The first person that comes to mind would be April Killian (ex april rose) not only because she's quite good at that but also because she pretty much knows every indy in Montreal and could recommend someone for a duo. Other people come to mind too but yeah you can also browse the section mentioned above. TBH there are not a lot of discussions around the kinky stuff here.
Also, finding one of several dominas in Montreal shouldn't be much of a challenge.
PM me if you don't get any answers.
