[Rnair21]

Hello, I was wondering if anyone can see what appointments are available right now. I didn't pay the fee yet but I see that no tentative dates are available in Vancouver. I really need an appointment for nov 18th, preferably in Vancouver. If anyone is planning to cancel an appointment please let me know. I know they are gone pretty quickly , that's why I'm asking for a heads up. Please help !
