If both Canada and white South Africa have been divided between Anglo and non-Anglo sectors (the French-Canadians in Canada and the Afrikaners/Boers in South Africa), and the non-Anglo sectors tended to be more overtly anti-Semitic than the Anglo sectors (with some Afrikaners even sympathizing with Nazi Germany), why did Canada get fewer German Jewish refugees per capita in the 1930s than South Africa?
Canada was one of the worst countries in the world when it came to accepting refugees from Nazi Germany -- it's not that people didn't WANT to do there, it's that the Canadian government refused them entry.
Edit: Canadian only allowed in about 5,000 Jewish refugees, largely because of the influence of Frederick Blair, who was the Canadian Immigration Minister at the time. (By comparison, Columbia took in more than 7000). This was the lowest number of any allied country.
The Jewish community in South Africa is not a product of the 1930s, but largely immigrated from Europe in the late 19th and early 20th century, attracted by relative openness, a gold rush, and economic opportunities. Immigration to South Africa during WWII was extremely difficult, in part because it required refugees to traverse the North African and Mediterranean theater of war. The community did grow by about 6-7 thousands during the 1930's, but began to shrink after the war as South African Jews emigrated to Israel. Canada, on the other hand, has experienced nothing proportionally equivalent to that emigration movement.
As far as the non-Anglo/antiSemitism connection goes, it is a little bit more complicated--a dislike of immigrants in French Canada has often been linked to the French Canadian drive to protect their language and establish a relatively autonomous Francophone society. In recent years, in fact, Sephardic Jews and Muslims from former French colonies have actually found it easier to emigrate to French Canada, where they receive immigrations "points" (from a system that analyzes their eligibility) for proficiently in French.
Excellent points here. For more about 20th century Canadian antisemitism, see: None is Too Many: Canada and the Jews of Europe 1933-1948 by Irving Abella and Harold Troper. The tag line refers to the absolute desire to see not a single Jew enter Canada.
