The federal government says it expects the heads of five of Canada's biggest grocery chains to attend a meeting in Ottawa on Monday to discuss ways to stabilize food prices.

The office of Industry Minister François-Philippe Champagne told CBC News it asked the CEOs of Loblaw, Sobeys, Metro, Costco and Walmart to attend in person.

"It's not okay that our biggest grocery stores are making record profits while Canadians are struggling to put food on the table," Trudeau told a press conference Thursday.

Karl Littler, senior vice president of public relations with the Retail Council, told CBC News Network's Power & Politics that grocers are also facing higher costs.

After spending months examining Canada's grocery sector, the bureau concluded it's mainly controlled by three domestic companies  — Loblaw, Metro and Sobeys owner Empire — along with foreign giants Walmart and Costco.

The release said the bureau would also be given the authority to take action against "collaborations that stifle competition and consumer choice, in particular situations where large grocers prevent smaller competitors from establishing operations nearby."
