As an outsider or as a student of the college.Most universities give scholarships to their own students first.
Unless for international scholarships for studnets in a particular field who have done exemplary well in their studies.
When you apply to a college/University,there is a scholarship they will give you during your admission and many more renewable each year.I got admission scholarship of CAD 4000 in the univeristy am joining in fall 2011.
