No.
I think there are a variety of measures. Generally, the universities in the top twenty in the world have some very clear attributes, and that is that they are destinations for everybody. Faculty want to go there, the best students want to go there, and the best researchers from around the world want to go there. I think if you're near the top twenty, you know, because people are beating a path to your door. For me, that would be the metric, and I don't think any Canadian university has that kind of attraction.
