Zuckerberg's appearances on Capitol Hill come as Facebook has revealed that political consulting firm Cambridge Analytica obtained data on up to 87 million users compared to the previously reported 50 million users.
"These investigations will examine whether the organizations are in compliance with Canada's Personal Information Protection and Electronic Documents Act.and B.C.'s Personal Information Protection Act", a statement from B.C.'s Office of the Information and Privacy Commissioner said.

The spokesperson said protecting data was "at the heart of everything we do" and require the same from people who operate apps on Facebook.

In the Q&A, Zuckerberg said Facebook will consider taking legal action against Cambridge Analytica.
But, also pushing back on criticism Facebook takes information without consent, saying, "The vast majority of the data that Facebook has about you is because you chose to share it".
