The consulate General of India in Toronto issued an advisory for the Indian nationals about the spoof calls claiming to be originating from the consulate regarding immigration status. 

In a statement issued Wednesday the Indian consulate said, "It has come to notice that some Indian nationals in Canada have been receiving spoofing calls about their Canadian visa/PR/immigration status, job offers, etc. from unscrupulous elements and sometime the callers have claimed to be an official from the Consulate General of India in Toronto. Please note that this Consulate does not deal with these matters."

The statement further, said, "Consulate hereby advises Indian nationals not to entertain such suspicious telephone calls made in the name of Consulate General of India, Toronto. They are also advised not to reveal any personal information or transfer any money in response to such calls. In case anyone has already received such scam calls, the matter should immediately be reported to the Canadian Anti-Fraud Centre  and the nearest police station with all details.
