What matters (for those categories) is your nationality and where you will be attending university, not where you happen to be attending high school (A few of the awards for Canadians might also require you to be attending a Canadian high school).
So if you are Canadian and plan on going to a US school, the first category does not apply.
Remember that it often takes just as long to do a search or two on Google to try and find the answer to your question as it takes to type it in a post here, let alone the time waiting for a reply.
If your question is "What mark does it take to get into University X", or "What are the requirements to get into University X", it's on their website and/or
electronicinfo.ca (for Ontario schools). Particularly for Ontario schools, those ranges are a pretty good picture of what kind of mark will get you into the program, and if you're more than a couple percent higher it's practically guaranteed unless it requires a supplementary form.
