This person said they were from Service Canada, and gave the name Tim Liu and the number (416) 952-7970.. I asked for a 1800 number and he said there was not one, and this number went sdirect to his desk I called Service Canada, and had them check.. This name or number does not come up in any other thier databases as being associated with service Canada. I don't know what kind of a scam this, but it sure looks like a scam to me
