Over the weekend, a series of media reports revealed that a data analytics firm hired by the Trump campaign to target voters, called Cambridge Analytica, obtained information on 50 million people from a researcher who scraped it from Facebook. It wasn’t a breach, but it was a startling reminder of how Facebook as a platform can be made to work against users’ interests without their knowledge.

This has put Facebook in a precarious position in Canada, where the social network has been doing damage control since the 2016 US election revealed the extent to which information on the platform can be manipulated or designed by foreign political actors, and gamed in general. In October of last year, Facebook launched what it called the Canadian Election Integrity Initiative to allay fears that the next Canadian federal election—slated for 2019—will be troubled by similar shenanigans.
