It's hard to know what contest judges considered, but I'd guess the hard news effort of theorion.com is what pushed it near the top of its category. I didn't see another site in any category that presented the quantity and quality of news The Orion does.
The Weal of SAIT Polytechnic in Calgary. Just guessing, of course, but I'd have to say the The Weal's photography is what helped it claim the top spot. The images on the site are just outstanding, and the editors clearly play to that strength by devoting the top of their home page to photos.
