Do I need to go through labor services to work in Canada?

Working in Canada doesn't have to go through childbirth. According to relevant information, there are no specific laws and regulations in Canada that require foreigners to work in Canada through labor service companies. However, Canada's immigration law stipulates that foreigners who want to work in Canada for a long time must first apply for a work visa, which must be provided by Canadian employers before they can apply for a work visa. Canadian employers can recruit foreigners directly or through labor service companies, so they don't have to go through labor service companies to work in Canada.
