6. May a candidate be refused under the Skilled Worker category even if he or she scores more than 67 points and has the appropriate work experience?

Yes. Canada accepts Skilled Workers based upon their ability to become economically established in Canada. If the Canadian Immigration Visa Officer concludes that you will not become economically established in Canada, the Visa Officer may use his or her negative discretion (referred to as substituted evaluation) and refuse an application even though the applicant scored 67 or more points. Moreover, an applicant may be inadmissible to Canada due to health or security issues, no matter how many points are rewarded under the Skilled Worker Category.
