Question for Canadians really: I'm visiting some friends in Canada this summer and I was wondering if, while I'm here, there were any good mathematics institutions to visit. I'm visiting friends in Ontario, but I have a lot of time off and was looking to travel and curious to met some mathematical colleges in Canada. Its a weird question, I know, but I'm a math grad student at a fairly small department here in the states and I like meeting people all over the world. My supervisor doesn't have any ties to Canadians and outside of UofT I don't know of anywhere that has any sort of reputation. My work is in algebraic topology with ties to mathematical physics and I just haven't heard of any Canadians working in similar fields. Anyone know any?
