CIC Tip line
To reduce the incidents of fraud, the Government of Canada has setup a tip line through the Citizenship and Immigration Canada (CIC) Call Centre. Cases that should be reported may be related to false representation, fraud or knowingly concealing material circumstances in the citizenship process. These incidents can be reported to CIC’s Call Centre at 1-888-242-2100 (in Canada only, 7:00 am to 7:00 pm Eastern Time, Monday through Friday). Those overseas can contact the nearest Canadian visa office. Tips may also be reported by e-mail at Citizenship-fraud-tips@cic.gc.ca.
