I hesitate to jump in on this discussion, but ...
I've been perusing the internet as a result of this discussion. Suzanne Jenkins was a doctoral student at Keele University in England whose thesis revolved around sex work (escorting, not stripping, mind you.) She surveyed 483 sex workers, and found that 93% liked escorting for money, and 86% felt they were never or only rarely exploited. 25%, however, felt that THEY had exploited men, usually because they felt that at least some of the men who hired them couldn't really afford it. Slightly over 50% said that they enjoyed the sex, and over 70% said that their self esteem had improved as a result of sex work.
Jenkins' thesis was written in 2009, and it was entitled "Beyond Gender: An Examination Of Exploitation In Sex Work." I can't find the actual thesis, but I've seen it footnoted, with those statistics cited. I've also seen her conclusion quoted, which is that criminalization of sex work is unhelpful. It is an English study, but I see no reason that the situation in Canada would be markedly different. An academic study does seem more reputable than "several" experiences. PhD students are held to fairly rigourous standards in research and survey work.
