I too live in Ontario and receive calls with no message etc....

another fellow canadian here being harrassed by this number. they never leave a msg, and i dont bother answering

also a resident of canada, ontario. i get calls at my office from this number several times a day. it never leaves messages or says anything on the rare occasions i pick up. i also get several calls a day from other american phone numbers, sometimes offering me a vacation deal or what have you, but mostly just leaving dead air. some other numbers include:
1-616-980-2982
1-701-456-3703
1-317-634-8133

BE WARNED!

I have gotten calls from this number everyday for the last week, all dead air each time. I have reported it to the authorities, it constitutes as harassment.

Several calls, no messages.  I stayed on the line for the first few seconds once, and after repeated "hello", "hello" etc. was greeted by a telemarketer selling PRIMUS home phone packages.  While the caller gave me a very anglicized name, I believe that by his South Asian accent and the length of connection time (dead air) that these calls may be originating from an overseas call centre.
