Canada's grocery sector needs more competition to help keep food prices down, give shoppers more choice and encourage new entrants, the Competition Bureau said in a highly anticipated study released Tuesday. Most Canadians buy groceries in stores owned by a handful of grocery giants, with Canada’s three largest grocers — Loblaws, Sobeys and Metro — collectively reporting more than $100 billion in sales and $3.6 billion in profits last year, the study found.

Suncor Energy Corp. (TSX:SU). Energy. Down 19 cents, or 0.50 per cent, to $38.00. A cybersecurity expert said a systems breach at Suncor Energy Inc. will likely cost the company millions of dollars before the issue is resolved. As of Tuesday afternoon, the cyberattack was still affecting many of Suncor's Petro-Canada retail locations across the country, with many still unable to accept credit or debit payments. Jon Ferguson, general manager of cybersecurity at the Canadian Internet Registration Authority, said it's fair to assume that it will take some time before the company can get back to normal.

Thomson Reuters Corp. (TSX:TRI). Industrials. Up $4.58, or 2.57 per cent, to $182.49. Thomson Reuters Corp. has signed a deal to buy Casetext, which uses advanced artificial intelligence and machine learning to build technology for lawyers. It is paying US$650 million in cash for the California-based company. Casetext's key products include CoCounsel, an AI legal assistant that launched earlier this year that is powered by GPT-4.
