Statistics Canada (statcan.gc.ca)
Statistics Canada, our nation's official statistical agency, collects
some information regarding participation in and beliefs about
religion, though it is less detailed than in many countries. A
guide to religious data from Stats Can sources is available at:
statcan.gc.ca/search-recherche/bb/info/3000017-eng.htm. It offers summary and highlight tables for religion data in all provinces and territories based on 2001 Canadian census data (updated every 10 years). There are tables which break religious affiliation down by age, language, labour status, and industry. Data from the Marriage Database (terminated in 2003 due to changing definitions of marriage in various jurisdictions) are available for 2000 to 2003. These data record same- and mixed- religion marriages according to variables selected by the user. (For example, from 2000 to 2003, the number of marriages between a Jewish groom and an Orthodox bride were 21 in 2000, 21 in 2001, 24 in 2002, and two in 2003.) There are also a number of published reports available here dating back to 1999 and as recently as 2008 on various topics, including "Who's Religious?," "Hate Crime in Canada," and "Are Children Going to Religious Services?" as examples.
