Best/worst high schools?

What are the best/worst high schools in Calgary? I grew up in another city but had lived in Calgary for years. Now that my kids are of school age I am looking to choose a new community based on what school they will end up in.

My wife went to high school in Calgary, but where she went is not an option (affordability).

The school we are most interested in is Western Canada, so any information you might have on that would be good.
