Frederick Charles Blair, ISO was the director of the Government of Canada's Immigration Branch of the Department of Mines and Resources from 1936 to 1943. Blair developed and rigorously enforced strict immigration policies based on race and is most remembered for his successful effort to keep Jewish refugees from Nazi Germany out of Canada during the 1930s and the war years that followed. Between 1933 and 1939, Blair's office allowed fewer than 5,000 Jews into Canada, in comparison to over 200,000 allowed into the United States, and 20,000 into Mexico. After the war, between 1945 and 1948, the Immigration Branch accepted only 8,000 Jewish Holocaust survivors. "That record is arguably the worst of all possible refugee-receiving states", wrote Abella and Troper. Blair's rigorous enforcement of anti-Semitic immigration policies sealed the fate of thousands of European Jews who would have escaped death had Canada not turned them away.
