The National Post reports in its Friday edition that Prime Minister Justin Trudeau is calling on grocery executives to come up with a plan to stabilize food prices or face actions that could include tax measures. A Canadian Press dispatch to the Post reports that the PM said the government will be asking the five largest grocery companies including Loblaw, Metro, Empire, Walmart and Costco to create a plan by Thanksgiving. The PM said, "If their plan doesn't provide real relief for the middle class and people working hard to join it, then we will take further action and we are not ruling anything out including tax measures." The call comes as grocery prices rose 8.5 per cent in July, showing a slight easing of price growth, but still running much hotter than overall inflation. For months, food price inflation has outpaced overall inflation, which was 3.3 per cent in July. The price of groceries grew 8.5 per cent in July compared with last year, down from a 9.1 per cent year-over-year gain in June, according to Statistics Canada. The slower growth was mainly due to easing prices in the fruit and bakery products categories, the agency said. Major grocers have been accused of profiteering amid high inflation.
