You may want to bone up on Canadian prositution laws .
I did before I posted. The new law, passed in 2014 and upheld recently, says that it is illegal to profit from prostitution, e.g., brothels, advertising, but not illegal for an individual selling sex in exchange for money.
Seems to me it you are correct about my post if indeed she is working for an agency
if they advertised for her services as a prostitute.
Since The Exiled said that "She is now back in Montreal Canada working for an agency using the name Alanna charging only $200 in Canadian dollars which is about $155 U.S."
my guess, based solely from the low price for such a high end prostitute, is that the agency is charging for her nonsexual services as an escort (people do hire them for certain nonsexual functions or functions at relatively tame bachelor or bachelorette parties where nudity but not sex is involved) and whatever additional and private negotiations for sexual services between her and the client are legal for her.
If any of this is incorrect kindly tell me of your sources. Mine are Wikipedia and other legit Canadian news outlets.
