Yep, Conservatives Paid for a WeChat Ad Lying about Trudeau - 2020-08-26
If a political party pays a user of an online platform to post an advertisement that lies about a politician's position on an issue, that is not a problem for the Commissioner of Canada Elections.
And as long as the commissioner decides fewer than 100,000 people saw the misinformation, the person or group behind the false ad is not legally required to be on the registry of political advertisers during an election.
How did the commissioner make sure fewer than 100,000 have seen the ad? That's not for the public to know.
