Its not about hitting Montreal agencies. This is a big deal even in Canada because the website was an international advertizing platform. Many Canadian women and agencies (at least Toronto agencies) used it for advertising. Whats more, to make sure they were not being used for underage or trafficked women, Eros insisted that women provide government issue ID verifying their age and identity in addition to unblurred pics. They wanted to be absolutely certain they were not part of any of that and thought it was enough to be ignored by the authorities. So now you have at least 40-50 women in Montreal and about 80 in Toronto (not to mention Vancouver) whom Homeland has real information on.
The possibilities of what could happen with that info is endless: Barred from entry into the US - which could affect 'touring' in the short term and maybe legitimate job and business opportunities in the long term. Sharing info with Revenue Canada: A number of these women could be subject to tax audits and get in trouble if they did not report their income. Not to mention what could happen if this data cache is 'leaked' and falls into malicious hands. A jealous x-BF finding out what his old flame is up to and following her to a meet with a John?
