The LFS Additional Content Component has been developed to enable the LFS to on occasion, include a short series of questions of a particular interest, as requested by external clients. The LFS will not have this component every month, only from time to time, as required. Four questions were added to the Labour Force Survey for the March 2012 collection. These questions are being added at the request of Human Resources and Skills Development Canada (HRSDC) to collect information related to Canada's official languages and the linguistic characteristics of immigrants in the workplace.
