You will never get a definitive answer about this. The CBC article is a damage control piece. Nothing more nothing less. Think for a second if you can. Ordinary folks in Montreal, Toronto etc... are getting bombarded with "scam Phone call in MANDARIN" This make no fucking sens. in the Province of Quebec Mandarin is spoken by less than 1% of the population. Why the hell would you want to pay to annoy 99% to gain the attention of less than 1% of the population?!? There is more to this. And if you are not blind to what the Hell is going on in the world this theory is looking more and more plausible.
