The North American Data Bank's archives on Canada largely contain PDF reports summarizing information from the Canadian Census, which (unlike the U.S. Census) includes questions on religion and ethnicity. In addition, the Data Bank has archived several surveys of major Jewish communities in Canada, which explore topics (such as travel to and attitudes towards Israel, etc.) which are not included in the Canadian Census.
Reports on Jewish Canada are organized into national statistics on Canadian Jewry as a whole (which often include geographic comparisons) and parallel reports for major centers of Jewish residence.

It concludes that the societal processes affecting Jews in both nations are similar and the gap is not as wide as some might have predicted.
