The vast majority of appointments made in the GTA do not require references as opposed to the U.S. (where OP is coming from) where it is much more common.
As I said, "rarely required". Who wants to give up personal info if they don't need to?
An outcall at your hotel has been legal for you and her for many decades, (and even the illegal status of incalls has been challenged under the Charter, on which we're currently awaiting the Supreme Court's ruling) so we're not accustomed to the sort of police jeopardy that makes references a useful precaution in the States.
For an outcall, familiarize yourself with any security issues for receiving guests at your hotel, then call the SP or agency of your choice. More than likely they'll know the drill for the address, but since any two adults can legally make any sort of deal for paid sex as long as they do so in private, no one will be shy about discussing mere access. She's just another guest, and her profession is no concern.
We made and have hung onto laws against bawdyhouses, though
not against bawds, or johns. So incalls
are illegal (although with most enforcement in abeyance pending the ruling) Thus the trick-of-no-evidence is getting you and her into the room alone together, as everything done consensually afterwards is legal*. Your phone call to the agency or to the lady herself will likely give no more than a nearby major intersection as an address, and just what might be explicitly discussed varies widely. Once you have confirmed at the appointed time, that you are at the intersection you'll get the final address, entry buzz-codes, and suite number. It is important to remember that
the incall operation is NOT legal even if what you and she do is, so be discreet in the public areas, and if you must knock, do so very quietly. Save the "Hello! Aren't
you gorgeous!!" for inside. And as the first order of business will likely be payment, that's when you can discuss—quite safely—what it's for.
*The legal danger you run as a customer is discussing deals in public places like the street, (which is a crime and viewed seriously), or of being charged as a 'found-in' (also a crime) in the unlikely event the police thought they had the evidence to make bawdyhouse charges stick, and thought it wouldn't make them a laughingstock, given that the Supremes may well agree with the two lower courts who ruled the bawdyhouse provisions were contrary to the Charter and therefore invalid. The folks really in danger if bawdyhouse charges are laid are the operators; thus you will almost never find them on premises, and almost always operating form celphones.
If you think with the higher head for a moment, you'll see that the bawdyhouse danger also applies to any sort of sex being sold in licensed massage parlours and in stripclubs. Even if police evidence fell short of criminal conviction, these places depend on being licensed. But since there is no offence of being or buying a prostitute, as long as everyone determinedly doesn't notice, anything can happen in the dark ViP, or in that massage room. But management must never know.
Not that anything untoward ever does happen in such places, of course.
