Believe that after you land and complete quarantine it is up to your sponsors to start helping you get Canadian documents, find housing, look for jobs or register for school, discuss the budget you will receive based on the sponsorship amount that was required to sponsor your family, sign up for language classes if required, etc. It will essentially be up to your group of 5 to get you set up in Canada and guide you throughout the year so you will hopefully will be able to be financially independent and less reliant on others after a year.
