Canada has 34,880,000 people in it, so a CAD 20,000 basic income would cost CAD 697,600,000,000.
According to http://www.fin.gc.ca/afr-rfa/2013/report-rapport-eng.asp#a3, Canada's total government revenue (at the federal level) was CAD 256,600,000,000.
So Canada would have to raise taxes by 170% to provide this basic income, and raise them again if they want to provide any of the services they do today. (National Defense, Healthcare, etc.)
