Me moving won't:
A) make the law unenforceable
B) cause me to stop correcting you
It is reasonable to speculate how much energy the police will put into enforcing the law, and the answer will be different between Toronto, Montreal, Vancouver, and Calgary. This is true in the US as well, the level of enforcement in San Francisco is pretty different from enforcement in Florida. Though it is a difference of degrees, both jurisdictions run periodic operations against prostitution, but differ in frequency and scale.
It is dangerously misleading to think there is some get out of jail free card, some magical words to say, some clever trick you can use, to evade prosecution in the event the police decide to run a sweep.
