Statistics Canada says the annual pace of inflation climbed in December to its highest rate since 1991.
The agency says the consumer price index in December was up 4.8 per cent compared with a year ago.
The reading compared with a year-over-year increase of 4.7 per cent in November.
Driving the faster pace of price growth in December were higher year-over-year prices for food, passenger vehicles and housing.
Statistics Canada says that excluding gasoline prices from its calculations, the consumer price index would have been up year-over-year in December by four per cent.
Prices at the gas pumps were up 33.3 per cent year-over-year in December compared with a 43.6 per cent annual increase in November as tightening of public health restrictions related to the Omicron variant weighed on demand.
December marked nine months in a row that headline inflation has come in above the Bank of Canada's target zone of between one and three per cent.
The country hasn't seen a streak that long since before the central bank began targeting inflation at two per cent in the midpoint of its comfort range.
CIBC senior economist Andrew Grantham says the streak may not be over, which could cause some concern within the Bank of Canada.
He writes in a note that rising energy prices, supply chain issues affecting food costs and jumps in house prices suggest headline inflation could grind higher still before cooling around springtime.
The Bank of Canada has said that it would act to stop runaway inflation and is scheduled to make a rate announcement next week.
The average of the three measures for core inflation, which are considered better gauges of underlying price pressures and closely tracked by the Bank of Canada, was 2.93 per cent for December, up from the 2.73 per cent reported in November.
The average was last that high in September 1991.
