 Jewish community organizations in Canada uses a mix of the religious and ethnicity to count the Jewish population.  The religion number is used as a base and the number of people who declare a Jewish ethnicity and have no religion is added to the number (Jewish converts to other religions are not counted).  Many Jews declare a country of origin (Polish, Russian, etc.) which explains the very high number of "Polish origin" in Forest Hill etc.    02:24, 13 May 2013
