The watchdog has reason to believe the tech firm’s move to prevent third-party buying tools from accessing and selling inventory on the video platform starting in 2016 and other practices “substantially prevent or lessen competition” in the advertising market, it said in an affidavit to the Federal Court. The filing was first reported by Blacklock’s Reporter. Google spokesperson Molly Morgan said the firm will “continue to engage constructively” with the agency “to answer their questions and demonstrate the benefits of our products to Canadian businesses and consumers.” (The Logic)

Talking point: The bureau has gone to court seeking documents and information from Google to conduct its probe. The agency is once again following international peers into the tech antitrust arena. In June, the EU launched an investigation of Google’s requirement that advertisers buy YouTube spots via its own services as well as other ways it’s involved in the ad tech stack. Back in Canada, Google is asking the court to seal the bureau’s filing, citing “serious issues of confidentiality” and “commercially sensitive information.” The company declined to comment on the sealing request. The first hearing is scheduled for Wednesday.
