They've been calling me too....looked it up....this is what I found....

Probably looking for donations, if you have donated before....

Hope this helps... :)

Canadian Diabetes Association
45 Montreal Rd, Vanier K1L 6E8, Ontario
p: (613) 746-4633

This IS the Canadian Diabetes Foundation. I gave them my number (& allowed them to call me) because I am a regular contributor  to the CDF. You may request that your number be removed from their database, but that might not be sufficient.I do not know about the DNC (Do Not Call) rules precisely, but many (meaning LOTS) of DNC requests have resulted in my getting calls from other telemarketing a-holes. In this case....... caveat emptor .... Let the buyer beware...There are too many ways for a biz to circumvent federal rules such as Do Not Call. Since I use a cell phone as my primary phone connection, I have ID'd this number as "CDA Spam". Thus, if called, I do not answer. (or do, if I have a donation on hand) Easy. For me, at least... (btw, I am a Fido customer)

Keep getting calls from (613) 746-4633 almost daily. Name unknown but someone definitely hangs up after listening to me say "hello" several times.

This person calls often and does not say anything or leave a message.This is quite annoying and would like it to stop.

Got a call from (613) 746-4633, which is a Bell managed residential or business land line in Ottawa, ON, from my search.

Sure, they need to fix the problem of over dialing.  Poor people can have less clothing because of it.  Is that a reasonable consequence?  Perhaps alittle unfair.  Since the 70s, minimum wage has decreased quality of living in conjunction with corporate market fixed prices, making life tougher for more people.  The calls are annoying, but I will still give.
