(Bloomberg) -- Canadian lawmakers have summoned Facebook Inc.’s Mark Zuckerberg and Sheryl Sandberg to testify at a parliamentary committee after a watchdog report found the social media giant violated Canadian privacy law.

Canada’s Standing Committee on Access to Information, Privacy and Ethics issued the summons Tuesday in a closed-door meeting, according to minutes published afterwards. Zuckerberg and Sandberg were summoned to appear at a date that hasn’t been determined.

Canada privacy watchdog, Daniel Therrien, last month said Facebook committed “serious contraventions” of Canadian law in the Cambridge Analytica saga, but that Facebook essentially dismissed the findings. Therrien said he had no legal authority to enforce it, leading to the committee’s vote on Tuesday.

“This is a highly unusual step to take but Facebook’s disregard for the rights of Canadian citizens and the recent finding of the Privacy Commissioner that Facebook broke Canadian law has necessitated our decision,” lawmaker Charlie Angus, who put forward the motion to summon the executives, said in an email Wednesday. “We will see if they are willing to respect the Parliament of Canada and the presence of legislators from around the world.”

A Facebook spokeswoman did not immediately respond to a request for comment.
