Hi, richmond anon.  Re: "high immigration quotas": definite "high" and provide rationale.  Even your misleading figure of 600,000 is less than 1% of our population.  Between 2010 and 2014, annual average additional full time residents--ALL classifications--  just 261,000.* 

In 2014, for example, Canada welcomed a paltry 361,000 Chinese visitors--all categories--and THAT figure was a record.*

Misleading: you've lumped all categories to make up your "high immigration quotas."  Many don't qualify as "immigrants,"; no permanent full-time residency. TFWs aren't full time residents.  Canada calls those who hold 10 year visas "temporary" -- and they are. Visas work both ways--Cdn. businessmen use then, too.

Elsewhere: last year, Australia started its 10 year visa pgm.  Why?  The PM said a million Chinese visitors to Australia drop over 8 billion there annually. He wants more--like us.  China is Canada's #2 trade partner--given U.S. changes (NAFTA) a bigger Asian focus is OK.
