020, the global economy was dramatically affected by the COVID-19 pandemic, and Canadian consumers experienced a significant decline in prices from February to April 2020. Headline consumer inflation slowed from +2.2 per cent in February 2020 to 0.9 per cent in March and -0.2 per cent in April, the largest two-month slowdown in year-over-year CPI growth since 1992. As the economy began to recover in June 2020, prices began to recover as well. However, prices remained relatively flat in August 2020, creating an upward base-year effect, widening the gap between prices from August 2020 to August 2021, increasing the pace of inflation.

This publication explores the sources of pandemic-related price change and the ongoing impact of base-year effects on the headline CPI.
