You right, its not a big city so it may not be the most lucrative. I think it could be worth a tour once a year planned way in advance, especially during the "low season" because the local market is pretty bad... Maybe some guys have their "hidden gems" or something but there is no agencies that i know of (used to be the old news paper ads back then but thats pretty much gone) and everytime i check classified ads for Sherbrooke, all i see is scams/shady ads or nothing pick my eyes.
I guess it would need to be a "tour on prebooking only" kinda thing, to be sure its worth it. Last year i saw Melodie Laurent (she is from Quebec) in June. Had a great time. I notice ocasionally some providers come but its rare. That said, in my case, since i only book 6-7 times a year, there is also chances the timing do not fit if its only announced a few weeks in advance. But ill throw this out, during winter (November to March), i have very few desire to go to Montreal (unless there is a show or something) so that would be a great time for me to see someone in Sherbrooke
