Most
Calgary escorts work through a massage parlor or agency. There are very few independent ladies who are based there.
It is a huge city for touring ladies, and a number of
Vancouver escorts, as well as ladies from Toronto and Montreal seem to visit there frequently.
You may want to check the advertising here under the 'other Canada reviews' for touring ladies or check out the front page of the 'baby cow' board to see who is currently available there. I'll PM you the url for the other board in case you aren't familiar with it.
Best wishes, and have fun!
