There are, demographically, two facts which in themselves place Canadian Jewry at significant variance with Jews in America. In the first place, by and large, Canadian Jewry is a full generation younger than American Jewry. Canada experienced a proportionally large influx of Jews following the Second World War; the children of these immigrants now represent a second generation in Canada who are a full generation 'closer to the boat' than America's grandchildren and great-grandchildren of immigrant Jews. The character of Canadian Jewry is influenced by these post-Holocaust refugees, to an extent not felt by the American Jewish community.
The second fact, no doubt related to the first, is more surprising. Per capita, Canadian aliyah approaches twice that of American aliyah. To the best of my knowledge, this startling statistic has never been recognized in any written source nor explored in depth. For studies of western aliyah, Canadian immigration to Israel is a telling indicator of Jewish behavioral priority that must be scrutinized closely to understand more fully the forces behind the 'pushes' and the 'pulls' that result in immigration to Israel.
