Josh Lyman, a character from the hit show West Wing, said, "There are only two things that ever stopped the government from doing anything money or politics." If this is the case then presumably, money or politics will also cause the government to take action and international students traveling to Canada certainly provides money according to a report released by the federal government this past fall.
Foreign Affairs & International Trade released an article in late October called Impact of International Education in Canada which outlined that the "total expenditures by international students while they study here (tuition, accommodation, living costs, travel and discretionary products and services) resulted in a $6.5 billion infusion to the Canadian economy in 2008."
The trend toward globalization would imply that this figure will grow in years to come and its hardly a secret that many schools rely on financial contributions from students abroad to help their bottom line. However, let's not forget that international students bring a wealth of experience and knowledge to our schools which provides a "priceless" aspect to learning for all students (staff & faculty).
