No one can tell.
Definitively not this summer, and it will not be 100%(it's impossible, it will never pass the current way they present the bill)
As for stopping advertising...I don't think I will stop advertising myself.
As of now, it is uncertain of how and what they mean by not "advertising sexual services" but you can advertise your own self?
I'd say at least keep the websites and advertising on boards that are not base in Canada up ( I doubt the legislations will apply when out of the country...so that's a loophole)
