Grocery inflation in Canada surged again in November as the price of basics like bread, eggs and dairy products shot up.

Prices for food purchased from stores rose 11.4 per cent last month compared with a year ago, up from an 11 per cent gain in October, according to Statistics Canada numbers released Wednesday.

Grocery prices have now risen at a faster pace than overall inflation for 12 months in a row.

The country's annual inflation rate edged down slightly in November to 6.8 per cent.

Coffee and tea prices were up 16.8 per cent in November while items such as butter climbed 23.1 per cent, eggs rose 16.7 per cent and bread, rolls and buns were up 18.2 per cent.

Other items to jump in price include sugar and syrup, up 18.8 per cent year-over-year, pasta products up 17.1 per cent, lettuce up 31.9 and flour and flour-based mixes up 20.5 per cent.

Rising grocery prices is a global phenomenon, with countries like France, Germany and the U.K. posting even higher food inflation rates than Canada last month, said Sylvain Charlebois, professor of food distribution and policy at Dalhousie University.

Still, much of Canada's food is produced domestically, and prices are increasing due to a host of factors including higher labour, input and energy costs, he said.

"A lot of collective agreements are being negotiated with wage increases of over five per cent and that's putting pressure on the cost to produce anything," Charlebois said. "One example is the packaging that food companies use. We've seen prices of packaging like egg cartons go up significantly."

It could be some time before Canadians see food prices stabilize, he added.

"We're still in this for the next four to six months," Charlebois said. "We are expecting things to come down in the spring."
