As soon as you leave the ceremonial areas of Ottawa (think: Parliament Hill, the Supreme Court etc.) and get away from the other obvious touristy areas (ByWard Market, The Canadian Museum of *.*, etc.) it's VERY easy to forget you're in the national capital of a G7 country.
Ottawa is easily one of the most modest capital cities you'll ever come across, and it's one that's very much in touch with nature and outdoor living. We are the second-coldest capital city in the world, which means when summer comes, we enjoy it. We do everything we can to extract the most out of summer, and depending where you look, it can be easy to forget you're smack in the center of a city!
