I was thinking the same. I think the Liberals know that ON & BC is oversaturated with immigrants, which in turn is impacting the rents/taxes in one way or the other. Moreover, the govt has anyhow fulfilled the promise of liberal immigration policies throughout 2016/17, which saw millions of immigrants to see the day of light in Canada as their new native country. Having said that, now the story has changed altogether, given the way CRS scores are featuring since last 2 quarters, its clear that the govt has shifted its focus towards skilled immigration. Unless govt doesn’t impede the FSW’s, every tom, dick n harry is ready to land in Ontario. With FST’s and PNP’s in picture, the govt is trying to pool the people towards less populated provinces like Nova Scotia, Saskatchewan et al. So, in my point of view, in near future you will see similarities in Australian and canadian Immigration policies, and not everyone will be invited to ON & BC.
Goes without saying that I hope every deserving candidate gets their ITA, better late than never.
