Globe and Mail is apparently owned by a Thompson (one of Canada's wealthiest families), and the CBC is run by the government. CTV is owned by Bell Media, part of Canada's telecom oligopoly. Global news is owned by Corus, a Canadian company. National Post is owned by Postmedia which is a publicly traded Canadian company, with majority ownership from an American PE firm. Is that what you mean?
Chatham owns dozens of Canadian newspapers via Postmedia, and dozens of U.S. newspapers via McClatchy. Their operating mode is the same in both countries: fire all the writers and editors.
I thought that Blackstone owned Globe and Mail but it seems they sold it in 2021 so your info is the current info.
