Canada’s prime minister is taking aim at the grocery store giants, summoning the CEOs to Ottawa next week to discuss how they will stabilize food prices as they rake in record profits.

Justin Trudeau says the heads of the big grocers will have until Thanksgiving to declare how they will do this.

The PM says if they don’t, the government is willing to take action, including through unspecified tax measures that will ensure food prices stop increasing and ideally come down.

Industry Minister Francois-Philippe Champagne reinforced the demand, saying the big 5 grocery chains represent 85-percent of the market.

“There’s not necessarily one solution fits all but the demand that we’re going to put on them from the prime minister…we told them to be in Ottawa next week and we’re going to be working with them from now to Thanksgiving, we want to see meaningful action to be taken,” Champagne stated.

As the 3 day Liberal caucus retreat in London, Ontario wrapped up on Thursday, the prime minister also announced action on a plan that he first announced 8 years ago; removing the federal GST for the construction of new apartment buildings.
