LeBlanc told a virtual conference on democracy today if there were a simple answer, many other western democracies would have already passed such laws.
He says the internet and social-media platforms must be a home for free speech, a critical element of any democracy.
However, LeBlanc adds, they should not be forums for hate speech, racism and disinformation.

LeBlanc prefers educating online users, requiring social media companies to be more transparent, and naming and shaming them when they fail to live up to commitments.
