Since there's no gate at the National War Memorial and the Tomb of the Unknown Soldier we're making estimates based on people visiting Parliament. Approximately one million people a year visit Parliament, and since Canadians pay so much respect to their veterans we assume that you don't come to Ottawa to visit Parliament without paying respect to the veterans who have put forward their lives for this country. We are also assuming people visit the memorial site. That's how we estimated that there were about one million visitors per year.
