You must be thinking of RIM in Kitchener/Waterloo. When I was at University of Toronto in the early nineties, U of Waterloo was the place to go for CS or Systems Engineering if you wanted to get hired by Microsoft.

Sooo ... it's an interesting counter-example in that it kind of supports the general argument that it's good to go where the smart and savvy people are, even if that's not just SV.
