7.15.            At the time of writing of the present Guide, Canada did not collect mode 4 data. However, some of the questions on its census questionnaire could be useful for the collection of such data. For example, the Canadian census questionnaire[1] identifies whether the person is  self-employed or an employee, as well as his/her occupation, the industry of the firm and whether the person was generally working in or outside Canada during the previous week.  Countries with a portion of their population travelling abroad for work purposes may be interested in knowing more about the purpose of such travel to determine whether it is relevant to mode 4. If information is collected on the duration of residence, information could also be gathered to learn if the employer is a multinational entity, or whether the person is in the country for purposes relevant to mode 4 (i.e. whether the employer is based in country of origin).
