At census time, most respondents report only one mother tongue or home language, providing thus a single response. However, some of them provide a multiple response. That is, they report more than one mother tongue or home language.
To simplify the analysis, in most of the statistics used in this report, the multiple responses were equally distributed among the languages reported. For example, if a given number of respondents provided English and French as their mother tongue or home language, half were assigned to the 'English' category and half to the 'French' category. The same procedure was followed for multiple responses which included an official language and a non-official language.
When the analysis was done for one specific language group, all responses (single and multiple) corresponding to that language were taken into account to establish its relative share based on the 2006 Census data. For example, to establish the proportion of people with 'Spanish' as mother tongue in the total population of a census metropolitan area, all responses including 'Spanish', were taken into account if they were reported alone or with English or French.
In the case of language transfer, which refers to a language other than the mother tongue being the one that is used most often at home, only single responses were taken into account.
