Yes, a little dodgy, I know, and perhaps only a few rungs of credibility above the myriad of 'make money at home' schemes that fill pop-ups ads and clog my spam-filter on a proverbial basis.
That being said, after travelling through few a few links from a post on MyMoneyBlog, I came across InternetPaidSurveys.com, something of an aggregator for market surveyors of all colors. (There is even a list just for Canadians). From the list of companies offering surveys, I did sign-up with Ipsos I-Say, a division of the reputable and well-known Ipsos-Reid. Their focus clearly was on consumer-type research, and they offer respondents more of "opportunities to win cash" as opposed to just "cash". We'll see ...
Many of the others began asking a lot about my employer and any decision-making responsibility I enjoyed at work over various types of product or service acquisitions. Not only was I uncomfortable with this type of disclosure, but they fact they were just generating contact leads for third parties was painfully undisguised. These were an obvious pass.
If I have any success at all with Ipsos I-Say (my expectations are quite low) I will update this topic.
