Which of the following Canadian Piers welcomed over 1 million immigrants between 1928 and 1971?

Pier 21 was an ocean liner terminal and immigration shed from 1928 to 1971 in Halifax, Nova Scotia, Canada. Over one million immigrants came to Canada through Pier 21. It is the last surviving seaport immigration facility in Canada, which now houses the Canadian Museum of Immigration, the Nova Scotia College of Art and Design as well as various retail tenants.

The war almost completely halted Canadian immigration, but Pier 21 quickly became a major embarkation port for troop ships. Canadians and other Allied forces boarded hundreds of converted ocean liners ranging from the giants like the RMS Queen Mary and RMS Queen Elizabeth to smaller liners such as the RMS Ascania. As the war continued, a special medical embarkation unit was established at Pier 21 to move wounded soldiers from hospital ships to special hospital trains as the hospital ships brought wounded Canadians home. Most of the over 90,000 aviators who came to Canada as part of the British Commonwealth Air Training Plan landed at Pier 21. Over 2,000 child evacuees from the United Kingdom arrived at Pier 21 during the war, fleeing the Blitz.

After the war, war brides, and several major waves of immigrants arrived at Pier 21 beginning with the Displaced Person refugees from across Europe, including many Holocaust survivors. These refugees were followed by large numbers of post war economic immigrants from several European countries such as Britain, Italy, Germany and the Netherlands.
