Who called from 4163848000

This number called 4 times in a matter of 20 minutes.

I had the same thing - during the gold medal hockey game of all times!  Annoying.

YOU PROBABLY WON A PRIZE/CONTEST THIS IS # THEY CALL U FROM !!!

Wrong.  They probably won a chance to be scammed.  They should not call back.

And found out it's the MAIN SWITCHBOARD number to CTV located @ 299 Queen St. W. However, unless you know precisely who called you from this address, they WILL NOT be able to tell you who was trying to get in touch with you or why. Hope this helps everyone :)
