Applying without spouse

Please I need advise… I am in my early 40’s and interested in Canadian immigration program, I have read and understood that PNP would best suit me but what are my chances? I have 2 kids but my husband is not interested in migrating, I am an MSC graduate of environmental resources management with over 4 years work experience in my present job, I would like to know what my chances are if I am to apply alone with my kids.
