If you are applying for a start-up Visa Program along with a team of business people for one whole business, IRCC allows a maximum of 5 entrepreneurs to join you, among the five IRCC will categorize the members as essential and non-essential to the proposed business. Here, essential person means the one who will support and invest the said business and if IRCC refuses the essential applicant’s profile, the other four applications will also be impliedly refused.
