They called me & asked for me by name, then hung up when I told them that they had reached me.

Called once last week and twice this week - didn't leave a voicemail

They have called the past 8 business days, once per day. Apparently this is the green party. I have previously asked GPC to stop calling me and they still call.

The phone number (647) 725-2170 originates from a robot dialer operated by Globility Communications Corporation.  Globility Communications has an F rating from the Better Business Bureau.  (647) 725-2170 is not the full phone number.  This robot dialer is using a couple of international phone numbers 011 64 7 725 2170  and 011 1 (647) 725-2170 to cover its identity.  It is unlikely that the calls are originating from a political party who trying to gain your support.

It's the Green Party of Ontario, not Canada.

If you don't want someone calling you, all if you have to do is pick up and say that.
