My plea....I am trying to find out how to get a list of businesses in Ontario Canada that have open labour market numbers for hiring. My daughter and son in law are trying to find jobs here in Canada to be able to stay. When they get interviews, the companies won't hire because of having to call hrsdc to get a labour market number. Does anyone out there know anyone that can help????????? We are running out of time!!!
