It's a shame that more Waterloo folks don't stay in Canada and build their businesses here. Unlike when I was at UW, nowadays there is plenty of investment money available in Canada and significant tech hubs in Vancouver, Toronto and Waterloo itself. Not to mention the fact that even in less major Canadian cities (or the US Midwest) there actually is a tech scene happening and people are starting new businesses. It is no longer necessary to move far from home to build a tech business.
