Canada Sues Google Over Online Advertising, Seeks Ad Tech Breakup

The Competition Bureau said that such action is necessary because an investigation into Google found that the company "unlawfully" tied together its ad tech tools to maintain its dominant market position.
The matter is now headed for the Competition Tribunal, a quasi-judicial body that hears cases brought forward by the competition commissioner about non-compliance with the Competition Act.
The bureau is asking the tribunal to order Google to sell its publisher ad server, DoubleClick for Publishers, and its ad exchange, AdX. It estimates Google holds a market share of 90% in publisher ad servers, 70% in advertiser networks, 60% in demand-side platforms and 50% in ad exchanges.
