To clear this up: 

Poilievre's call to "stop the deportations" is rooted in his brutal criticism of the Liberal government's handling of immigration, particularly the influx of international students and temporary foreign workers.

He said this because of unfair deportations of students whose paperwork was not properly vetted by authorities and the applications were faked - they lost all they savings to start a new life in Canada.

 Poilievre wanted to give those who were cheated a shot at citizenship. NOTE: There were no guarantees they would have gotten it, but his request was in fairness to them being screwed over.

You guys are liars and spin things, and that's why the PPC is terrible.
