Getting US websites from Canada

When I am traveling in Canada several months per year, I can’t get access to certain functions at some US websites. For example, I can’t run streaming US television programs at HULU. It says this is not available in Canada. My US internet connection is Comcast but when in Canada, I am accessing the internet through Nova Scotia C@P, the government community access internet wifi system. How can I set my internet access to show I am accessing the internet in the US so that I can get access to these functions?
