Let me suggest that there be a scale for "gifts" for escorts etc according to where you have a Driver's Licence/ ID from. Reason being U.S tourists get all the provincial tax back on departing Canada on all "purchases". Let me suggest a scale for payment like for example:Ontario/Quebec residents: 100; Anywhere else in Canada :120;U.S residents:150. It's only fair since Canadians don't get anything back from U.S when they depart U.S for Canada.
