Note: The table takes dual responses (for example if someone is French-Canadian they would be added to both French and Canadian). Some places of one's ethnic origin do not refer to a single specified country of origin, i.e. Spanish refers to people from Spanish speaking countries such as Colombia, Spain, Mexico, Cuba and others; or East Indian where the respondents origin could be from Pakistan, India, Nepal, Bangladesh, etc.; and the list contains about 200 nationalities known to reside in the province. However, there are options for the respondent to identify the country alone.
