That's that amount of money Canada's seven million foreign born residents removed from the Canadian economy in 2012 as remittances according to a World Bank study.
I don't have a problem with remittances. I would probably do the same thing. It beats foreign aid as it goes directly to the people who need it instead of corrupt government coffers.
But, on a balance sheet this is a loss for Canada. It's been established that immigrants' contribution to the economy is negligible. They are also a tax burden according to a much cited, and relatively unchallenged, Fraser Institute study. With TFWs compounding the costs to Canadians by contributing to regional unemployment and wage suppression now we learn Canada's foreign born, both permanent and temporary, are removing some $20 billion dollars from the economy yearly.
Since none of this is beneficial to the average Canadian the immigration system is turning out to be a money hemorrhaging investment only the shadiest of financial advisers would recommend.
