Just for the record I live in Montreal,Quebec and most 514 numbers belong to residents and legit businesses. 514 and 450 and the 2 main area codes in Montreal. So not answering it because it may be from a telemarketing company or some other ridiculous company is not the best idea. I would suggest that you google search the number to see if the number that called is from a residence. It could be a friend or relative that is visiting in Montreal, and wants to talk with you. Just saying cause you never know, as I said 514 is one of the main area codes here. I know it sucks we get telemarketing calls here too from other places. Have a good one, keep smilin :)
This number looks to be an "autoprober". They call to see if a live person answers, keep results to build database of "targets". Recommend that you do not answer, or more marketing calls will come. Call orginates in Montreal, Quebec, a North American major centre for phone-crimes, "boiler-room" scams, fake stock schemes, lottery-scams, and mail fraud. If you call this number, you get a message in French, telling you that "This Number is Invalid.". You have a very high likelyhood that any product or service offered by anyone from this number is bogus, as no legal business would seek to screen itself from honest inquiry or callback.
Hence, I suspect 514-329-9199 is probably being used by Quebec-based organized crime.
