Facebook users will find out if their data was used by Cambridge Analytica

Facebook users in Canada and the US will find out if they had their data used by Cambridge Analytica, the company at the centre of a data mining controversy.

Facebook founder Mark Zuckerberg says all users will receive a notice Monday on their feeds with a link to see what apps they use and what information they have shared with those apps.

Users will also be told if Cambridge accessed their data.

Yesterday, Zuckerberg apologized again for his company's handling of user data.

The social network now says 87 million of its users worldwide, including 620,000 Canadians, had their information improperly shared with outside data miners through app they use or their friends.
