@xtaldave Immigration, if well done, can be very good for economy.
But you have to do it well and administer it in order to prevent clashes.
You have to provide houses and jobs for those immigrants in order to avoid poverty which would destabilize the system.
I'm not really sure how they're going to do this, they're going to increase their population by 4% in 3 years, that's a lot of buildings to add.

I think what Canada wishes to do is a good idea for Canada and that it may turn out very well, the main concern in the article is the disappearance of French, which doesn't seem like a huge issue or something that can't be solved.

However, it's very unfair to compare immigration policies of other countries with this one from Canada.
What Canada is doing will probably work but may not be applicable to other countries.
First of all, Canada doesn't have immigrant streams and thus they could close immigration whenever they wish to.
Canada is picking the best educated and most valuable immigrants, they even wish to reduce family reunification.
A lot of other countries simply can not do these things.

Overall, I believe that this is a good decision and that other countries could learn some things from this example; but definitely Canada is in an advantageous position to enact these policies.
