Hello Canada,
As a Meta (Facebook) employee. - Over the next 2 days, you're going to see 1 of 3 things.
1) A sudden spike of pro-conservative post. The aim is to make the conservatives seem popular. Much will not be from actual Canadians.
2) Conservative Ads.
2) Your mainstream media is going to focus on the conservatives, as if they are the primary party in your country. Even if the news about them is bad, the aim is to bring them front and center.
