The number that called was 011 778 678 6449. It suggested some winning from Air Canada. I simply hung up. Phone call came through at 5:07pm on Wednesday, October 28, 2015. The voice was a robotic female voice. Upon trying to locate where the call was coming from using the 011 prefix, I have not been able to trace this call, however, this 800notes site is what came up when I did not use the prefix 011. I do not know if it is a scam but most likely it is.
