Banting is a totally new program. It's a prestigious program to attract the best and the brightest to Canada to do post-doctoral studies. It's a program that's open both to Canadians and to foreigners.
The Vanier program is much the same. It was started a few years back and it's to attract students at the level of graduate studies, PhD students.
The Canada graduate scholarships program went through a temporary increase in the amounts invested in it. It's also a doctoral program for Canadians doing graduate studies in Canada.
