Some Countries See Migrants as an Economic Boon, Not a Burden

The article also doesn't define the relation between migrant and refugee. If you're cherrypicking migrants, which I believe Canada is doing, you'll have a easier job at integration.
According to http://www.cbc.ca/news/canada/syrian-refugees-canada-united-... Canada pledged to "welcome" 25,000 by next year. That's almost as many as crossed the borders to Europe only within a few days.
As the title says "Canada focuses on assimilating educated foreigners who fill job needs, in sharp contrast to Europe", so basically cherry picking like hbogert said. In this case it is easy to assimilate and integrate. Try the same with hordes of "less educated foreigners".
If we draw comparisons then please not apples to oranges.
Some will not integrate and has other purposes than to flee either war or poverty. Some do it unconsciously. Either way I wouldn't say immigration from certain cultures has served Scandinavia well. I'm from one of them that's been a huge burden. The future looks bleak, for everyone involved. Worse for those stranded between Islamists and Assad l obviously.
However, it confuses the issue to bring in the recent refugee crisis in Europe. As several other commenters have pointed out, accepting 25,000 hand picked Syrian refugees, while laudable, is on a completely different scale than 1,000,000 refugees of random backgrounds flooding across the border.
I think it's green...

Increasing the supply of labor while not increasing the supply of capital can drive down productivity and wages in the nation getting migrants. If they come with accompanying capital, it could help maintain or improve productivity.
That's only true if you limit your definition of "cheap" to mean "cheaper than historical norms in geographies that have historically had high labor prices relative to those prevailing in migrants' original locations".
There's a common myth that immigration somehow reduces the cost of labor. This is nonsense. It reduces the price of labor in the location receiving the migrants (by increasing its supply) while simultaneously raising the price of labor in the migrants' original location by reducing such supply (both by direct labor outflows and by the increased leverage held by those who don't migrate, since they can now credibly threaten to do so).
Pretending that free migration is bad for workers is incredibly parochial and ignores the vast, vast majority of the world's workers, who currently live in places like India and southeastern Asia, and who would strongly benefit from the upward wage pressure that freer migration would bring about.
