The Canadian Museum of Immigration History at Pier 21 is a national museum. It is also a National Historic Site of Canada. It has played an important role in Canada's immigration history, carrying the memories of 1 million immigrants who came to Canada. Arguably, one in five Canadians today can trace their origins back to Pier 21. The glorious history attracts a large number of tourists and new immigrants to visit. Although it is a national museum, it focuses on the experience of tourists and is committed to allowing tourists to participate in history. It is a rare interactive museum.
