International students represent an economic bonanza worth tens of billions of dollars to countries like the United States, Britain and Australia.
 
They were the first countries to really take advantage of this market. Canada, although late to the party, has made up significant ground in a short period of time.
 
The bottom line for Canada is the competition for international students is about to get fierce. Estimates of how much money international students mean to the domestic economy range from $6-billion to $10-billion.
