The Globe and Mail reports in its Monday edition that Nordstar Capital aims to merge with Postmedia Network Canada. The Globe's guest columnist Keldon Bester writes that with less than a year left as Commissioner of Competition, Matthew Boswell's challenge of Nordstar-Postmedia could cement his legacy as a defender of competition. Mr. Bester says Mr. Boswell has little chance of winning in what he calls this landscape of "toothless" laws. Last week, the Competition Bureau released a comprehensive study of Canada's retail grocery market, calling out consolidation as a factor in high grocery prices. Earlier this year the bureau authored a public list of more than 50 recommendations to address the problems it sees with the Competition Act. Mr. Boswell's bureau is likely bruising from its failure to block the Rogers-Shaw deal, that could see the agency liable for certain legal fees to the new entity if it loses in court. The bureau's advice in both the Air Canada-Air Transat and WestJet-Sunwing mergers went unheeded by the Minister of Transport. The challenge presented by the Nordstar-Postmedia combo is likely too good for Mr. Boswell to pass by. Mr. Boswell's assertive enforcement style has characterized his tenure.
