I would definitely agree. Tenured positions are the linchpin of the university system. It's only with tenured positions that you can ensure that you get the best scientists. As I mentioned, you're competing with other countries for these scientists, and I think, if tenured positions become lacking, they'll go to other places.
I know that, increasingly, many university positions within Canada rely on soft money, on bringing in the grant income, and, if you don't bring in the grant income, then your position goes away. I think following that trajectory would be a mistake.
