I did a little search and came up with this:

Deluxe Windows Industries
Address:    2 Shale Gate North York, Ontario M3J 2Y8
Phone:     (416) 740-4368
Fax:     (416) 740-5728

This seems to be the company: http://www.deluxewindows.ca/contactUs.php
http://canada411.yellowpages.ca/bus/Ontario/N ... es/3613664.html

The callers claim to work directly for Deluxe Windows & Doors, and not for some marketing company.  When I called their office, the person who answered claimed the same thing.  They maintain an internal do-not-call list, to which I asked to be added.  We'll see if it helps.
