I agree that hi-tech and financial sector is more dominant in high-paying job markets. But some of us want to live here because we love other aspects of Canada as well, not just the career. No matter what industry you work in, you will need all other services and products to live to you fullest extend in Canada, and that's also the market and the source of employment.
I agree with you, there are tons of other industries supporting the banking and IT sector. While it may not be as lucrative as the banking and IT sector, they all play an important role in the macro economic sense of things.
