This number is listed as a teleReasercher.  If they are a ligitimate RESEARCH COMPANY then they can legally call until 10pm respondent time.  However there is a new list being created at the end of this month on the CRTC site to have your phone # blocked from TELEMARKETERS.  There is a difference.  But you should all go to the CRTC site to read the rules and regulations for having your number removed from these companies.

This number phone i answered it as it was after 9pm no one on the other line.

they can call because fall under the research catagory that
and thus are not considered telemarketers

I think all this flow of numbers, can only come from the phone company itself, as you see them changing phone numbers, and there are a great many phone numbers of them. Who can afford himself to have so many phone numbers, if it is not from a phone company itself, or from a few of their employees.

Have a look at the List of reported phone numbers:

We have been receiving calls from this number several times EVERY DAY. Thank you for this site. I called the number +1 866-652-5160 listed above and requested a supervisor, and asked to not be called anymore. He took my phone number and was polite about it. We'll see if they keep calling.
