(Reposting my comment here for posterity:)
First: The word is "emigration."
Second: The article itself points out why this article is bullshit:
To be sure, emigration as a percentage of Canada's overall population touched a high of 0.2% in the mid 1990s, and currently stands at about 0.09%, according to official government data.
The whole time I was reading the article, I'm thinking "Right... if you let in a record number of immigrants, then the number of emigrants is going to rise shortly thereafter. There's just more people. You need to look at percentages to draw any real conclusion."
Honestly wasn't expecting them to give the percentage like that, showing that this article is nothing but fearmongering.
