Immigration to Canada for the express purpose of creating a start-up can be a bit difficult for a young 'un, at least. You need to have a net worth of at least $CAN 300K and previous experience managing a business in order to qualify for Entrepreneur Class immigration status. (Self-employment Class status is only available to people in a clearly-defined, limited number of fields -- mostly cultural and athletic.) If you can meet the requirements, though, there are some areas that are particularly kind to high-tech start-ups. The Kitchener-Waterloo area has become the Canadian take on Silicon Valley thanks in large part to the University of Waterloo (still one of the best math and CS schools in the world, with co-op students more than willing to do internships) and the influence of companies like Research In Motion. Ottawa is still trying to attract tech, even if Corel's glory days are past. Vancouver is a sort of northern outpost of the Seattle area (rainy, no real winter, but it's God-awful expensive to live there). Calgary is another hot spot, but you need to be of a certain temperament to "get" the place. And there's always the Toronto area -- great for amenities, culture and so forth and the de facto capitol of all things business, and there is no lack of code monkeys if you feel you need them. There be hackers of both hardware and software in the Greater Toronto Area, but not so much within the city itself.
