The Area code 647 is the Overlay Area Code for the Toronto Region, in North America. So, calls that begin with 647 are originating at a switch that has support for that area code. This means an OUTBOUND agency can rent a block of phone numbers, and use it for a Specific Campaign or a pool of Outbound IDs.

Currently, as of 2014-01-17 , In Ontario, there are TWO By-Elections on the go, and this particular number is being used from a Donation Campaign Office of the Ontario PC Party. It is a 3rd party office ,that is soliciting for contributions to help defray the advertising costs associated with the current campaign, and if there is a surplus, to go towards General Expenses of the PC Party of Ontario. (doubtful there would be a surplus, but you never know).  IF you do not wish to be contacted by this office, Call the PC Party of Ontario, and ask to be placed on their Do-Not-Call-Me-Ever-Again-This-Is-So-Annoying list.

From their current website: "We can be reached by phone at (416) 861-0020,
or toll-free at 1-800-903-6453. Fax us at (416) 861-9593."

Didn't answer. Googled number after and then hit return call and listened for identity.
