I wrote a feature that appeared earlier this week in the National Post looking at how some of Canada's high-tech communities - Waterloo and Ottawa - have come back to life in the past couple of years. In Waterloo, the revival can be seen in a new industrial park where three new buildings have sprouted up on land where farmers grew corn a couple years ago. While Waterloo isn't a new story, it's interesting to see how people are excited again as Google moves into town and RIM continues to expand its footprint in the city.
