Scam. Just block this number. They've called me multiple times, I initially picked up because it has a Toronto area code, and asked them to remove me from their list. The guy got upset and hung up on me. I have now asked them three times to remove me from their call list. You can be certain they are not a legitimate or professional company, as they are breaking telecom related laws in Canada by calling me back after I have asked them to remove me from their call list.
